What is the role of the cell wall in plants?

The cell wall in plants is primarily responsible for providing structure and protection. It is composed mainly of cellulose, which gives rigidity and strength to the plant cells, enabling them to maintain their shape and withstand various environmental stresses, such as wind and water loss. The cell wall also plays a crucial role in protecting the plant from pathogens and physical damage.

In addition, the rigidity of the cell wall helps plants stand upright, allowing them to access sunlight for photosynthesis. Unlike animal cells, which do not have a cell wall, plant cells rely heavily on this structure to support their growth and development. The cell wall is essential for overall plant health and functionality, as it creates a barrier that supports the internal processes of the cell while providing strength and stability to the entire organism.
