What is the cell wall of a plant cell? in an animal cell? fungal cells?

The cell walls of representatives of different kingdoms differ in their structure. For example, the cell wall of animal cells is not as strong as the cell wall of plants and fungi. Plants have the strongest shell. It is because of this that plant foods are much worse digested. Digestive enzymes are often unable to completely digest some plant foods. Animal food is digested very quickly and easily, since the cell walls are not very strong and are quickly destroyed with the help of special enzymes.
