Question

why do plant need a rigid cell wall​

Answer 1

Answer:

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.

Answer 2

Answer:

Forming the interface between adjacent cells, plant cell walls often play important roles in intercellular communication. Because of their surface location, plant cell walls play an important role in plant-microbe interactions, including defense responses against potential pathogens.

Cell Walls are necessary in plants because they help the cells maintain their shape and maintain the structural integrity of the object.
