NEET BIOLOGY

Detailed explanation-1: -Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The central vacuole maintains turgor pressure against the cell wall.

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: -A plant cell devoid of cell wall is called a protoplast. Protoplasts are employed in tissue culture protocols as explants.

Detailed explanation-4: -Explanation: Cell Wall: this provides extra strength and support for the plant cell so it doesn’t burst when gaining water by endosmosis. Chloroplasts: this is where photosynthesis takes place. Large permenant vacuole: this stores several pigments, ions, enzymes and organic and inorganic substances.

Detailed explanation-5: -The Plant Cell Wall: A Complex and Dynamic Structure As Revealed by the Responses of Genes under Stress Conditions. The plant cell wall has a diversity of functions. It provides a structural framework to support plant growth and acts as the first line of defense when the plant encounters pathogens.
