Following are certain statements are related to the effect of red and far-red light;
a) under a dense canopy much of the red light is absorbed by plant pigments, resulting in transmittance of mostly far-red light
b) Pr (red) has highest photon flux at 680 nm while Pfr (far-red) has highest photon flux at 730nm
c) Pfr far-red light–absorbing form, which is considered to be the physiologically active form of phytochrome
d) R:FR ratio is strongly affected by the presence of a canopy because chlorophyll absorbs far-red but not red light

There are some given statements about co-translational translocation in endoplasmic reticulum

a)SRP and the nascent polypeptide chain–ribosome complex bind to the integral membrane translocon

b)SRP and the nascent polypeptide chain–ribosome complex is strengthened by the binding of GTP to both the SRP and its receptor.

c)ER signal sequence emerges from the ribosome, it is bound by a signal recognition particle (SRP)

d)Hydrolysis of the bound GTP accompanies disassembly of the SRP and SRP receptor
