I had been asked this question in homework.

My question is based upon Organelles in Eukaryotic and Prokaryotic Cells in section Cell : The Unit of Life of Biology – Class 11

Answer 1

Correct choice is (a) These are membrane bound vesicles that contain digestive enzymes

The explanation is: Lysosomes are membrane bound vesicles that contain digestive enzymes. They are single membraned and are isolated from their neighboring environment. The digestive enzymes present include proteases, lipases, nucleases, glycosidases and phosphatases. The lysosomes defend against bacterial and viral infection.
