Question

The cell's "garbage disposals" are the

• A. lysosomes
• B. peroxisomes
• C. mitochondria
• D. vacuoles

Answer 1

The correct option is A

lysosomes

The correct option is A

Explanation of the correct option:

1. Lysosomes are cell organelles that contain digestive enzymes capable of breaking down all organic materials.
2. In case of any damage to the cell, lysosomes burst and release the enzymes which digest the other cell organelles and finally the whole cell. So, they are called "suicide bags".
3. Lysosomes are small membrane-bounded organelles that contain hydrolytic enzymes.
4. Lysosomes digest the old or dead organelle and foreign particles and are thus called garbage disposals of the cell.

Explanation of the incorrect option:

Option B:

1. Peroxisome does oxidation of biomolecules and helps in membrane synthesis.

Option C:

1. Mitochondria are also known as the powerhouses of the cell because here energy-rich compound ATP or adenosine triphosphate is produced which is required by the body to carry out various metabolic activities.

Option D:

1. Vacuoles maintain a water balance in the cell.
2. Vacuole stores primary metabolites salts, minerals, pigments, and proteins within the cell.
3. Vacuoles are involved in the breakdown of organelles and macromolecules, therefore facilitating the recycling of chemical elements within the cell.

Final answer: The cell's "garbage disposals" are the lysosomes.
