Question

Engulfing of solid materials by cells is called

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

Answer 1

The correct option is B Phagocytosis

Pinocytosis is the process of ingestion of liquid into a cell by the budding of small vesicles from the cell membrane. It occurs in many cell types and takes place continuously.

Phagocytosis is a process in which large solid particles, such as cells or cellular debris, are transported into the cell. It is a major mechanism used to remove pathogens and cell debris. It mainly occurs in immune cells and Amoeba through false feet i.e., pseudopodia.

Active transport is the movement of molecules across a membrane from a region of lower concentration to a region of higher concentration, in the direction against the concentration gradient.

Autolysis, more commonly known as self-digestion, refers to the destruction of cells or tissues through the action of their own enzymes.

So, the answer is B.
