If there were no Sun, and no other source of radiant energy, the plants (and the entire planet) would quickly freeze. And since the color of an object is determined by the color of the light that is reflected by the object, with no light there would be no color, and everything would be black.
If we grow plants under artificial light on a space station, then the light on the space station (even if artificial) would be the same kinds of light that we humans prefer, so the plants on the space station would continue to be green.
Green plants.
The energy for photoshythesis in plants come from the sun.
From the sun. Its called photosynthesis. They get nutrients from the sun's heat.
Chlorophyl
They take the sun's energy and with chloroplasts (which make plants green) turn the sun's energy into sugar.
Green plants need the sun because plants take energy from the sun which gives plants food and helps them grow.
