NEET BIOLOGY

Detailed explanation-1: -The cell wall is located outside the cell membrane. It consists mainly of cellulose and may also contain lignin, which makes it more rigid. The cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting.

Detailed explanation-2: -In a plant cell, a stiff wall surrounds the membrane, giving the cell a rigid, boxlike shape. The cell membrane protects the cell and regulates what substances enter and leave the cell. Most mature plant cells have one large vacuole.

Detailed explanation-3: -Cell wall is a rigid covering present outside the plant cell which is composed of a complex structural substance called cellulose.

Detailed explanation-4: -The strongest component of the cell wall is a carbohydrate called as cellulose, a polymer of glucose. When the additional layer of lignin is added to the primary cell wall a secondary cell wall is formed. Secondary cell wall increases the rigidity and strength of the cell.

Detailed explanation-5: -It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
