Here are differences between Plant and Animal cell:

  • Cell Wall (not found in animal cell)
    • This is rigid strong outer layer that protects cell from osmosis (bursting) and supports the cell by maintaining the shape.
    • In prokaryotes, it is often made out of peptidoglycan
    • In eukaryotes, (fungi, plants) it is often made out of cellulose
  • Flagellum (exception, found in protozoan)
    • This is long microtubule structure that allows cell to move
    • Also note that sperm tail is called flagellum, but this is not typical cell structure.

(Lodish et al, 2000)

  • Chloroplast
    • Similar to mitochondria, have two membranes: inner membrane and outer membrane.
    • Inside of chloroplast is filled with thylakoid sacs (disk-like), often held in matrix (stroma) in grana stacks.
    • The green pigments chlorophylls in thylakoid membranes, other pigments and enzymes are used for ATP synthesis during photosynthesis by absorbing light.
    • Contains own DNA
  • Vacuoles (only in plant)
    • Site of storage for ions and nutrients
  • Granules (only in plant)
    • Site of extra starch storage
  • Centrioles (only in animal cells)
    • Spindle fibers are synthesized during cell division to separate chromosomes
