TMV can cause plants to produce less chlorophyll. This causes leaf discoloration. Explain why plants with TMV have stunted growth.

Chlorophyll gives plants coloration so a discolored plant would have a lack of chlorophyll. This means that less photosynthesis would occur in the leaves of the plant, so less glucose is made as a result. Therefore there is less energy released for growth as glucose is needed for respiration. As glucose is also needed to make amino acids and proteins, there would be less amino acids and proteins for growth.
