Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When cells form a vesicle to release materials, which form of transport is occurring?
A
Endocytosis
B
Exocytosis
C
Facilitated Diffusion
D
Osmosis
Explanation: 

Detailed explanation-1: -Exocytosis is a form of active transport through which large molecules are moved from the interior to the exterior of the cell. Vesicles are packaged within the cell and transported to the cell membrane, where their phospholipid bilayers fuse. This allows the contents to be released outside the cell.

Detailed explanation-2: -Exocytosis is a form of bulk transport during which large numbers of molecules are transported out of the cell. In exocytosis, a vesicle (a small, membrane-bound compartment) containing the molecules to be released fuses with the cell membrane, and the contents of the vesicle are expelled.

Detailed explanation-3: -Exocytosis is the fusion of secretory vesicles with the plasma membrane and results in the discharge of vesicle content into the extracellular space and the incorporation of new proteins and lipids into the plasma membrane.
