Final answer:
The central vacuole in plants is primarily involved in storage of water and nutrients. It regulates the cell's concentration of water and stores water and nutrients. When water levels in the soil become low, water moves out of the central vacuoles and cytoplasm, causing wilting.
Step-by-step explanation:
The central vacuole in plants is primarily involved in storage of water and nutrients. The central vacuole plays a key role in regulating the cell's concentration of water in changing environmental conditions. It stores water and nutrients, and when the water concentration in the soil becomes lower than in the plant, water moves out of the central vacuoles and cytoplasm, resulting in wilting.
