Detailed explanation-1: -A vacuole is a sphere filled with the fluid and the molecules inside a cell. The central vacuole stores the water and maintains the turgor pressure in a plant cell.
Detailed explanation-2: -Vacuoles-Simply put, vacuoles are storage tanks of the cell. Plant cells have one (1) Large Central Vacuole. Animal cells have a few small vacuoles or none at all. Vacuoles store primarily water, food and waste material.
Detailed explanation-3: -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-4: -In a plant cell, the central vacuole stores water and regulates turgor pressure. Additionally, it forces the cell’s contents toward the membrane, enabling plant cells to absorb more light energy for photosynthesis, the process of turning sunlight into food.
Detailed explanation-5: -Vacuoles are storage organelles, and those in plant cells enable them to attain a large size without accumulating the bulk that would make metabolism difficult.
