Question

Secondary lysosomes are

• A. Digestive vacuoles
• B. Autophagic vacuoles
• C. Residual vacuoles
• D. All of the above

Answer 1

The correct option is D All of the above

• The fusion of a primary lysosome with a phagosome forms a secondary lysosome which is activated and takes part in the digestion process.

A. Digestive vacuoles- helps in digestion and excretion, food particles pinch away from these vacuoles into small vesicles and the vacuole fuses with the cell membrane to release the waste products.

B. Autophagic vacuoles- is membrane-bound vacuole which contains intracellular material to be digested.

C. Residual vacuole- is vesicles that contain indigestible materials.

• All the above vacuoles are a type of secondary lysosomes.
  
• So, the correct answer is 'All of the above'.
