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.

They photosynthesise in order to get food. They combine light from the sun with chemicals from the air and make a kind of sugar from it which, along with chemicals from the soil, they feed on. This is one of the reasons why plants are so important – they are one of the only forms of life that doesn’t need other forms of life to feed on. Because of this, plants are the starting point for a lot of food chains and ecosystems. Also, photosynthesis takes in carbon dioxide so plants are important for stopping climate change.
Thank you so much for answering. I know how they photosymphasized but I didn’t now why, thanks so much for replying, it is so interesting that nature can do many things we cant even explain!
