GENERAL HISTOLOGY

Detailed explanation-1: -Many plants use both turgor and lignin to stand upright.

Detailed explanation-2: -Plant cells have a cell wall, as well as a cell membrane. The cell wall provides structural support and protection. This gives the plant cells their distinct rectangular or pentagonal shape.

Detailed explanation-3: -The central vacuole contains cell sap that is surrounded by a single layer membrane called the tonoplast. The central vacuole’s main function is to maintain turgor pressure within the plant cell. This helps the plant cell to maintain its shape.

Detailed explanation-4: -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.
