The form of pigment which inhibits germination is
1 $\mathrm{P}_{760}$
2 $\mathrm{P}_{730}$
3 $\mathrm{P}_{650}$
4 All of these
Explanation:
B The pigment phytochrome behaves the following way: red wavelengths $(650 \mathrm{~nm})$ and far- red wavelengths $(730 \mathrm{~nm})$ stimulate and prevent seed germination, respectively. Germination $\leftarrow \mathrm{P}_{730} \stackrel{\text { far red } \lambda(730 \mathrm{~nm})}{\rightleftharpoons} \rightarrow$ Nogermination

Chlorophyll molecules are green in colour because they. :
1 transmit green light
2 transform green light
3 reflect green light
4 absorb green light
Explanation:
C Chlorophyll molecules are green in colour because they do not absorb green light but only reflected. Chlorophyll absorb blue and red light wavelength from visible spectrum. Chlorophyll change light energy into chemical energy. Maximum photosynthesis in white light. Minimum photosynthesis in green light.

Phytochrome becomes active in:
1 green light
2 blue light
3 red light
4 none of these
Explanation:
C Phytochromes is activated by red light, \& Pfr is activated by far-red light, so phytochromes become active in red light.
