Answer:
ATP.
Step-by-step explanation:
- Adenosine triphosphate - ATP, is a molecule that carries energy in stored form.
- ATP is the energy currency of the cell, and it is formed in plant cells from a process called photophosphorylation in which a phosphate group is added to a molecule(ADP-Adenosine diphosphate) using energy from light. All living organisms weather it is plants, animals, microbes etc. uses ATP.
- In Photosynthesis; plants, few species of bacteria and some protistans use sunlight as energy source and produces glucose from carbon dioxide and water.
- This glucose formed in photosynthesis can be converted into pyruvate and further to carbon dioxide which releases ATP by cellular respiration.
Result: Plant synthesize ATP which is main source of energy.
