How does the cell wall differ from the plasma membrane?

• The cell wall and plasma membrane are the same thing.

• The cell wall is a rigid layer that provides structural support and protection, while the plasma membrane is a selectively permeable barrier that controls the movement of substances.

• The cell wall is a flexible layer that controls the movement of substances, while the plasma membrane provides structural support and protection.

• The cell wall is found in animal cells, while the plasma membrane is found in plant cells.

What is the role of vacuoles in turgor pressure?

• Vacuoles store air instead of water to create turgor pressure.

• Vacuoles store water and other substances to create osmotic pressure for maintaining turgor pressure.

• Vacuoles have no role in maintaining turgor pressure.

• Vacuoles release water to decrease osmotic pressure and reduce turgor pressure.
