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:

1. Analyze Option A: Both chloroplasts and mitochondria contain DNA, so this is not unique to chloroplasts.
2. Analyze Option B: Mitochondria are found in both plant and animal cells, while chloroplasts are mainly in plants, but this is not a unique function - related characteristic of chloroplasts.
3. Analyze Option C: Chloroplasts contain pigments (like chlorophyll) for photosynthesis, mitochondria do not have these pigments. This is unique to chloroplasts.
4. Analyze Option D: Chloroplasts are the site of photosynthesis, mitochondria are for respiration. So "used in photosynthesis" is unique to chloroplasts.
5. Analyze Option E: Mitochondria are used in aerobic respiration, chloroplasts are not. So this is for mitochondria, not chloroplasts.

Answer:

C. contain pigments, D. used in photosynthesis
