If a plant has enough light and water but very little green pigment in leaves, why will food formation decrease most?
Answer and explanation
Correct answer: Light energy will not be absorbed effectively
Photosynthesis requires light energy, carbon dioxide, water, and suitable pigments. Chlorophyll, the main green pigment, absorbs much of the light energy used to drive the reactions that form glucose. If chlorophyll is greatly reduced, light capture becomes inefficient even when water and light are available, so option B is correct. Carbon dioxide entry does not stop immediately, roots can still absorb minerals, and phloem transports food rather than water.
