Aquatic plants are also usually green like topside plants, to absorb the most of the sunlight spectrum that enters the atmosphere for photosynthesis process to occur.many aquatic plants grow leaves with a thin cuticle that protects them from the elements, but also has enough pores to allow carbon to enter very easily, more easily than most kinds of plants. Aquatic plants do not usually have stomata to absorb air, because there is no air to absorb.so They absorb oxygen by leaves which have air pockets.The oxygen they produce and release into the water is almost always sufficient for their needs, and is absorbed back into the plant as it is needed.
