Question

What happens when the roots are 'exposed' to sunlight?​

Answer 1

Answer:

Despite growing underground, largely in darkness, roots emerge to be very sensitive to light. ... We demonstrated that the sensitivity of roots to salinity is altered in the light-grown Arabidopsis roots. Particularly, light-exposed roots are less effective in their salt-avoidance behavior known as root halotropism.
