organelles

    Cards (12)

    • cytoplasm/cytosol: liquid portion of cell made up of salts, water and organic molecules. gives cell its shape and holds other organelles inside the cell.
    • cell membrane/plasma membrane: controls what goes in and out of the cell, made of phospholid bilayer > made of two layers of fat called lipids
    • nucleus: stores DNA and controls cell activity. is membrane bound
    • mitochondria: produces energy, has DNA, and is surrounded by a double membrane
    • smooth endoplasmic reticulum (smooth ER): membrane bound organelle with tube-like structure that produces lipids and detoxifies cell. network of cisternae
      rough endoplasmic reticulum (rough ER): membrane bound, covered in ribosomes and produces proteins to be exported out of cell. stack of cisternae
    • ribosomes: not membrane bound, sticks to rough ER, made of proteins and rRNA. makes proteins
    • golgi apparatus: membrane bound, processes and packages proteins from rough ER to plasma membrane so it can be released out of cell. stack of cisternae.
      vesicles: transport materials
    • lysosomes: membrane bound, made of proteins and rRNA. destroys proteins and toxins, uses acidic enzymes to break down waste
    • centrioles: not membrane bound, made up of microtubules and assists in cell division and formation of cell structures
    • cell wall: only in plant cells, outermost layer of plant cell providing strength, support, protection and shape for the cell. made of cellulose and other proteins
    • vacuoles-
      in plants: large membrane bound organelle to maintain cell shape, provide nutrients and maintain water balance
      in animals: have smaller and more, used to handle waste products
    • chloroplasts: thylakoid discs inside it contain chlorophyll, which absorbs light energy for photosynthesis and gives plants its green colour.
