Detailed explanation-1: -Plant cells have a cell wall, as well as a cell membrane. 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-2: -Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.

Detailed explanation-3: -Unlike the animal extracellular matrix, which is rich in protein and other nitrogen-containing polymers, the plant cell wall is made almost entirely of polymers that contain no nitrogen, including cellulose and lignin.

Detailed explanation-4: -Moreover plant cells have cell wall because plants do not move from one place to another and hence they require rigidity which is provided by the cell wall but animal cells move. The cell wall if present in the animal cell will be a hindrance to movement.

Detailed explanation-5: -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 .
