Detailed explanation-1: -The main function of the cell wall is to provide structural strength and support, and also provide a semi-permeable surface for molecules to pass in and out of the cell.
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: -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-4: -The cell is surrounded by a plasma membrane (or cell membrane) to separate the cell contents from the external environment. Biology definition: A cell wall is a structural layer next to the cell membrane with the primary role of giving the cell rigidity and protection from mechanical stress.
Detailed explanation-5: -As plants cannot move from one place to another so they need greater protection against variations in temperature, high wind speed, atmospheric moisture, etc. Therefore, for protection they have an additional layer surrounding the cell membrane This layer is called the cell wall.
