Taking in of solid particle by cell is called:
Correct answer: A. Phagocytosis
- A. Phagocytosis
- B. Pinocytosis
- C. Exocytosis
- D. Endocytosis
Explanation
Phagocytosis is the process by which a cell uses its plasma membrane to engulf a large solid particle, giving rise to an internal compartment called the phagosome. It is one type of endocytosis, while pinocytosis, otherwise known as fluid endocytosis, is a mode of endocytosis in which small particles suspended in extracellular fluid are brought into the cell through an invagination of the cell membrane, resulting in a suspension of the particles within a small vesicle inside the cell.
