Do plants have melanin or specific pigments that protect them from UV damage?
Does chlorophyll absorb UV in/out the process of photosynthesis? Is the bark
dark because it contains melanin? Can trees/smaller plants get genetic mutation
that causes uncontrolled cell growth from UV? Is there a way that I can test
whether plants, bark, or any organic structure have melanin easily?
