primary cell wall

The primary cell wall is a flexible, outer layer that surrounds plant cells. It is mainly made of cellulose, a strong carbohydrate, along with other materials like proteins and pectin. This wall provides structural support, helping the cell maintain its shape, while still allowing growth and expansion. It also acts as a barrier, protecting the cell from damage and controlling what enters and exits. The primary cell wall is essential for plant stability, growth, and interaction with their environment.
