Question

Liquid food drinking is called as

• A. Pinocytosis
• B. Phagocytosis
• C. Imbibition
• D. Exocytosis

Answer 1

The correct option is A Pinocytosis

Exocytosis and endocytosis are the processes for active cellular extrusion and intake respectively of such material that cannot pass through the unbroken plasma membrane. Both processes involve movement of folding of the membrane, which are independent on its fluidity and mobility.

Endocytosis is of two types:

1) Pinocytosis: It is a process of intake of droplets of extracellular fluid along with sub-microscopic particles across the cell membrane.

2) Phagocytosis: It is a process of intake of solid particles such as food, foreign particles, pathogens, etc., across the cell membrane by forming detachable vesicles.
