Detailed explanation-1: -The vacuole is the cell organelle that stores excess water and gives support and rigidity to a plant cell. It occupies about 80% of the plant cell volume.

Detailed explanation-2: -A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

Detailed explanation-3: -Among its roles in plant cell function, the central vacuole stores salts, minerals, nutrients, proteins, pigments, helps in plant growth, and plays an important structural role for the plant.

Detailed explanation-4: -The central vacuole stores water and maintains turgor pressure in a plant cell. It also pushes the contents of the cell toward the cell membrane, which allows the plant cells to take in more light energy for making food through photosynthesis.

Detailed explanation-5: -However vacuoles are generally said to store water because they generally make up 30% to 80%2 of the plant cell. Thus the cytoplasm, vacuole and all other organelles contain water and contribute to the cells water potential and turgor pressure.
