a) protect plants against being eaten by herbivores and against being infected by microbial pathogens

b) Protect cells from excessive UV-B radiation (280–320 nm) because they accumulate in the epidermal layers of leaves and stems and absorb light strongly in the UV-B region       

c) flavones and flavonols secreted into the soil by legume roots mediate the interaction of legumes and nitrogen-fixing symbionts

d) They are are coloured terpenoid compounds that also serve as accessory pigments in photosynthesis
