CELL PARTS YEARBOOK PERIOD 5 2011-2012 Golgi Body (Golgi Apparatus) O O O O Golgi Bodies function and form there structures in most of the eukaryotic cells. The Golgi Body likes to hang out near the top of a cell. The Golgi Body secretes the wastes out of a cell. Since it is so big there are only one Golgi Body per cell. Name: Kristal Amos-Whitfield Class Period: 5 Nuclear Pore These Pores are found in almost all types of cells, specifically the eukaryotic cell. Nuclear pore complexes allow the transport of water-soluble molecules across the nuclear envelope. There are about 2000 Nuclear Pores surrounding the Nuclear Envelope! Can typically be seen carrying RNA Favorite Hang Out Spot The Nuclear Pores can be found on the nuclear envelope, which is the double membrane surrounding the eukaryotic cell nucleus. Austin Briffa, P5 Favorite hang out spot: towards the outside of the cell. It seperates the interior of a cell from the outside of a cell. Hobbies: anchoring the cytoskeloten to provide shape to the cell, substances use it to move across through diffusion, and serve as the attachment surface for several extracellular structures. Extracurricular activities: There is a cell membrane is every type of cell including plant cells, animal cells, prokaryotic cells and etc. Siblings: There is only one cell membrane found in a cell. RaeLynn Chapman Period. 5 Nuclear Membrane Favorite Hang-Out Spot: Near the inside of the cell. Hobbies: It is a wall that blocks the nucleus and cytoplasm from meeting. Also, it is in charge of the substances that come in and out of the nucleus. Extracurricular Activities: Found in all animal and plant cells. Siblings: It does not have any siblings. Jessica Rubin P.5 Lysosome • Favorite Hang-Out Spot: Near the outside (In the Cytoplasm) • Hobbies: Hold enzymes, digest food, break down cell once it dies, fuses with other organelles, engulf viruses or bacteria • Extracurricular Activities: Eukaryotic Cells, found in only animal cells • Siblings: Varies; no definite amount Sam Mok Pd.5 (Cilia – Plotkin) Favorite hangout spot: Outside of the cell Hobbies: In primary Cilia which typically serve as sensory organelles such as the eyes and nose, in motile Cilia, they sweep mucus and dirt out of the lungs Extracurricular Activities: In some plant cells, Cilia is found, and in almost all animal cells, Cilia is found with a few exceptions Siblings: hundreds or thousands Molly Plotkin Period 5 It is usually seen in the middle of the cell yet doesn’t have a specific spot it is in. Favorite Hang-Out Spot: Extracurricular Activities: The vacuole is found in all plant and animal cells. In an Animal cell there is one or more smaller vacuoles. Yet in a Plant cell, there is one large vacuole, usually taking up about 90% of the cell. Siblings: The vacuole exports materials that can be harmful or that are unwanted in the cell. It contains water for plant cells. Also it contains waste products as well as removes them. Basically, maintaining the fluids, storing food, and it enables the cell to have/change structure. Hobbies: Natalia Morales Period 5 Nucleoplasm Favorite Hang-out spot: Nucleoplasm is found around the middle of the cell, around the nucleus. Hobbies: It just acts as a fluid/medium which many substances are dissolved in it, such as nucleotides, for replication of DNA & enzymes, direct activities that take place in the nucleus. It also contains & carries some important structure inside it. Extracurricular Activities: Nucleoplasm is found in all eukaryotic cells which are cells that have a nucleus. Siblings: There is only one type of nucleoplasm but there are many different types of plasm in a eukaryotic cell. Sheena Kothary 5 CHROMOSOME Favorite Hang-Out Spot: Chromosomes are visible in the cell’s nucleus— with a powerful microscope Hobbies: Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes. Extracurricular Activities: Found in all kind of cells including plant cells, and animal cells Siblings: There are 46 in each human body cell, but the number varies depending on the organism. Noor Rana Period 5 Biology Ribosome Colin Stern Period 5 Favorite Hang-out Spot: Depending on the type of cell, it can be found anywhere in the cytoplasm Siblings: The number of mitochondria in a cell varies widely by organism and tissue type Extracurricular Activities: Found in most eukaryotic cells Kian Jackson Period 5 Hobbies: •generate most of the cell's supply of adenosine triphosphate (ATP), for use as chemical energy •Involved in signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth •May play a role in the aging process Favorite Hang-out spot: the nucleus can be found in the middle of every cell. Hobbies: • stores the cell’s hereditary material/DNA, the information stores in the DNA directs the activities of the cell. • Also the nucleus coordinates the cell’s activities, which includes growth, intermediary, metabolism, protein synthesis, and reproduction. Extracurricular activities: the nucleus in found in every single cell, plant or animal. Siblings: Generally there is only ONE nucleus per cell. Shweta Chopra P5. Microfilaments • This structure can be found anywhere in the cytoplasm of a cell, but is usually found near the edges • The main function is to keep the structure of a cell • The structure also provides mechanical support • This can be found only in Eukaryotic cells, whether animal or plant Microfilaments-Tvizer Vesicle Vesicle Favorite Hang-Out Spot: Near the edge of the cell Hobbies: Transporting and storing molecules throughout the cell Extracurricular Activities: Found in Eukaryotic cells (animal and plants) Siblings: Several vesicles can be found in one cell Kylie Mulhall, Period 5 Hobbies: Chloroplast captures light to conserve energy through a process called photosynthesis. Siblings: There are typically 10 to 100 chloroplasts per cell. Favorite hangouts: You can find Chloroplast scattered through the cytoplasm. Extracurricular Activities: Chloroplast makes plants green and removes carbon dioxide from the air. Carly Meyers pd. 5 • • • • • Found near the outside of the cell. Helps the cell sense chemicals and temperatures outside the cell. Helps the cell move around. Found in bacterial cells. Some cells may only have one flagellum, and some have several flagella, the amount of flagella depends on the cell. Mike Bush Period 5 Favorite hangout spot: The Nucleolus is found inside the nucleus. The Nucleolus is found in all cells with a nucleus. Nucleolus In the cell the Nucleolus holds the DNA/RNA inside the nucleus. There is only one Nucleolus in each cell. Centrosome Diagrams • Jennie Rothschild About the Centrosome Favorite Hang-Out Spot: Directly surrounds the cytoplasm surrounding the centrioles. Hobbies: Serves as the main microtubule organizing center. Extracurricular Activities: Exists in Both Animal And Plants. Siblings: One centrosome to a cell Jennie Rothschild ROUGH ENDOPLASMIC RETICULUM BY: JEREMY WAI 5 TH P E R I O D FAVORITE HANG-OUT SPOT The Rough Endoplasmic Reticulum is located around the nucleus, which is around the center of the cell, and they are attached to one another. HOOBIES Rough ER is a membrane that creates a network of channels throughout the cytoplasm. Attachment of ribosomes to the membrane gives a rough appearance Synthesis of proteins to be secreted, sent to lysosomes or plasma membrane EXTRACURRICULAR ACTIVITIES The Rough Endoplasmic Reticulum is found in both the animal cell and the plant cell. Animal Cell Plant Cell SIBLINGS There are couple Rough Endoplasmic Reticulum in each cell (varies), and there are many ribosomes on it (That’s what gives Rough Endoplasmic Reticulum its name. The ribosomes make the surface rough.) . There are also parts called ER Lumen, Cisternae, transport vesicle, and transitional ER. The Cell Wall’s likes to hangout around the very outside of the plant cell. The Cell Wall keeps the Plants Shape and protect the cell. The Cell Wall is only found in plant cells. The Cell Wall doesn’t have any duplicates. Its one of a kind in its own cell. There is only one Cell Wall in the cell. Nasir Haines 5th period Microtubules • • • • • • Microtubules are hollow tubes made of globular proteins. they are found in cilia, flagella, and centrioles, which are mostly located near the edges of the cell They have a role in determining cell structure as part of the cytoskeleton. There are many microtubules in the cell, which help to form the aforementioned structures These are found in all plant and animal cells, as they need cytoskeletons to preserve their form, like vertebrates need a skeleton. Microtubules also form spindle fibers, which aid in the process of cell division. Centriole Hobbies: They like to help the cell divide during mitosis and meiosis, otherwise they cannot be seen clearly. During cell division you can see two pairs of them. One pair moves to the opposite side of the nucleus and they both send out meiotic spindles. The meiotic spindles release threads that connect to the chromosomes. The threads released help split and pull the chromosomes towards each pair of centrioles and when the whole cell splits apart the chromosomes begin to unravel and a new nuclear pocket begins to appear. Favorite Hang-Out Spot: They are located in the centrosome, which is in the cytoplasm near the nucleus. Siblings: Usually two pairs during cell division. Generally one pair during Interphase. Extracurricular Activities: All Animal cells Hima Koneru Period: 5 It is found on the outside of the nucleus membrane Smooth Endoplasmic Reticulum is an organelle of eukaryotic cells it forms an interconnected network of tubule, vesicles and cisternae its main function is synthesize lipids and steroids, and regulates calcium is found in both plants and animal cells Jamel Johnson
