Identification of Organelles with Hydrolases

1. Break Down the Problem
   We need to identify which of the following organelles contains approximately fifty different types of hydrolases:

   • Mitochondria
   • Plasma membranes
   • Lysosomes

2. Relevant Concepts
   Hydrolases are enzymes that catalyze the hydrolysis of various bonds. Lysosomes are known as the "suicide bags" of the cell due to their role in breaking down waste materials. They contain a variety of enzymes, particularly hydrolases.

3. Analysis and Detail

   • Mitochondria: Primarily involved in energy production through aerobic respiration, they contain only a few specific enzymes.
   • Plasma membranes: Mainly serve as barriers, contain proteins and lipids but do not contain hydrolases.
   • Lysosomes: Contain a large variety of hydrolases (around 50 different types) that are vital for degrading macromolecules.

4. Verify and Summarize
   The function and composition of each organelle point to lysosomes as the primary source of hydrolases.

Final Answer

The organelle that contains approximately fifty different kinds of hydrolases is Lysosomes.
