Which of the following is the best explanation for the presence of both chloroplasts and mitochondria in plant cells?
a, in the light, plants are photosynthetic autotrophs. In the dark, they are heterotrophs.
b. if plants cannot produce enough ATP in the process of photosynthese to meet their energy needs, they can produce it in aerobic respiration
c. sugars are produced in chloroplasts. these sugars can be stored in the plant for later use, converted to other chemicals, or broken down in aerobic respiration to yield ATP for the plant to use to meet its energy needs
d. the leaves and sometimes the stems of plants contain chloroplasts which produce APT to meet the energy needs of these plant parts. The roots of plants contain mitochondria which produce ATP to meet the energy of these plant parts.
Answer: c. sugars are produced in chloroplasts. these sugars can be stored in the plant for later use, converted to other chemicals, or broken down in aerobic respiration to yield ATP for the plant to use to meet its energy needs
