Question

This process involves the lysosome fusing with a damaged organelle to recycle it

Mitosis

Endocytosis

Phagocytosis

Autophagy

Answer 1

The correct answer is autophagy.

Autophagy occurs in embryonic development and is also an important process during apoptosis (programmed cell death). The damaged organelle is surrounded by a layer of cytoplasm. This results in the formation of a vesicle called as autophagosome. This vesicle fuses with the lysosome. The contents of lysosome digest the damaged organelle.

Mitosis cannot be the correct option because it is a process of cellular division

Endocytosis cannot be the correct option because it involves the uptake of material from outside the cell which are then digested by lysosomal action.

Phagocytosis cannot be the correct option because it involves the uptake of extracellular particles (by phagocytic cells) such as bacteria which are then digested by lysosomal action.
