Question

briefly describe the structure and function of cell wall

Answer 1

Hi........

The plant cell wall is composed of cellulose.Cellulose.It is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure. The plant cell wall consists of three layers. Each layer has its own unique structure and function.
Its functions are -Gives the cell a definite shape and structure.Provides structural support.Protection against infection and mechanical stress.Separates interior of the cell from the outer environment.It enables transport of substances and information from the cell insides to the exterior and vice versa.Also helps in osmotic-regulation.Prevents water loss.The physiological and biochemical activity of the cell wall helps in cell-cell communication.It prevents the cell from rupturing due to tugor pressure.Aids in diffusion of gases in and out of the cell. Also provides mechanical protection from insects and pathogens.

Answer 2

HERE IS YOUR ANSWER....

Function:- The cell wall gives the plant its actual shape. It acts as a gatekeeper, because it determines what can come in and out of the cell in order to keep the cell protected. It is kind of like the outside bricks of a castle, only, as you will learn as you read on, there are holes throughout this castle. Those holes do make the cell vulnerable, but they are important to the function of the cell.
Structure:- Cellulose is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure. The plant cell wall consists of three layers. Each layer has its own unique structure and function. The layers may vary depending on the type of plant and its needs.
