Cells Structure and Function

Animal cell

  • Centrioles- A ring of a group of fused microtubules; put to work for the process of mitosis and miosis

Plant cell

  • Cell Wall- A protective cell wall made up of polysaccharides; provide and maintain the shape of the cell


  • Cell membrane- keep the peices inside; a protective barrier to the uncontrolled flow of water
  • Cytoplasm- internal soup, mostly water; bacterial metabolism
  • Nucleus- enclosed in a double membrane; controls eating, movement, and reproduction
  • Nucleolus- prominent structure in the nucleus; produces ribosomes
  • Chromatin- heredity
  • Ribosomes- packets of RNA; protein synthesis
  • Golgi Apparatus- membrane bond structure with a single membrane; packaging macromolecules
  • Endoplasmic reticulum- continuation of the outer nuclear membrane; breaks down toxins to control calcium release
  • Mitochondria- power centers; provide energy
  • Lysosomes- contains hydrolytic enzymes for digestion; kill and digest bacteria
  • Peroxisomes- protect the cell from own toxic peroxides; breaks down toxic materials in the cell
  • Vacuole- storing nutrients and waste; hold water smaller than plants
  • Cytoskeleton- back bone of cell; help maintain cell shape
