Question

Taking in of food particles or foreign bodies through cell membrane is

• A. Phagocytosis
• B. Pinocytosis
• C. Osmosis
• D. Active transport.

Answer 1

The correct option is A Phagocytosis

A. Phagocytosis is a process by which a cell engulfs a solid particle by forming an internal compartment known as a phagosome.

B. Pinocytosis (fluid endocytosis or bulk-phase pinocytosis) is a form of endocytosis in which extracellular fluid or liquid is engulfed and are brought into a cell by the budding of small vesicles on the surface.

C. Osmosis is the process by which solvent molecules move across the selectively permeable membrane into a region of higher solute concentration.

D. Active transport is a process by which molecules move across the cell membrane from a region of low concentration to a region of high concentration against the concentration gradient using energy.

So, the correct answer is 'Phagocytosis'.
