Detailed explanation-1: -Plant cells are surrounded by a cell membrane and outside this is a fairly rigid cell wall. The cell wall gives the plant cell a more definite shape than an animal cell. Animal cells do not have a cell wall.
Detailed explanation-2: -Plant cells and animal cells differ from each other concerning some organelles. Cell walls are the rigid outer covering layer of the plant cell. It is made up of cellulose and polysaccharides that makes it tough and gives rigidity to plant cells. This is the reason that plant cells remain more rigid than animal cells.
Detailed explanation-3: -Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes. Plant and animal cells are both eukaryotic cells, so they have several features in common, such as the presence of a cell membrane, and cell organelles, like the nucleus, mitochondria and endoplasmic reticulum.
Detailed explanation-4: -The rigid exterior around the cells is necessary to allow the plants to grow upright. Animal cells do not have these rigid exteriors. There are other distinct differences between plant and animal cells.
Detailed explanation-5: -Plant cells have a rigid cell wall, a large central vacuole, and plastids. The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.
