Identify the organelles listed in the problem: Central vacuole, Mitochondrion, Chloroplast, and Golgi apparatus.
Recall the primary functions of each organelle: Mitochondrion produces energy, Chloroplast conducts photosynthesis, Golgi apparatus modifies and packages proteins.
Understand that the central vacuole in plant cells is a large, fluid-filled organelle that stores water and other substances.
Recognize that the central vacuole helps maintain turgor pressure by exerting outward pressure on the cell wall when filled with water.
Conclude that the organelle primarily responsible for storing water and maintaining turgor pressure in plant cells is the central vacuole.
