Which organelle is primarily responsible for providing energy for the cell?

• A. Mitochondria
• B. Ribosomes
• C. Chloroplasts
• D. Golgi apparatus

Answer: (A)

Verified step by step guidance

1. Begin by identifying the function of each organelle listed in the options. Understanding their roles will help determine which one is responsible for energy production.
2. Consider the mitochondria first. They are known as the 'powerhouses' of the cell because they generate ATP (adenosine triphosphate), the cell's main energy currency, through cellular respiration.
3. Next, examine the role of ribosomes. Ribosomes are responsible for protein synthesis, not energy production, so they can be eliminated as the answer.
4. Evaluate chloroplasts. Chloroplasts are involved in photosynthesis, converting light energy into chemical energy in the form of glucose, primarily in plant cells. While they do produce energy, they are not the primary energy source for most cells.
5. Finally, consider the Golgi apparatus. The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell, not in energy production. Therefore, the mitochondria are the organelles primarily responsible for providing energy for the cell.
