ant regulation mplete the following statements. Choices may be used once or not at all. In plants, molecules called respond to light. These molecules consist of a protein bound to a ectin control how plants molecule photoreceptors flowers Photoreceptors absorb certain wavelengths of and change shape, which can influence the genes as well as the action of hormones. of higmotropism light Plant growth either toward or away from light is called phytochrome phototropism When photoreceptors absorb light, the ne migrates to the shaded side of the stem and causes elongation of cells on that side glycolipids A photoreceptor calledis needed for seed germination and for certain physiological cycles, such as the opening and closing of the production of reproductiáve structures called for gas exchange and transcription The time of flowering in some plant species is regulated by which is the length of the day. Long-day and short- mycorrhizao day plants flower based actually on the hours of uninterrupted which is when phytochrome is inactive. ??? 7 8 0 del

Explanation / Answer

1. PHOTORECEPTORS control how plants respond to light. They contain PHYTOCHROME molecule.

2. Photoreceptors absorb certain wavelengths of LIGHT and change shape. This can alter the TRANSCRIPTION of multiple genes.

3. PHOTOTROPISM refers to movement of plants in response to light. AUXIN accumulates on the other side of the light.

4. PHYTOCHROMES are needed for seed germination, opening/closing of STOMATA and FLOWER production.

5. The time of flowering is dependent on LIGHT duration or uninterupted DARK duration.
