Dear Student,
The vacuole is an organelle that is composed of a semi-permeable membrane that changes shape and size based on the needs of the cell. The vacuole in both plant and animal cells also functions as a waste receptacle, keeping harmful molecules separate from the cell’s interior. In addition, it works to store organic and non-organic molecules as well as break down extremely complex molecules.
If a cell did not have a vacuole, it would be unable to carry out its usual functions and would eventually die. In plants, the vacuole plays an important role in water storage and the maintenance of structure. In animals, the vacuole is much smaller, but also performs essential functions related to protection of the cell, isolation of waste products and more. Vacuoles are also present in fungi and bacteria
Regards.
