NEET BIOLOGY

Detailed explanation-1: -A plant cell has a square or rectangular shape while the animal cells have an irregular or round shape.

Detailed explanation-2: -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-3: -The cell wall which is made up of cellulose gives the plant cell rigidity resulting in a fixed, rectangular shape. Animal cells lack the rigidity hence, they tend to have a round and irregular shape.

Detailed explanation-4: -Plant cells are not necessarily square, but they due tend to have distinct edges and be somewhat rectangular. This structure is caused by the cell wall which is very rigid and therefore forces the cell to have a defined shape.

Detailed explanation-5: -An animal cell is usually irregular and round in shape. This is primarily due to the absence of the cell wall, which is a characteristic feature of plant cells. Furthermore, animal cells do not have plastids as animals are not autotrophs.
