There are two types of cells, cells of prokaryotic and eukaryotic cells. Prokaryotic cells is independent in nature, such as bacteria and archaea. On the other hand, the cells of all multi-cellular creature is a eukaryotic cell. Both animal cells and plant cells are eukaryotic cells, but they have a different structure.
The main difference between animal cells and plant cells is that plant cells have a cell wall, where animal cells do not have it. The cell walls are composed of cellulose provides rigidity plant cell to produce a fixed shape that is rectangular shape.
