Question

chloroplasts and mitochondria are both involved in energy conversion in cells and share many similarities. select the two characteristics that apply only to chloroplasts. a contain dna b found in plants c contain pigments d used in photosynthesis e used in aerobic respiration

Explanation:

• Option A: Both chloroplasts and mitochondria contain DNA (endosymbiotic theory), so not unique to chloroplasts.
• Option B: Mitochondria are also found in plant cells, so not unique.
• Option C: Chloroplasts contain pigments like chlorophyll for light absorption; mitochondria lack pigments—unique to chloroplasts.
• Option D: Chloroplasts are the site of photosynthesis; mitochondria do not participate in photosynthesis—unique to chloroplasts.
• Option E: Mitochondria are used in aerobic respiration; chloroplasts are not—unique to mitochondria.

Answer:

C. contain pigments, D. used in photosynthesis
