Question:- Why plants look green?

Answer:- Mostly plants look green due to the presence of chlorophyll pigment. The colour of the object is the colour of the light reflected by it. When white light consisting of seven colours falls on plants, the chlorophyll present in plants absorbs all the colours except green. So, when a beam of white light falls on a plant, the green colour of the light is reflected. That is why, plants look green.
