Detailed explanation-1: -The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The central vacuole maintains turgor pressure against the cell wall.

Detailed explanation-2: -Cell wall is present outside the cell membrane. It has the function of giving shape and rigidity to the cell. Cell wall is present only in plants hence it is the characteristic feature that distinguishes between plant and animal cells.

Detailed explanation-3: -Cells of bacteria, fungi, algae, and higher plants are surrounded by rigid cell walls, which are an integral part of the cell. Although not encased in cell walls, animal cells in tissues are closely associated with an extracellular matrix composed of proteins and polysaccharides.
