Most mature plant cells contain one large central vacuole encompassed by a membrane called the tonoplast.

At the same time, the cytoplasm develops large vacuoles and forms numerous cytoplasmic masses.

They have large central vacuoles, which allow the cells to store and regulate ions, waste products, and water.

The cytoplasm forms a thin lining between the cell wall and the large vacuole it surrounds.

In addition, they have pairs of large refractive vacuoles, which are found near the flame cells.

The trophozoites are round, have a large vacuole and a large nucleus.

In these cells the cytoplasm forms only a peripheral layer with a large central vacuole.

Lysosomes do not appear to be affected, but there is an appearance of large, empty vacuoles in the cytoplasm.

It is not yet clear how, but special cells with large vacuoles probably play an important role.

The trophozoites are initially tear-shaped and possess a large vacuole.
