because animal cells use the cell membrane to hold the cell together. this in turn gives the animal cell more flexibility and gives it the ability to use specialized procedures. Also the plants cell wall protects the cell from damage (the p...

plant cells have cell walls for structure and protection. animal cells do not have this because their cells are a lot more flexible

The cell wall alows the cell to become turgid e.g. the pressure of water within a cell can build up, causeing the cell inself to increase in size and become rigid. This means that in theory it supports the whole plant. For example with out ...

This activity allows students to strip away the cell walls of plant cells (using enzymes) and then observe the resulting spherical protoplasts (plant cells minus the cell wall). Students see that plant cells indeed have a plasma membrane in addition to a cell wall.
