Which of the following is a similarity between mitochondria and chloroplasts?

• A. Both organelles contain chlorophyll.
• B. Both organelles are responsible for cellular respiration.
• C. Both organelles are found in animal cells.
• D. Both organelles are involved in energy conversion processes.

Answer: (D)

Verified step by step guidance

1. Begin by identifying the primary functions of mitochondria and chloroplasts. Mitochondria are known for their role in cellular respiration, converting glucose into ATP, the energy currency of the cell. Chloroplasts are involved in photosynthesis, converting light energy into chemical energy stored in glucose.
2. Understand that both mitochondria and chloroplasts are involved in energy conversion processes, albeit in different ways. Mitochondria convert chemical energy from nutrients into ATP, while chloroplasts convert light energy into chemical energy.
3. Recognize that both organelles have their own DNA and are thought to have originated from endosymbiotic events, where early eukaryotic cells engulfed prokaryotic cells, leading to a symbiotic relationship.
4. Note that chlorophyll is a pigment found in chloroplasts, not mitochondria. Chlorophyll is essential for capturing light energy during photosynthesis.
5. Clarify that mitochondria are found in both animal and plant cells, whereas chloroplasts are primarily found in plant cells and some protists. This distinction highlights their different roles in energy conversion within various types of cells.
