If it has light, the flashlight is working.
A "white surface" is one that reflects all colors of light. That's why it looks white when a white light shines on it, and that's why you call it "white". If only red light shines on it, then it looks red.
The plant would never flower, it needs blue light to flower but it would grow normally....
All other colours except red are absorbed.. The reason it seems red to our eyes is because only red colour is reflected back.
Well, why do you call it a red shirt ? Could it be because it absorbs all colors of light except red, so that when white light shines on it, all colors except red soak into the shirt, and red is the only light left to travel from the shirt to your eye ? If that is so, then what happens if no red light shines on the shirt ? Is there any light left to travel to your eye ? No ? Well then, what color do you see if no light travels from the shirt to your eye ? I hope Socrates would be proud.
Correct. No light, no color.

It would be yellow. Yellow surfaces only reflect yellow, light makes everything that is white or its own color the color of the light, and bananas are yellow.
