Need help with these two:
26. Why do plant cells contain both choroplasts and mitochondria?
a. in the light, plants are photosynthetic autotrophs. In the dark, they are heterotrophs.
b. if plants can't produce enough ATP to make sugars during photosynthesis, they can produce it during cellular respiration
c. Sugars are produced in chloroplasts during photosynthesis. These sugars can be stored in the plan for later use during cellular respiration
d. The leaves, and sometimes, the stems of plants contain chloroplasts while the roots of plants contain mitochondria.
27. Which of the following is true for both aerobic and anaerobic respiration?
a. ATP is produced during glycolysis
b. Pyruvate is broken down to ethanol or lactate
