• A. Mitochondria
• B. Endoplasmic Reticulum
• C. Golgi complex
• D. Lysosomes

Answer 1

The correct option is A

Mitochondria

The correct option is A.

Explanation of the correct option:

1. Mitochondria is the powerhouse of cells that are generally involved in the production of energy currency ATP.
2. All the cells require energy to live and therefore mitochondria are found in all the living cells whether plants or animals.
3. Since mitochondria are found in both plants and animals.
4. The number of mitochondria in a cell is also dependent on how much energy that cell normally requires.
5. For example, muscle cells that are involved in locomotion or lifting weights will normally require more energy and more ATP than a skin cell.

Explanation of the incorrect options:

Option B:

The endoplasmic reticulum can be either smooth or rough and does the function of protein formation.

Option C:

Golgi bodies are factories in which the proteins received from the endoplasmic reticulum are then processed and sorted for transport to their places like lysosomes, the plasma membrane, or secretion.

Option D:

1. Lysosomes are membrane-bound organelles and the area within their membrane is known as the lumen, which generally contains hydrolytic enzymes and other cellular debris.
2. The key function of the lysosomes is the digestion & removal of waste.

Final Answer: Mitochondria are called the powerhouse of the cell.
