Question

During endocytosis

• A. The cell divides its cytoplasm during mitosis.
• B. The cell digests itself.
• C. The cell engulfs and internalises materials using its membrane.
• D. The cell enables the extracellular digestion of large molecules.

Answer 1

Answer: (C)

The cell engulfs and internalises materials using its membrane.

An important activity of the plasma membrane of certain cell types is endocytosis. Endocytosis is the process by which material is transported into cells by formation of vesicles. The term includes two essentially similar processes, they are phagocytosis (cell eating) and pinocytosis (cell drinking). Phagocytosis is the bulk ingestion of solid food into the cell while pinocytosis is the ingestion of liquid materials.

So, the correct answer is 'The cell engulfs and internalises materials using its membrane.'
