Question

Which is correct for photosynthetic organs

• A. Light Energy $⟶$ Heat $⟶$ Chemical Energy
• B. Chemical Energy $⟶$ Light Energy $⟶$ Heat
• C. Heat $⟶$ Light Energy $⟶$ Chemical Energy
• D. Light Energy $⟶$ Chemical Energy $⟶$ Heat

Answer 1

The correct option is D Light Energy $⟶$ Chemical Energy $⟶$ Heat

Photosynthesis is a process by which green plants manufacture their food with the help of carbon dioxide and water in the presence of sunlight. When light energy is absorbed by photosynthetic pigment chlorophyll, then it gets excited and photosynthetic reaction center loses an electron. In this way, light energy is converted to chemical energy. Conversion of light energy into chemical energy is the primary event in photosynthesis. Then, this chemical energy is converted into heat. Thus, the correct answer is option D.
