QER question so marks for spelling etc too but if anyone has bullet points of things to include that would be great! :)

Answer 1

Answer:

Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.

In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.

In photoperiodism flowering and other developmental processes are regulated in response to the photoperiod, or day length.
