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 cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells.
Detailed explanation-4: -So, the correct answer is ‘Sclerenchyma’.
Detailed explanation-5: -The epidermis is the protective outer layer of clonally related cells covering all plant organs. It is composed of a number of specialised cell types which differentiate from the basal epidermal cell in adaptively significant frequencies and patterns.
