Mention a single membrane bound organelle which is rich in hydrolytic enzymes.

Lysosomes are the single membrane bound organelle which is rich in hydrolytic enzymes.They are formed by Golgi apparatus. The isolated lysosomal vesicles have been found to be very rich in almost all types of hydrolytic enzymes (hydrolases – lipases, proteases, carbohydrases) optimally active at the acidic pH.
