Vesicles are formed from various organelles, primarily the endoplasmic reticulum (ER) and the Golgi apparatus. The ER is responsible for synthesizing proteins and lipids, which can be packaged into vesicles for transport. The Golgi apparatus then modifies these molecules and further packages them into vesicles for secretion or delivery to other cellular compartments. Additionally, lysosomes and peroxisomes can also be considered specialized vesicles involved in digestion and metabolic processes.
What else can I help you with?
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.
Cells contain smaller parts known as organelles. The nucleus, chloroplasts, mitochondria, and vacuoles are all examples of organelles. What do these organelles have in common?
They are all enclosed by a membrane.
What are the organelles known as demolition squads?
The organelles known as demolition squads are the lysosomes. They break down waste materials and cellular debris. They are described as the 'stomach' of the cell by some.
Specialized cells have no organs?
Specialized cells that have no organelles are known as Prokaryotes.
What does the sperm made vesicle do?
The sperm vesicle, also known as the acrosome, contains enzymes that help the sperm penetrate the outer membrane of the egg during fertilization. It plays a crucial role in allowing the sperm to access and fuse with the egg to initiate the process of fertilization.
Cells have particular structures that perform specific jobs These structures are known as what?
organelles

What is the Translation of gallbladder?
The gallbladder is also known as the biliary vesicle or cholecyst, or in latin, the vesica fellea.
Can two vesicles fuse?
Yes, two vesicles can fuse together through a process known as membrane fusion. This is a vital process that occurs in cells to transport molecules between organelles or between the cell and its environment. During fusion, the lipid bilayers of the vesicles merge to form a single compartment, allowing their contents to mix.

What organelles are also known as digestive bags?
Lysosomes

What is the tiny structures in protoplasm known as little organ?
Organelles
Which cell organelles are known as the storage units in the cells?
Vacuoles
What is formed when part of the cell membrane pinches off?
When part of the cell membrane pinches off, it forms a small vesicle called an endocytic vesicle. This process is known as endocytosis and allows the cell to engulf and internalize molecules or particles from its external environment.
Specialized cells have no organs?
Specialized cells that have no organelles are known as Prokaryotes.
