Which pigment responsible for photomorphogenetic response?
1 Phytochrome
2 Chlorophyll-a
3 Chlorophyll-b
4 Xanthophyll
Explanation:
A Phytochrome is the pigment responsible for photoperiodism. Phytochrome controls seed germination, initiation of flower and the start of blooming by detecting the presence or absence of light. It is a chromoprotein with a chromophore, a part that detects light, and it has two states: P600 (Pr) and P730 (Pfr).

Which one of the following does not play any role in photosynthesis?
1 Phycocyanin
2 Xanthophylls
3 Phycoerythrin
4 Anthocyanin
Explanation:
D Anthocyanins are colored, water-soluble pigments. Anthocyanins responsible for the colors, red, purple and blue in fruits and vegetables. Phycocyanin, phycoerythrin and Xanthophylls are photosynthetic pigment. There are reserve in different group of plants.

The trapping centre of light energy in photosystem-I is:
1 $\mathrm{P}-660$
2 $\mathrm{P}-700$
3 $\mathrm{P}-680$
4 $\mathrm{P}-630$
Explanation:
B The trapping centre of light energy in photosystem-I is P-700. It receives electrons from photosystem-II by plastocynine. Thus, in the two photosystems, plastocyanin works as a plug between both photoactors.

A small protein attached to the outer surface of the inner membrane and which acts as a mobile carrier for transfer of electrons between complex III and IV is
1 cytochrome d
2 cytochrome c
3 cytochrome b
4 cytochrome a
Explanation:
B Cytochromes are iron-containing pigment found in all green cells in which aerobic respiration is taking place. Cytochrome is a small protein found attached to the outer surface of inner mitochondrial membrane. In the ETS chain, cyt-c transfer one electron from the third complex, cytochrome B, to the complex IV cyt-c.
