Vesicle.
I believe you're talking about a vesicle (likely a transport vesicle). They're basically sacs of membrane.
vesicles
All eukaryotic cells have membrane-covered compartments called vesicles that form when part of the cell membrane envelops an object or substance and then pinches off to transport molecules within the cell or to the cell membrane.
All eukaryotic cells have membrane covered compartments called vesicles. They form when part of the cell membrane of an object pinches off.
Vesicles
The membrane-covered compartment of eukaryotic cells are called vesicles. The vesicles are developed when a part of the membrane nips off.
These membrane bound structures are called organelles.
Its the vesicle/transport vacuole.
All eukaryotic cells have a membrane covered compartment called the nucleus. The nucleus is the control center of the cell and contains the cells DNA.
Eukaryotic cells have membrane-covered compartments that form through a process called endocytosis. This occurs when a portion of the cell membrane surrounds an object, such as a particle or molecule, and pinches off to form a vesicle inside the cell. This vesicle then transports the object into the cell for further processing.
That is called a vacuole.
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.
