Main Difference

The main difference between Vesicle and Vacuole is that Vesicle made to store many different kinds of molecules, whereas Vacuole is one of the kinds of a vesicle, store mostly water.

Vesicle vs. Vacuole

A vesicle is known as a membrane-enclosed small organelle that is present inside the cell, and it consists of many different types of fluid; on the other hand, a vacuole known as a type of vesicles which mostly consists of water. A vesicle is usually small in size, while a vacuole is relatively larger as compared to the vesicle.

A vesicle is present in all eukaryotic cells; on the contrary, the vacuole is present in both prokaryotic and eukaryotic cells. A vesicle made up of many nutrients, enzymes, water, wastes, harmful compounds, and ions; on the flip side, the vacuole mainly made up of water.

The main role of vesicle is that it is involved in breakdown, temporary storage of food substances and enzymes, buoyancy control and transport molecules to different parts of the cell, and they also serve as a chemical reaction chamber; on the other hand, the main role of vacuole is that it is involved in storing of many substances containing mostly water, and it contributes into the structural support of the cell.

Many different types of vesicles include lysosomes, vacuoles, secretory vesicles, transport vesicles, and extracellular vesicles; on the other hand, many fungi, bacteria, plant, and animal cells consist of vacuoles. There is a present a higher number of the vesicle is present in a cell; on the contrary, the number of vacuoles presents inside a cell is relatively lower than the number of vesicles present inside a cell.

What is Vesicle?

A membrane-bounded organelle that is present inside the cells containing many types of constituents is known as a vesicle. Vesicle contains different types of fluid, and they formed during exocytosis and endocytosis. Liposomes, on the other hand, are formed artificially.

The membrane is a phospholipid bilayer, which usually encloses the vesicle. The unilamellar liposomes consist of a single phospholipid bilayer that surrounds the vesicle. The multilamellar liposomes are generally surrounded by mainly two phospholipid bilayers.

The vesicle becomes fuse with the cell membrane in addition to the organelles present in the cell to release their contents. Many various types of vesicles are present in the cell. A vesicle is involved in breakdown, temporary storage of food substances and enzymes, buoyancy control, and transport molecules to different parts of the cell, and they also serve as a chemical reaction chamber.

Types of Vesicle and Their Function

  • Vacuoles: A large vacuole present in the center of the plant cell is a characteristic feature. It mostly consists of water which controls the osmotic balance of the plant cell and mainly assists as storage of many nutrients.
  • Lysosomes: It is a vital type of vesicle which is involved in the digestion. Many food vacuoles become fuse with lysosomes, which consists of enzymes to digest the food particles.
  • Transport Vesicles: They contribute to the molecular ways present between the locations inside the cell. For example, they transport proteins from RER to the Golgi apparatus.

What is Vacuole?

A type of vesicle that mostly consists of water and a characteristic feature of a plant cell as well as in animal cells, bacterial cells, fungal cells, and in some protists is known as the vacuole. Vacuole consists of many organic compounds other than water, such as enzymes and inorganic compounds.

Due to the fusion of many multiple vesicles, the vacuole formed. The shape and the size of vacuole fluctuate reliant on the requirement of the cell. The function of the vacuole also varies according to the type of the cell, which consists of the vacuole.

Functions of Vacuole

Many major functions of the vacuole are Storing water in plants, Isolating harmful materials to the cells, Regulating internal turgor pressure, Regulating internal pH, Storing small molecules, Storing waste products temporary and exporting them when needed, Supporting structural rigidity in plant cells, Storing proteins which are required by germination, and Increasing the size quickly by just using water.

Types of Vacuole

Different types of vacuole are Bacterial Vacuoles, Plant Vacuoles, Fungi Vacuoles, and Animal Vacuoles.

Key Differences

  1. A vesicle is known as a small, chemically neutral, membrane-bounded, and a temporary container as well, which used to pass its contents across organelles and cell plasma membranes. In contrast, a vacuole is larger, a membranous bound organelle, found in plant and fungal cells, and many bacterial, animal, and protist cells.
  2. The size of the vesicle is small as compared to the vacuole, which is comparatively larger.
  3. The vesicle is found only in eukaryotic cells, while both prokaryotic and eukaryotic cells consist of the vacuole.
  4. Many nutrient molecules, enzymes, water, wastes, harmful substances, and many ions compose the vesicles; on the other hand, water is the main component that composes the vacuole.
  5. The number of vesicles present in a cell is higher as compared to the number of vacuoles present in a cell because they are present in a lower number.
  6. Vesicle is mainly involved in temporary loading of food and enzymes, buoyancy control, transport of the molecules, metabolism, and also in the chemical reaction compartments; on the flip side, vacuole is mainly involved in the structural supporting of the cell, and as well as in the storing of water and many other substances.
  7. Different most common types of the vesicle are transport vesicles, secretory vesicles, extracellular vesicles, vacuoles, and lysosomes; however, many bacteria, fungi, plant and animal cells contain vacuoles.

Conclusion

The above discussion concludes that the Vesicle is involved in the temporary storage of enzymes and food, metabolism, and serves as a chemical reaction chamber for many digestive reactions, while Vacuole is involved in the structural support of the cell. A Vesicle is small in size, whereas Vacuole is relatively larger.
