Two other major groups of flavonoids found in flowers
and leaves of all green plants. The function of these two flavonoids in plants
are____
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
Which of the following combination from the above statements is correct?
