NEET BIOLOGY

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 are rectangular shaped, eukaryotic, or nucleus-containing, cells with a rigid cell wall. Within the plant cell structures called organelles, perform functions necessary to cell and plant survival.

Detailed explanation-3: -For example, animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes.

Detailed explanation-4: -The main difference between an animal cell and a plant cell is that plant cells have a cell wall and animal cell lacks the cell wall. The cell wall which is made up of cellulose gives the plant cell rigidity resulting in a fixed, rectangular shape.

Detailed explanation-5: -They are often square shaped/rectangular because it is easier to build a “brick wall” (cell wall) out of rectangular bricks.
