Plant Cell Walls

Plant cell walls are sturdy structures that surround the cell membrane, providing support and protection. Made primarily of cellulose, a complex carbohydrate, they give plants their shape and prevent them from bursting when water pressure inside increases. Cell walls also help regulate what enters and exits the cell and contribute to the plant’s overall strength, allowing it to stand upright and resist external forces. In addition, they play a role in communication between cells and in the plant’s growth and development. Overall, cell walls are essential for maintaining the structural integrity and function of plant cells.
