The Golgi apparatus
D
The mitochondrion
Verified step by step guidance1
Understand that turgor pressure in plant cells is the pressure exerted by the cell contents against the cell wall, which helps maintain the cell's shape and rigidity.
Identify the organelle responsible for storing water and solutes, which swells as it fills with water, thereby generating turgor pressure.
Recall that the central vacuole is a large, membrane-bound compartment in plant cells that stores water and other substances.
Recognize that as the central vacuole fills with water, it expands and pushes the plasma membrane against the cell wall, creating turgor pressure.
Conclude that the central vacuole is the structure that helps maintain cell shape by generating turgor pressure in plant cells.
