1
Identify the organelles listed in the problem: chloroplast, mitochondrion, central vacuole, and Golgi apparatus.
Recall the primary functions of each organelle: chloroplasts are involved in photosynthesis, mitochondria generate ATP through cellular respiration, the Golgi apparatus modifies and packages proteins, and the central vacuole stores water and other substances.
Understand that turgor pressure in plant cells is the pressure exerted by stored water inside the cell against the cell wall, which helps maintain cell rigidity and structure.
Recognize that the central vacuole is the organelle responsible for storing water and maintaining turgor pressure in plant cells.
Conclude that among the options given, the central vacuole is the organelle that primarily stores water and helps maintain turgor pressure.
