Question

The concept that light energy is converted to chemical energy in photosynthesis was given by

• A. Priestley
• B. Meyer
• C. Stephen Hales
• D. Helmont

Answer 1

The correct option is B Meyer

Stephen Hales observed that the volume of air just above the water surface decreased when a plant was grown in a closed atmosphere and concluded that air was being imbibed into the substance of the plant. He also noted that light enters leaf surfaces and flowers and may play a role in plant growth and development. So, this particular answer is incorrect.
Van Helmont concluded that plants get their food from water. So, this answer is incorrect.
Joseph Priestley discovered that plants produce oxygen. So, this answer is incorrect.
The concept that light energy is converted into chemical energy in photosynthesis was given by Meyer. He stated that the sun is the ultimate source of energy for both plants and animals and that when absorbed, plants convert this light energy into chemical energy through the process of photosynthesis. So, the correct answer is option B.
