  • Lysosomes are membrane-bound organelles which contain acid hydrolases or digestive enzymes that digest excess or worn out organelles, food particles, engulfed viruses or bacteria and macromolecules.
  • Lysosomes are known as polymorphic cellular organelles (they exist in more than one form).
  • A lysosome is autophagic in nature (the cytoplasmic material and organelles are degraded by lysosomes).
  • So, the correct answer is 'They are monomorphic'.
