The membrane around the vacuole is known as

The tonoplast is a special membrane that surrounds the vacuole in plant cells. This membrane controls what goes in and out of the vacuole. It acts like a gatekeeper for the cell storage space.

Vacuoles are large fluid-filled sacs that store water, nutrients, and waste in plant cells. The tonoplast keeps these materials separate from the rest of the cell. This separation helps the cell stay organized and work properly.

Elaioplast and amyloplast are types of plastids that store oils and starch. Cytoplast is not a common term in cell biology. Only tonoplast specifically refers to the vacuole membrane.
