C ELL W ALL By Sharon Girgenti & Jen Barrett

C ELL W ALL Composed of cellulose fiber, polysaccharides, and protein. Function: provides protection and support

C ELL WALL Primary Cell Wall The first cell wall of growing cells is called the primary cell wall. Functions: Protect against pathogens, dehydration, and other environmental factors Carbohydrate storage Structural and mechanical support

C ELL W ALL Secondary Cell Wall When the cell is fully grown, it may retain its primary cell wall, sometimes thickening it, or it may deposit new layers of a different material called the secondary cell wall. Functions: Strengthens and waterproofs the wall Renders support and protection
