Question

Choose the correct answer from the alternatives given.
Carbon dioxide movement into a plant leaf involves all of the following except

• A. Stomata
• B. diffusion
• C. electron transport system
• D. air

Answer 1

The correct option is C electron transport system

Carbon dioxide enters the leaf through stomata through diffusion from the air or atmosphere surrounding the plant and it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. It is not related to the electron transport chain that deals with the splitting of the water molecule and transferring the so-formed electrons to produce ATP and NADPH.

So, the correct option is, 'electron transport chain'.
