original_response: Also if you are interested in a science lesson..LOL..plants are green b/c of the chemical Chlorophyll
history: I really like the color green. Always was my favorite one. Nice, do you like the other additive primary colors, red and blue, as well? Yes, but green is my favorite, it is the color of forests and nature. Speaking of forest and nature, did you know that many shades of green were named after plants ? I didn't know that, I suppose it is because many plants are green
knowledge: Many plants are green mainly because of a complex chemical known as chlorophyll which is involved in photosynthesis.
