How are chloroplasts similar to mitochondria?

• A. Both organelles are responsible for photosynthesis.
• B. Both organelles contain their own DNA and ribosomes.
• 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. Understand the primary functions of chloroplasts and mitochondria: Chloroplasts are involved in photosynthesis, converting light energy into chemical energy stored in glucose, while mitochondria are involved in cellular respiration, converting chemical energy from glucose into ATP.
2. Recognize that both chloroplasts and mitochondria are involved in energy conversion processes, albeit in different ways: chloroplasts convert solar energy into chemical energy, and mitochondria convert chemical energy into a form usable by the cell (ATP).
3. Identify that both organelles contain their own DNA and ribosomes, which is a similarity indicating their evolutionary origins and ability to produce some of their own proteins independently of the cell's nuclear DNA.
4. Clarify that chloroplasts are not found in animal cells, which distinguishes them from mitochondria, as mitochondria are present in both plant and animal cells.
5. Conclude that the correct similarity between chloroplasts and mitochondria is their role in energy conversion processes, with chloroplasts focusing on photosynthesis and mitochondria on cellular respiration.
