What is the function of a cell wall

Answer 1

The cell wall is a rigid, protective layer that surrounds the cell membrane of plant cells, fungi, algae, and bacteria. Its main functions include providing structural support and protection to the cell, maintaining the shape of the cell, preventing the cell from bursting due to osmotic pressure, and allowing the cell to adhere to other cells. Additionally, the cell wall regulates the passage of substances in and out of the cell, provides defense against pathogens, and helps to anchor the cell to its surroundings.
