Answer:
Plants use cellular respiration to harvest the energy stored in the molecules
Explanation:
Plants, just like any other living organisms, need energy to power their cellular processes. Therefore plants also perform cellular respiration by burning energy molecules like glucose. The difference with plants, unlike animals, is that they make their own glucose from abiotic factors like sunlight and carbon dioxide. They do this through the process of photosynthesis. Animals have to consume ready-made glucose that emanated (directly or indirectly)from plants.
