Photosynthesis is the process that plants use sunlight to synthesize their food. Plants use carbon dioxide and water and generate oxygen as the byproduct.
Of course it does. It is a green photosynthetic organism just like other vascular plants. It uses blue and red light (not green light) to make glucose (sugar) from CO2 and water. The source of the water for a water lily is simple enough to understand however where it gets its CO2 is more problematic. Water lilies do have stomates in the upper surfaces of their leaves so they can take up CO2 directly from the atmosphere. They also have an internal gas plumbing system called aerenchyma and so they can absorb CO2 dissolved in the water (just like algae) and they can also use CO2 from the mud in the bottom of the pond. If you cut a petiole of a water lily leaf underwater gas with a lot of CO2 in it will bubble out for hours. Analysis shows that it usually has a lot more CO2 in it than is found in air. *I am currently publishing a paper in the International Journal of Plant Sciences on Photosynthesis in water lilies.

I don't think they even have chlorophylls. Chlorophylls r founded in chloroplasts, but animal cells don't even have chloroplasts. Chlorophylls r used by producters during photothesis, but animals r consumers, not producters. They don't have to do photothynthesis.
