Which organelle often takes up much of the volume of a plant cell?

Vacuole

A vacuole is a membrane-bound organelle (like a bubble) that is present in all plant cells. Some animal and fungal cells also have vacuoles, but they are much smaller. Most mature plant cells have one large central vacuole that can occupy as much as 80% of the cell volume, making the vacuole the most prominent organelle in plant cells.

A plant cell contains a large vacuole that occupied most of the plant cells; therefore, it helps to position other organelles in the cells. The central vacuole stores water and nutrients and creates turgor pressure to support plants in the upright position.
