I understood plants exchange needed molecules through stomata in the leaves. Then how do plants which are submerged do this?

plants in water have specialised parenchymatic tissue called aerenchyma throughout the plant body which helps them to breathe

by oxygen dissolve in water
A submergent plant or submergent vegetation is a plant that is completely beneath the surface of water. Most submergent plants are firmly rooted in the soil. Examples include elodea (Elodea canadensis) and eelgrass (Vallisneria americana)
An emergent plant is one which grows in water but which pierces the surface so that it is partially in air. Collectively, such plants are emergent vegetation.
This habit may have developed because the leaves can photosynthesize more efficiently above the shade of cloudy water and competition from submerged plants but often, the main aerial feature is the flower and the related reproductive process. The emergent habit permits pollination by wind or by flying insects.

They have gills.
No, i'm just kidding. I'm pretty sure that they feed off the oxygen that IS in the water, as there is of course some in there. Water plants are made to live underwater. Normal plants need water, underwater plants just happen to need a lot more :D

Windom Earle, Your assertion that your son not having gills disproves evolution is laughably ridiculous. Evolution does not claim that such a drastic change in DNA that would affect the entire biochemical operation of an organism can take place within one generation. This sort of change takes tens of millions of years. You cannot pick one type of mutation out of the billions of possibilities, and state that because you have not seen it occur in one particular individual, evolution must be false. I wish you the best, and I'm happy to hear that your family does not have cancer. But it would be in your best interests to log off your computer, learn critical thinking skills, then log back on before posting more questions. PS. It occurs to me that this post may have been a joke... If so, I commend you on your sense of humor, and PLEASE don't take offense to what I wrote above. However, if you are a creationist and you ACTUALLY BELIEVE that you have a point, I stand by what I said.

Plants can produce oxygen by photosynthesis. It means that they only need water, carbon dioxide and minerals. Since sunlight can get through water (up to certain depth), carbon dioxide is soluble in water, even underwater plans can do photosynthesis.

Light can penetrate into water some distance and the underwater plants capture energy from this light using chlorophylls. Check more details here...

Under water plants breathe with the help of roots arisen from water outwardly towards atmosphere.
