Question

Plants use photosynthesis to:

a) store chemical energy and they use cellular respiration to harvest energy.

b) obtain CO2

c) store as well as harvest chemical energy

d) harvest chemical energy and use celular respiration to store chemical energy.

Answer 1

Plants use photosynthesis to- a) store chemical energy and they use cellular respiration to harvest energy.

The process of photosynthesis requires the storage of chemical energy by plants. During this process, the solar energy from the sunlight is converted to form glucose which can be further utilized during cellular respiration by plants to harvest chemical energy. Hence, the correct answer is option- a).

Option (b) obtain Carbon dioxide - is incorrect, because plants obtain carbon dioxide through the process of cellular respiration and not photosynthesis. During photosynthesis, carbon dioxide is required.

Option (c) is also incorrect because plants use photosynthesis to store chemical energy and cellular respiration to harvest chemical energy.

Due to the same reason, option (d) is also incorrect.
