Detailed explanation-1: -Plant cells have a cell wall and plastids that animal cells lack.
Detailed explanation-2: -In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
Detailed explanation-3: -Animal cells do not have cell wallsbecause they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if eachcell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones .
Detailed explanation-4: -Plant cells have a cell wall in addition to a cell membrane, whereas animal cells have only a cell membrane. Plants use cell walls to provide structure to the plant. Plant cells contain organelles called chloroplasts, while animal cells do not.
Detailed explanation-5: -So, plants have cell walls as they don’t move. But animals cannot have walls at all, because, that would prevent them from moving freely.
