TRANSPORT VESICLE Meaning and
Definition
-
A transport vesicle refers to a specialized membrane-bound sac or vesicle within a cell responsible for transporting molecules, macromolecules, or particles from one compartment or organelle to another. These vesicles play a fundamental role in maintaining the proper functioning and organization of the cell, ensuring the delivery of essential cargo across different cellular compartments.
Transport vesicles can be classified into various types, each serving different purposes within the cell. One common type is the secretory vesicle, which is involved in the release of proteins, hormones, enzymes, or other biomolecules from the cell. Another type is endocytic vesicles, responsible for internalizing substances from the extracellular environment into the cell.
These vesicles form through a process known as vesicle budding, where a small portion of the membrane pinches off from the donor organelle, enclosing the cargo destined for transport. The vesicle then undergoes movement along cytoskeletal tracks, such as microtubules or actin filaments, powered by motor proteins, ensuring precise and directed transport to the target organelle.
Upon reaching their destination, transport vesicles undergo fusion with the target membrane, enabling the release of the cargo into the desired compartment. This fusion process is facilitated by a series of molecular interactions between specific proteins present on both the vesicle and the target membranes.
Overall, transport vesicles are crucial components of cellular transport machinery, ensuring the efficient and regulated trafficking of molecules within a cell, maintaining cellular homeostasis, and enabling proper communication and functionality between different organelles.

Etymology of TRANSPORT VESICLE
The word "transport" originates from the Latin word "transportare", which is a combination of the prefix "trans-" meaning "across" or "beyond" and the verb "portare" meaning "to carry". "Vesicle", on the other hand, comes from the Latin word "vesicula", meaning "small bladder" or "small sac".
In the context of biology, a transport vesicle refers to a small membrane-bound sac that transports substances such as proteins or lipids within a cell or between different cellular compartments. The term "transport vesicle" is derived from the combination of the Latin root "transportare" and the word "vesicle", reflecting its function of carrying or transporting molecules.
