❓ Quick answer
What is the difference between the cell wall and the cell membrane?
The cell membrane is a thin, flexible layer of lipids and proteins that controls transport in and out of the cell. The cell wall is a rigid structure outside the cell membrane made of cellulose (in plants) that provides structural support and protection.
❓ Quick answer
Why is the vacuole so large in plant cells?
The large vacuole stores water and maintains turgor pressure, keeping the plant cell rigid and upright. It also stores nutrients, pigments, and waste products. When a plant wilts, the vacuole has lost water and turgor pressure decreases.
❓ Quick answer
What is the role of plasmodesmata in plant cells?
Plasmodesmata are channels that pass through cell walls connecting adjacent plant cells. They allow the direct passage of small molecules and proteins between cells, enabling cell-to-cell communication and transport.
