plantcellwall
The plant cell wall is a rigid outer layer that surrounds the plasma membrane of plant cells. It provides structural support and protection to the cell, and it prevents excessive water uptake. The primary component of the plant cell wall is cellulose, a complex carbohydrate. Other components include hemicellulose, pectin, and lignin, the relative proportions of which vary depending on the plant species and cell type.
The cell wall plays a crucial role in maintaining cell shape and turgor pressure, which is the
In addition to structural functions, the plant cell wall acts as a barrier against pathogens and mechanical
