LIFE SCIENCE

Detailed explanation-1: -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-2: -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.

Detailed explanation-3: -The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

Detailed explanation-4: -Plant cells are like small balloons surrounded by a strong cell wall. Their internal pressure can be higher than the pressure in a car tire. It is this pressure that gives non-woody plant tissue its shape.
