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
Both
- 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
