Why aren't black lights black?
Black as a color would absorb all visible frequencies of light. A "black light" is not actually black, but rather emits most of its light in the ultraviolet frequencies. This light is invisible to our eyes except that it interacts with certain materials that fluoresce (glow in the dark) when they absorb UV light. These lights are also used for indoor plants that need UV light to grow.
What do green plants algae and some bacteria need?
Green plants, most algae and some bacteria need access to sunlight, or a source of broad -spectrum visible and UV light. This is because these organisms derive energy from the light.
How uv rays affect vegetables?
UV rays affect vegetables. They alter their chemical composition.
Why do plants need direct sunlight?
I believe (do not quote me; I'm not sure) that plants do not need direct sunlight. Plants perform photosynthesis, which requires light from the sun to make energy- and I believe that plants need a wider light spectrum than just visible light. Therefore, plants need sunlight or the closest synthetic approximation (for example, fish tank lights often emit UV rays and possibly others in addition to normal light, letting aquatic plants live).
How does halobacteria protect itself from destruction by UV light?
halobacteria produces salt and chloride layer on top which shortens the UV wavelength protecting itself from UV light. that's why they grow fantastically on Mars.
If you block UV rays will your plants grow?

How do Plant light bulbs work?
The fluorescent type of light bulbs (correctly called lamps) have a phosphor that besides emitting visible light (400 to 750 nm) also emits some UV enengy in the UV-A range. Plants need visible light and some UV-A to be effective.
How do the Yaqui tribe grow their food?
with UV light bulbs

Can UV light radiation effect growth?
Yes. Plant life is known to benefit from UV light. An example is people who grow their own marijuana indoors under UV lights.
