Detailed explanation-1: -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-2: -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-3: -The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Detailed explanation-4: -Plasma membrane is the outermost protective layer in cells of all plants and animals.
Detailed explanation-5: -The cell wall is the outermost layer of a plant cell. It makes the cell stiff and gives it protection. Animal cells do not have cell walls. The cell membrane is a protective layer that surrounds every cell.
