Answer :
Answer:
The correct statement is
Option D. Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.
Explanation:
Photosynthesis is food producing process in which food is produced by plants in the presence of sunlight while respiration is energy releasing process in which energy is released due to the breakdown of glucose molecules.
Answer: D). Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of
these food molecules during cellular respiration.
Explanation: During photosynthesis, plants use light energy absorbed from the sun to manufacture organic food substances such as glucose in the presence of carbon dioxide and water to give oxygen as the byproducts but during cellular respiration, glucose produced in photosynthesis is broken down in the presence of oxygen (a byproduct of photosynthesis) to generate energy in form of ATP with the release of carbon dioxide and water as byproducts.
Equation for photosynthesis is 6CO2 + 6H2O + solar energy --> C6H12O6 + 6O2
Equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
