Answer 1

Plants prefer red light because chlorophyll absorbs and recovers usable energy best at that frequency.

Photosynthesis in plants requires two photons of light, one to split the water, and a second a moment later to boost the energy level of the electrons in the PS1 (P700) step. Red light is very good for this second step, other colors are actually harmful.
