Detailed explanation-1: -A cell wall is a rigid and tough layer that provides structural support and protection to the plant. The cell wall is exclusively present in plant cells and is absent in animal cells.

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: -All cells have a cell wall. 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-4: -Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant’s life style.
