These are ways we incorporated this model into our lesson plan: active engagement through anticipatory set activity, visuals through PowerPoint, student involvement in lesson by asking questions, hands-on learning through group activity to draw component of the cell, practice on own at home for additional learning, supplemental material given to ELLs in case they have questions (all fact sheets are available for students that need additional information). *Engagement 90% to100% of time, chew and chunk for every 10 minutes of input 2 min of processing time, Corners Method? Of instruction (corners with descriptions of part of the cell) POWERPOINT: SLIDE: Intro to cells SLIDE: Find a partner SLIDE: Cell Membrane: City limits WHAT IS A CELL? The cell is the basic structural, functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing, and are often called the "building blocks of life". Cells consist of a protoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.[1]Organisms can be classified as unicellular (consisting of a single cell; including most bacteria) or multicellular (including plants andanimals). While the number of cells in plants and animals varies from species to species, humans contain about 100 trillion (1014) cells.[2]Most plant and animal cells are visible only under the microscope, with dimensions between 1 and 100 micrometres.[3] The cell was discovered by Robert Hooke in 1665. The cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that all cells come from preexisting cells, that vitalfunctions[disambiguation needed] of an organism occur within cells, and that all cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.[4] Cells emerged on Earth at least 3.5 billion years ago.[5][6][7] The word cell comes from the Latin cella, meaning "small room".[8] It was coined by Robert Hooke in his book Micrographia (1665), in which he compared the cork cells he saw through his microscope to the small rooms monks lived in.[9] The 'cell membrane' (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from theoutside environment.[1][2] The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.[3] The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins. Cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivityand cell signaling and serve as the attachment surface for several extracellular structures, including the cell wall,glycocalyx, and intracellular cytoskeleton. Cell membranes can be artificially reassembled.[4][5][6] SLIDE: Nucleus: Control Center, DNA, information, news paper (Town Hall) In cell biology, the nucleus (pl. nuclei; from Latin nucleus ornuculeus, meaning kernel) is a membraneenclosed organelle found ineukaryotic cells. It contains most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes. Thegenes within these chromosomes are the cell's nuclear genome. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression — the nucleus is, therefore, the control center of the cell. The main structures making up the nucleus are the nuclear membrane, a double membrane that encloses the entire organelle and isolates its contents from the cellular cytoplasm, and the nucleoskeleton (which includes nuclear lamina), a network within the nucleus that adds mechanical support, much like the cytoskeleton, which supports the cell as a whole. Movement of large molecules such as proteins andRNA through the pores is required for both gene expression and the maintenance of chromosomes. Because the nuclear membrane is impermeable to large molecules, nuclear pores are required that regulate nuclear transport of molecules across the envelope. The pores cross both nuclear membranes, providing a channel through which larger molecules must be actively transported by carrier proteins while allowing free movement of small molecules and ions. The interior of the nucleus does not contain any membrane-bound sub compartments, its contents are not uniform, and a number of sub-nuclear bodies exist, made up of unique proteins, RNA molecules, and particular parts of the chromosomes. The best-known of these is the nucleolus, which is mainly involved in the assembly of ribosomes. After being produced in the nucleolus, ribosomes are exported to the cytoplasm where they translate mRNA. SLIDE: Organelles: In cell biology, an organelle /ɔrɡəˈnɛl/ is a specialized subunit within a cell that has a specific function, and it is usually separately enclosed within its own lipid bilayer. The name organelle comes from the idea that these structures are to cells what an organis to the body (hence the name organelle, the suffix -elle being a diminutive). Organelles are identified by microscopy, and can also be purified by cell fractionation. There are many types of organelles, particularly in eukaryotic cells. While prokaryotes do not possess organelles per se, some do contain protein-based microcompartments, which are thought to act as primitive organelles.[1] SLIDE: Mitochondria: powerhouse, makes energy (ATP), Power Plant The mitochondrion (plural mitochondria) is a membrane-enclosed structure found in most eukaryotic cells (the cells that make up plants, animals, fungi, and many other forms of life).[1] Mitochondria range from 0.5 to 1.0 micrometer (μm) in diameter. These organellesare sometimes described as "cellular power plants" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.[2] In addition to supplying cellular energy, mitochondria are involved in other tasks such assignaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth.[3] Mitochondria have been implicated in several human diseases, including mitochondrial disorders[4] andcardiac dysfunction,[5] and may play a role in the aging process. The word mitochondrion comes from the Greek μίτος, mitos, i.e. "thread", and χονδρίον, chondrion, i.e. "granule".[6] Several characteristics make mitochondria unique. The number of mitochondria in a cell varies widely by organism and tissue type. Many cells have only a single mitochondrion, whereas others can contain several thousand mitochondria.[7][8] The organelle is composed of compartments that carry out specialized functions. These compartments or regions include the outer membrane, the intermembrane space, the inner membrane, and the cristae and matrix. Mitochondrial proteins vary depending on the tissue and the species. In humans, 615 distinct types of proteins have been identified from cardiac mitochondria,[9] whereas in rats, 940 proteins have been reported.[10] The mitochondrial proteome is thought to be dynamically regulated.[11] Although most of a cell's DNA is contained in the cell nucleus, the mitochondrion has its own independent genome. Further, its DNA shows substantial similarity to bacterial genomes.[12] SLIDE: Endoplasmic Reticulum: rough and smooth (rough: makes energy and translation), (smooth: metabolic activities), contains Ribosomes, *Highway and City Street comparisions The endoplasmic reticulum (ER) is a type of organelle in the cells ofeukaryotic organisms that forms an interconnected network of flattened, membrane-enclosed sacs or tubes known as cisternae. The membranes of the ER are continuous with the outer membrane of the nuclear envelope. Endoplasmic reticulum occurs in most types of eukaryotic cell but is absent from red blood cells and spermatozoa. There are two types of endoplasmic reticulum, rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The outer (cytosolic) face of the rough endoplasmic reticulum is studded with ribosomes that are the sites of protein synthesis. Rough endoplasmic reticulum is especially prominent in cells such as hepatocyteswhere active protein synthesis is occurring. The smooth endoplasmic reticulum lacks ribosomes and is concerned with lipid metabolism,carbohydrate metabolism, and detoxification[citation needed] and is especially abundant in mammalian liver and gonad cells. The lacey membranes of the endoplasmic reticulum were first seen in 1945 by Keith R. Porter, Albert Claude, and Ernest F. Fullam.[1] SLIDE: Golgi Body: packaging and transport *Mail carrier/post office The Golgi apparatus (/ˈɡoʊldʒiː/), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells.[1] It was identified in 1897 by the Italian physician Camillo Golgi and named after him in 1898.[2] Part of the cellular endomembrane system, the Golgi apparatus packages proteins inside the cell before they are sent to their destination; it is particularly important in the processing of proteins forsecretion. SLIDE 9: Vacuole File:A dry fracture of a Vero cell exposing the contents of a vacuole where Coxiella burnetii (the Bacteria that cause Q Fever) are busy growing - NIAID.jpg *Store Energy/ self distruct cell, A vacuole is a membrane-bound organelle which is present in all plant andfungal cells and some protist, animal[1] and bacterial cells.[2] Vacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution, though in certain cases they may contain solids which have been engulfed. Vacuoles are formed by the fusion of multiple membrane vesicles and are effectively just larger forms of these.[3] The organelle has no basic shape or size; its structure varies according to the needs of the cell. The function and significance of vacuoles varies greatly according to the type of cell in which they are present, having much greater prominence in the cells of plants, fungi and certain protists than those of animals and bacteria. In general, the functions of the vacuole include: Isolating materials that might be harmful or a threat to the cell Containing waste products Containing water in plant cells Maintaining internal hydrostatic pressure or turgor within the cell Maintaining an acidic internal pH Containing small molecules Exporting unwanted substances from the cell Allows plants to support structures such as leaves and flowers due to the pressure of the central vacuole In seeds, stored proteins needed for germination are kept in 'protein bodies', which are modified vacuoles. [4] Vacuoles also play a major role in autophagy, maintaining a balance betweenbiogenesis (production) and degradation (or turnover), of many substances and cell structures in certain organisms. They also aid in the lysis and recycling of misfolded proteins that have begun to build up within the cell. Thomas Boller [5] and others proposed that the vacuole participates in the destruction of invading bacteria and Robert B Mellor proposed organ-specific forms have a role in 'housing' symbiotic bacteria. In protists, vacuoles have the additional function of storing food which has been absorbed by the organism and assisting in the digestive and waste management process for the cell. [6] The vacuole probably evolved several times independently, even within the Viridiplantae.[7] SLIDE: Lysosome: Digestion of substance *Decomposers/ garbage members *Hospitals? Lysosomes (derived from the Greek words lysis, meaning "to separate", andsoma, "body") are the cell's waste disposal system and can digest some compounds. They are used for the digestion of macromolecules fromphagocytosis (ingestion of other dying cells or larger extracellular material, like foreign invading microbes), endocytosis (where receptor proteins are recycled from the cell surface), and autophagy (wherein old or unneeded organelles or proteins, or microbes that have invaded the cytoplasm are delivered to the lysosome). Other functions include digesting bacteria (or other forms of waste) that invade a cell and helping repair damage to the plasma membrane by serving as a membrane patch, sealing the wound. In the past, lysosomes were thought to kill cells that are no longer wanted, such as those in the tails of tadpoles or in the web from the fingers of a 3- to 6-monthold fetus.

House demonstration Cell Raps: on YouTube An Egg is a cell Prokaryotes, Eukaryotes, & Viruses Tutorial Eukaryotes Basic structure The basic eukaryotic cell contains the following: 1. 2. 3. 4. plasma membrane glycocalyx (components external to the plasma membrane) cytoplasm (semifluid) cytoskeleton - microfilaments and microtubules that suspend organelles, give shape, and allow motion 5. presence of characteristic membrane enclosed subcellular organelles Characteristic biomembranes and organelles Plasma Membrane A lipid/protein/carbohydrate complex, providing a barrier and containing transport and signaling systems. Nucleus Double membrane surrounding the chromosomes and the nucleolus. Pores allow specific communication with the cytoplasm. The nucleolus is a site for synthesis of RNA making up the ribosome. Mitochondria Surrounded by a double membrane with a series of folds called cristae. Functions in energy production through metabolism. Contains its own DNA, and is believed to have originated as a captured bacterium. Chloroplasts (plastids) Surrounded by a double membrane, containing stacked thylakoid membranes. Responsible for photosynthesis, the trapping of light energy for the synthesis of sugars. Contains DNA, and like mitochondria is believed to have originated as a captured bacterium. Rough endoplasmic reticulum (RER) A network of interconnected membranes forming channels within the cell. Covered with ribosomes (causing the "rough" appearance) which are in the process of synthesizing proteins for secretion or localization in membranes. Ribosomes Protein and RNA complex responsible for protein synthesis. Smooth endoplasmic reticulum (SER) A network of interconnected membranes forming channels within the cell. A site for synthesis and metabolism of lipids. Also contains enzymes for detoxifying chemicals including drugs and pesticides. Golgi apparatus A series of stacked membranes. Vesicles (small membrane surrounded bags) carry materials from the RER to the Golgi apparatus. Vesicles move between the stacks while the proteins are "processed" to a mature form. Vesicles then carry newly formed membrane and secreted proteins to their final destinations including secretion or membrane localization. Lysosymes A membrane bound organelle that is responsible for degrading proteins and membranes in the cell, and also helps degrade materials ingested by the cell. Vacuoles Membrane surrounded "bags" that contain water and storage materials in plants. Peroxisomes or Microbodies Produce and degrade hydrogen peroxide, a toxic compound that can be produced during metabolism. Cell wall Plants have a rigid cell wall in addition to their cell membranes.

Faith turns into religion as is discussed in James chapter 2 when the structure or the works of faith are over emphasized and not the relationship between God and man. Since religion is the frame work of the belief system it is of importance, but is not the sole ingredient. The importance of faith comes into play the discussion of doctrine which is the foundation or cornerstone which the faith is built. An improper foundation leads to a destructive faith and faulty religion. Is Religion just a form of faith or is it a formal practice of a faith? Religion can be a form of faith and a formal method to practice faith but is not always the case. A person can go through the motions of religion and not result in an inward change of heart. A person who applies faith in their practice goes through a metamorphosis of their inward heart. Religion can cause false perceptions of people who look righteous on the outside, but are living a hypocritical life within. As Jesus described the hypocritical religious Pharisees as white washed tombs, so religion can be used as just an outward expression of a non-relevant inward change. Is religion related to a denomination, church, or even an “ism”? A religion has its basis in a central doctrine agreed by a group of individuals. Denominations are developed by people who either interpret the doctrine differently or would like to conduct the church service in a specific way that would be different to the likings of all the members. Religion is the umbrella term for denomination, church and “isms” and must be further identified to identify the context where it is being discussed.
