What organelle takes up 90% of a plant cell?

Central Vacuole in Plant Cells

The central vacuole is a large membrane-bound organelle found in plant cells. It plays a crucial role in maintaining the structure and functions of the plant cell. In fact, the central vacuole can occupy up to 90% of the total volume of a plant cell.

Functions of the Central Vacuole

The central vacuole acts as a storage organelle, holding a variety of substances such as water, nutrients, waste products, and pigments. It helps maintain the turgidity of the cell, which is essential for plant growth and support.

Importance of the Central Vacuole

The central vacuole also plays a role in regulating cell turgor pressure, storing toxic waste products, and facilitating the transportation of molecules within the cell. Additionally, it contributes to the plant's ability to withstand environmental stresses.
