Why don't animal cells have cell walls?
Animals have only cell membranes made up of phospholipid bilayer and protein which protects and hold together the cell and its parts,
1. their shape, animal cells are round and morphus, whereas, plant cells are like rectangular, like bricks. 2. the organelles, animal cells don't have 'chloroplasts' which make the plant green. 3. their cell walls- an animal cell has a soft cell wall, where a plant cell has a hard outer coating and then a soft internal coating.
