Detailed explanation-1: -Definition. 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-2: -Vacuole helps in storage of salts, minerals, pigments and proteins within the cell. It isolates metabolic waste that might be harmful to the cell. It maintains turgor pressure.

Detailed explanation-3: -The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright.

Detailed explanation-4: -In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.

Detailed explanation-5: -The main functions of vacuoles include maintaining cell acidity and turgor pressure, regulating the storage and transport of substances, controlling the transport and localization of key proteins through the endocytic and lysosomal-vacuolar transport pathways, and responding to biotic and abiotic stresses.
