Hint	Answer
Pigment. Attracts pollinators/seed distributors. Absorbs green and yellow light, reflects red, violet, yellow, and orange light.	Betalains
Seed germination	Phytochromes
Shade Adjustments	Phytochromes
Photosynthesis (2)	Chlorophyll, Carotenoids
UV light damage (3)	UVR8, Anthocyanins, Betalains
Pigment. Attracts pollinators, protects from UV damage. Absorbs blue and green light, reflects anything from red to purple depending on pH.	Anthocyanins
Circadian Clock	Cryptochromes
Phototropism	Phototropins
Pollination/seed dispersal	Betalains

Hint	Answer
Photoreceptor. Optimize growth and other photosynthetic operation, phototropism, leaf opening, chloroplast movement, light induced stomatal opening. Absorbs blue light	Phototropins
Photoreceptor. Helps with plant growth/development, as well as circadian clock. Absorbs Ultraviolet and blue light.	Chryptochromes
Photoreceptor. Regulates light induced development responses, such as seed germination and flowering time. Absorbs red and far red light.	Phytochromes
Flowering	Phytochromes
Stomatal opening	Phototropins
Senescense	Phytochromes
Photoreceptor. DNA repair, production of sun protection pigments, reduced hypocotyl length. Absorbs UVB light.	UVR8
Pigment. Hormone and photoprotective functions (light trapping for photosynthesis), protects DNA proteins and lipids. Absorbs blue and green light, reflects yellow, red, and orange light.	Carotenoids
Pigment. Absorbs red and blue light, reflects green and yellow light, used in photosynthesis	Chlorophyll
