In cell Biology, a vesicle is a small organelle within a cell, consisting of fluid enclosed by a lipid bilayer membrane. Vesicles can form naturally, for example, during the processes of secretion (exocytosis), uptake (phagocytosisand endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes. If there is only one phospholipid bilayer, they are called unilamellar liposome vesicles; otherwise they are called multilamellar. The membrane enclosing the vesicle is also a lamellar phase, similar to that of the plasma membrane, and vesicles can fuse with the plasma membrane to release their contents outside of the cell. Vesicles can also fuse with otherorganelles within the cell.
What else can I help you with?
What are the stages of endocytosis?
Endocytosis involves three main stages: initiation, vesicle formation, and vesicle fusion. In the initiation stage, the cell membrane invaginates to form a pocket around the target molecule. During vesicle formation, the pocket pinches off to form a vesicle containing the target molecule. Finally, the vesicle fuses with intracellular compartments to deliver its cargo.
Which of these processes brings in large macromolecules and particles by the formation of a vesicle in the outer membrane?
Endocytosis is the process that brings in large macromolecules and particles by the formation of a vesicle in the outer membrane. This includes phagocytosis for solid particles and pinocytosis for liquid particles.
Is Golgi found in plants animals or both?
Both. Golgi is essential for vesicle formation
A characteristic of plasma membranes that helps them fuse during vesicle formation and phagocytosis is the?
The capacity of lipids to associate and maintain a bilayer organization is a characteristic of plasma membranes that helps them fuse during vesicle formation and phagocytosis. The plasma membrane is also known as the cell membrane.
Is vesicle-aided transport out of the cell?
Yes, vesicle-aided transport is a process by which substances are moved out of the cell through the formation and fusion of vesicles with the cell membrane. These vesicles can contain molecules destined for secretion or removal from the cell.

Movement of large molecules by formation of a vesicle?
This process is called endocytosis. It involves the ingestion of large molecules or particles by the cell through the formation of a vesicle. The vesicle is formed when the cell membrane engulfs the material to be transported, creating a membrane-bound sac within the cell.

What does the golgi body have a major role in?
The modification of proteins and shipping said proteins to their destinations in and out of the cell. Vesicle manufacture for various reasons. Could go into this much deeper but I think you would not need information on clathrin proteins and vesicle formation.
differentiate endocytosis from exocytosis?
Endocytosis:- It is the process by which cells take up substance from the external environment. In this a vesicle called endocytic vesicles get formed around the foreign substances. It occurs due to both phagocytosis and pinocytosis. In this internal vesicles are formed that are like phagosomes are formed The best known example is formation of food vacuole in amoeba. It is not involved in cell wall formation It involves transportation of macromolecules into the cell. At the end of this process the vesicle fuses with the membrane bound organelles. Exocytosis:- It is the process by which cells give up substance to the external environment. In this the vesicle that is filled with water gets fused with plasma membrane. It occurs due to regulated secretory pathways. The vesicle that is secretory in nature gets formed. The best known example is the hormone release. It is involved in cell wall formation. It is involved in transportation of macromolecules out of the cell. At the end of this process the vesicle gets connected with the cell membrane.
What is the vesicular formation membrane bound sac called?
These are called vesicles and they transport various substance into the cell and out of the cell.
what substance would be found in a vesicle?
Enzymes might be found inside a vesicle.
How do you use the word vesicle in a sentence?
A vesicle is a small fluid-filled sac.
What happens to vesicle in exocytosis?
The vesicle fuses with the cell membrane, releasing it's contents.
