  Light plays an important role in the life of all organisms. Name any three physiological processes in plants which are affected by light.

Answer:

                The apical buds present in tea and other plants prevents the growth of lateral buds in them, by releasing auxin hormone. This phenomenon is called apical dominance, Trimming of tea garden and botanical garden removes the apical bud and allowing the lateral buds to grow laterally and give plants a dense bushy appearance. The scientific explanation for this trimming method is that apical bud is removed thus results in the removal of auxin and phenomenon an of apioal dominance is overcomed.
