Chloropasts look green because they’re filled with a chemical called chlorophyll. This is what absorbs light to help with photosynthesis. However chlorophyll only absorbs red and blue light. It doesn’t use green light so this is reflected back, making chlorophyll, and therefore chloroplasts, green.
So, plants get there energy from sunlight. Sunlight is different wavelengths (which are different colors), this is what a rainbow is.
Plants contain Chlorophyll inside chloroplasts, which carries out photosynthesis to capture the energy from sunlight. The plant cannot use all the wavelengths / colours of sunlight, and it only uses red and blue. Because it ‘captures’ red and blue, but it does not need green, so this is reflected and is the colour we see.
