B. List and describe the function of organelles inside of a cell CELL ORGANELLES The Nuts and Bolts of a Cell B. List and describe the function of organelles inside of a cell TERMS TO KNOW Organelle Plasma membrane Cell wall Mitochondria Golgi apparatus Lysosome Vacuole Centrioles Chromatin Endoplasmic reticulum Ribosome Cytoplasm Nucleus Nuclelous Nuclear membrane B. List and describe the function of organelles inside of a cell Animal Cell PLANT CELL B. List and describe the function of organelles inside of a cell CELL ORGANELLES Like many organisms cells have organs within them that have specific functions. They are called organelles Organelles are membrane-bound structures within a eukaryotic cell that have specific functions B. List and describe the function of organelles inside of a cell THE CELL MEMBRANE A selectively permeable layer on the outside of the cell All organelles are within Remember that the plasma membrane helps maintain homeostasis within an organism All cells have a cell membrane B. List and describe the function of organelles inside of a cell CELL WALL Rigid structure located outside the plasma membrane of PLANTS, Provides support and protection The cell wall allows the cell to become quite turgid without bursting Animal cells DO NOT have cell walls B. List and describe the function of organelles inside of a cell MITOCHONDRIA Membrane-bound organelle that transforms energy stored in food Mitochondria have highly folded membranes that produce energy-storing molecules Powerhouse of the cell B. List and describe the function of organelles inside of a cell GOLGI APPARATUS Flattened tubular membranes Sorts and packages proteins and sends them to their appropriate destinations B. List and describe the function of organelles inside of a cell LYSOSOME Contains digestive enzymes Responsible for digesting excess or worn out organelles, food particles, and engulfed viruses or bacteria B. List and describe the function of organelles inside of a cell VACUOLE A vacuole is a membrane-bound space in the cytoplasm of cells used for the temporary storage of materials The vacuole in a plant is very large B. List and describe the function of organelles inside of a cell CHLOROPLAST Conduct photosynthesis Capture light ONLY IN PLANTS B. List and describe the function of organelles inside of a cell CENTRIOLES Small cylindrical structures composed of microtubules called centrioles Duplicate during mitosis (when cells divide) ANIMAL CELLS ONLY B. List and describe the function of organelles inside of a cell ENDOPLASMIC RETICULUM Has highly folded membranes Surrounded by cytoplasm It is the site of cellular chemical reactions Rough “ER” has ribosomes attached Smooth ER does not have ribosomes B. List and describe the function of organelles inside of a cell RIBOSOMES Found in the nucleus OR suspended in the cytoplasm Where proteins are assembled B. List and describe the function of organelles inside of a cell CYTOPLASM Clear, gelatinous fluid in cells Site of numerous chemical reactions It suspends the organelles B. List and describe the function of organelles inside of a cell NUCLEUS Central organelle that manages cellular functions Contains DNA Surrounded by a nuclear membrane which can dissolve or allow structures out to the cytoplasm B. List and describe the function of organelles inside of a cell NUCLEOLUS The nucleolus is found IN the nucleus Produces ribosomes B. List and describe the function of organelles inside of a cell REVIEW To link to an Internet site on parts of the cell click here! B. List and describe the function of organelles inside of a cell SHRINKY DINKS! Steps: LIGHTLY sand each side of the plastic Choose either the plant or animal cell and trace it onto the plastic using permanent markers (black) Color the cell and organelles using colored pencils Number each organelle on the colored side, then list the numbers on the back along with the name of the organelle Take home, bake, and return for credit B.
