Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process always involves the movement of materials from inside the cell to outside the cell?
A
difusion
B
exocytosis
C
endocytosis
D
osmosis
Explanation: 

Detailed explanation-1: -Exocytosis (exo = external, cytosis = transport mechanism) is a form of bulk transport in which materials are transported from the inside to the outside of the cell in membrane-bound vesicles that fuse with the plasma membrane.

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 process by which cells move materials from within the cell into the extracellular fluid. Exocytosis occurs when a vesicle fuses with the plasma membrane, allowing its contents to be released outside the cell.

Detailed explanation-4: -Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.

Detailed explanation-5: -Plasma membrane controls the flow of substances in and out of cell.
