Question

When a lysosome fuses with a phagosome, it results in the formation of

• A. Primary lysosome
• B. Secondary lysosomes
• C. Residual body
• D. Autophagic vacuole

Answer 1

The correct option is B Secondary lysosomes

Lysosomes show polymorphisms because of their different shape and functions. Primary lysosomes are newly formed lysosomes. when the primary lysosomes fused with phagosomes, heterolysosomes or digestive vacuoles or hetero phagosomes are formed, Residual lysosome (lysosomes having undigested materials), autophagic vacuoles (perform autophagy). Digestive vacuoles, autophagic vacuoles and residual vacuoles are together called secondary lysosomes.
