Meaning of Vacuole

What is Vacuole:

vacuole is a plant cell organelle, although it can eventually be seen in prokaryotic cells. The vacuoles are formed from the integration of numerous membranous vesicles, until they acquire a shape according to the needs of the cell in question.

In turn, during the first stage of plant cell development, numerous vacuoles are formed which, as the cell grows, coalesce or fuse to form a single one. This vacuole occupies most of the space and can corner the cytoplasm against the cell wall.

The vacuoles normally house various fluids, among which water and enzymes stand out and, eventually, they can contain solids such as proteins, salts or sugars. To ensure the containment of these elements, the vacuole is lined with a plasma membrane.


Functions of the vacuoles

Among many of their elementary functions, vacuoles perform the following tasks:

  • Turgor pressure: the cells swell thanks to the vacuoles, which increases the greenish color, in order to regulate transpiration.
  • Centers of degradation: the vacuoles favor the degradation of molecules.
  • Storage of substances: vacuoles act as storage centers for substances, such as sugar and proteins.
