Which one includes growth promoters?
1 Auxin, cytokinin, \({\rm{ABA}}\)
2 Auxin, cytokinin, \(\mathrm{GA}_{3}\)
3 \(\mathrm{C}_{2} \mathrm{H}_{2}, \mathrm{ABA}\)
4 \(\mathrm{GA}, \mathrm{C}_{2} \mathrm{H}_{4}\)
Explanation:
Plant growth promoters are involved in growth promoting activities, such as cell division, cell enlargement, pattern formation, tropic growth, flowering, fruiting and seed formation, e.g., auxins, gibberellins and cytokinins.

Phytochrome is
1 Flavoprotein
2 Glycoprotein
3 Lipoprotein
4 Chromoprotein
Explanation:
Phytochrome is a soluble chromoprotein with molecular mass \(250 \mathrm{kDa}\). Plant grows towards sunlight because the red light from sun converts the chromoprotein into the active form (Pfr), which triggers plant growth; plants in shade show slow growth because the inactive form (Pr) is produced. If seeds sense light using the phytochrome system they will germinate.
