Ranks the following in increasing atomic radius

S, Mg, Al

S: 16-10 +6

Mg: 12-10 = +2

Al: 13-10 +3

So: S < AlMg

In the light, cry1 is activated directly by blue light and indirectly by blue lightinduced phosphorylation. Activated cry1 forms a complex with COP1 and SPA1 via the C-terminal domain, preventing them from degrading protein targets such as HY5

Blue light depolarizes membrane of hypocotyl cells and inhibits of growth rate.

This membrane depolarization is caused by the activation of anion channels, which facilitates the efflux of anions such as chloride.

an anion channel blocker, NPPB (5-nitro-2-[4-phenylbutylamino]- benzoate), prevents the blue light–dependent membrane depolarization and decreases the inhibitory effect of blue light on hypocotyl elongation.

In Mougeotia, the photoreceptors regulating chloroplast movement consist of a fusion between phytochrome and a phototropin known as neochrome, and show typical bilin binding as well as red/far-red reversibility.
