Why doesn't an animal cell have a cell wall?

In: Microbiology, Cells and Genetics

[Edit]

Animal cells have a cell membrane instead of a cell wall.

Animal tissue is flaccid. This means that it is soft, pliable and not as heavy as plant tissue. This is part of what enables animals to move. Plants have no skeleton or exoskeleton, and are held up by their tissue. The plant tissue is made up of cells with rigid cell walls. Animal cells anchor onto a skeleton, and have a flaccid cell membrane.

The simple answer would be this: they don't need one. In the brutally competitive business of survival, expensive and unneeded things get dropped quickly.
