What occurs when light causes electrons to move when it hits some substances?
The electrons absorb the light energy, which excites them.
What is it called when substances give off light or another form of electromagntic radiation when they absorb energy?
fluorescence
What substances absorb energy from an outside source and then emit some of it as visable light even after the source is removed?
phosphorescent materials do this
What are the substances in plastids that absorb various wavelengths of light?
Pigments in plastids absorb various wavelengths of light.
Why do dark and light colors absorb different amounts of heat energy?
The difference is in the substances of which they're made, and how muchincident radiation those substances absorb or reflect.And that should really be your question. You should be asking why differentsubstances absorb different amounts of the energy that shines on them.The question you did ask isn't really a question, once you understand what's going on.Some colors are dark, because they absorb more light, and incidentally more heat too.And some colors are light, because they absorb less light, and by the way less heat too.

Why are there no substances that convert visible light into UV?
UV has higher energy (per photon) than visible light.
Does trees absorb sun light?
Trees don't absorb sunlight as such but more USE sunlight to convert into energy through a process called photosynthatsis.
What substances absorb energy from an outside source and then emit some of it as visable light even after the source is removed?
phosphorescent materials do this
Which substances is green pigment in chloroplasts that absorbs energy for photo systems?
They are the chlorophyll pigments. They absorb frequencies from visible light
What are the special qualities of chlorophyll a?
Chlorophyll a can absorb solar energy, but only a few in the excited state of chlorophyll a can convert light energy into electricity.
What are the substances in plastids that absorb various wavelengths of light?
Pigments in plastids absorb various wavelengths of light.
