BIOXI15: PLANT GROWTH AND DEVELOPMENT

338186 Phytochrome is

1 Flavoprotein

2 Glycoprotein

3 Lipoprotein

4 Chromoprotein

Explanation:

Phytochrome is a soluble chromoprotein with molecular mass $250 kDa$ . 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.
