Suara.com – Vacuole is a cavity inside cell lined with a membrane and filled with fluid or called cell fluid. Then, what the function of the vacuole in plants?
There are two types of vacuoles, namely vacuoles in plant and animals. However, on this occasion Suara.com will discuss about vacuole function on plants.
Excerpted from the book ‘Cell Biology’, which was written by Hafidha Asni Akmalia, S.Pd., M.Sc., when viewed from a light microscope, the vacuole looks like an empty and transparent space. That’s what makes this organelle named vacuole which is taken from another language which means empty.
The first vacuole was discovered in Protozoa by Lazzaro Spallanzani. Then another scientist named Mathias Schleiden researched plant cells and found that vacuoles are not as respiration, as was originally thought when found in Protozoa.

The size of the vacuole is quite large, it can take up about 95 percent of the protoplast. In higher plants there are around 60 percent or more.
Vacuole Development in Plant Cells
Vacuoles in young cells are observed to originate from small filaments, which then coalesce and enlarge as the cell grows. The filaments are numerous and will swell and then fuse with each other to form a large central vacuole.
Under certain physiological conditions, vacuoles can experience a reversed pattern of development but will re-unite as before.
The vacuole in the tentacle cells of the carnivorous plant Drosera rotundifolia, which is completely filled with anthocyanins, can undergo rupture when there is a trapped attack.

Plant vacuoles can also originate from the Endoplasmic Reticulum. Endosperm cells of wheat, corn and rice plants detected the presence of Endoplasmic Reticulum bodies containing proteins.
