Do Plant Cells Have A Permanent Vacuole? Learn About Its Role Here

Do Plant Cells Have A Permanent Vacuole

A vacuole might be misinterpreted as a practically useless vacuum. In reality, nature doesn’t leave things to sit idle. Hence, a vacuole is an essential element in the intracellular environment of a plant cell with its unique functions to carry and responsibilities to fulfill.

So, do plant cells come with a permanent vacuole? Yes, they do! But before we go more into details, let’s first discuss-

What Is A Plant Cell Vacuole

What Is A Plant Cell Vacuole

The vacuole is a somewhat spherical, membrane-bound cellular organelle. Plant cell vacuoles are significantly larger than that of animal cells and can be large enough to occupy the major central portion of the cell. 

It helps push the remaining organelles to the periphery. The function of plant cell vacuole is lysosomal.

Are There Permanent Vacuole in Plant Cells?

Do Plant Cells Have A Permanent Vacuole

Indeed, plant cells are one of the only ones to have permanent vacuoles due to their assigned functions of storage and metabolism. Contrarily, animal cells have small, peripherally placed vacuoles that function temporarily, only under certain requirements.

What Is The Use Of Vacuole In A Plant Cell

The great size of the vacuole implies its manifold purpose in the cell, some of which can be demonstrated in the following discussion:


The lysosome is an enzyme-filled pocket that is membrane-bound and occasionally releases hydrolytic enzymes to carry out catabolic metabolism of the cell as well as phagocytosis. Plant vacuole functions similarly to a lysosome in such a way that it is considered the trash chute of a cell. 

Vacuole takes up metabolic waste products, processes those wastes, and finally excretes them. The fact that it rids intracellular water in this way signifies the maintenance of water balance and heat regulation through the vacuole.

Detoxification and metabolism

Vacuoles take up toxic substances and handle them to prevent their detrimental effects on the plant body. Toxic chemicals or biological components that make their way into the cell are usually converted into more soluble, safer compounds. They are then either excreted or made inactivated to minimize their harm.

Vacuoles are the metabolic unit of plant cells as it regulates anabolism and catabolism. Furthermore, they retain the end products of metabolism, such as pigment, ions, salts, minerals, and organic constituents.

Structural integrity

Vacuoles are an essential component in maintaining the structural integrity of a cell by exerting centrifugal pressure from the center toward the cell wall. This enables the cell to become significantly larger without the necessity to synthesize more amount of structural materials.

The vacuole also influences the import and export of salts and salts. Thus regulating the osmotic gradient across the cell wall that dictates the movement of water in both directions.


Plant vacuole is capable of taking and releasing fluid depending on the physiological condition of the cell. The turgor pressure of the cell is controlled by this organelle. When there is excess fluid permeating through the cell wall, the vacuole takes up the fluid and swells up to the brim.

The opposite happens in dehydration, where the vacuole loses water to make up for the water demand of the plant. That is when wilting and necrosis takes place, as we see in neglected house plants.


As hinted above, the storage of metabolic end-products the products are also of great importance. For example, human beings are benefitted from using rubber, gum, opioids, honey antiseptic, and medicinal items extracted from plants, which are practically the chief stored products of the vacuole.

Pigment makes the plant more attractive, making it more susceptible to vector-based pollination. Bitter or harsh materials are used to protect the plants from external invasion.  

What’s The Function Of Permanent Vacuole In A Plant Cell

The permanent vacuole of a plant cell carries out some functions that are specific to this organelle, not possible to be achieved by other substitutes, such as:

Storage of cell sap

As already mentioned, the vacuole of a plant cell is specialized to store a variety of substances, it also acts to store cell sap. Cell sap is little pockets filled with liquids that are storehouse to the storage materials in question.

The cell sap of a permanent vacuole not only provides structural integrity to the cell but also mobilizes ions and molecules whenever required.

Xylem formation

Xylem is one of the transport tissues of plants that carry raw materials for food synthesis from roots to the leaves. This xylem system is formed from the meristematic cells (cambium and pericambium). 

The vacuoles of the pluripotent cells that form these elements bind together to form the xylem system. Therefore, a permanent vacuole plays an important role in ion transport as well.

Can You Find Vacuole In All Plant Cells

Vacuole must be present in all living cells for it to be able to carry out cellular functions. Since the cells of cambium, capillary, and sieve cells are living, they all have vacuoles.

The only dead cells of a plant are the xylem. After its formation, the xylem loses its protoplasm and cell membrane. The xylem cells remain in close contact with one another without any distinct boundary. Since the loss of protoplasm is equivalent to death in plant cells, the xylem is considered dead. 

Hence, all plant cells except for xylem cells have vacuoles. If the vacuoles were to be lost or degraded due to any cause, the cells would eventually die from unregulated ion and water balance.


The vacuole is an intramembranous intracellular organelle found in the cells of plants and fungi. They are designated to carry out functions that are indispensable for life. Without the aid of vacuoles, plant cells could not flourish. 

Vacuoles differ from cell to cell within the same plant to execute tasks particular to that cell and might vary greatly in morphology and life span. However, the core purpose of protecting the anatomy and physiology of the plant remains the same for all types of vacuoles.
