Canadian pondweed does not have stomata. How then does carbon dioxide enter the leaves of the plant so that photosynthesis can take place?

Hi, basically since stomata is closed only other entrance is via the roots so i think CO2 dissolves in the water diffuses and then taken up by the pondweed, while O2 diffuses out of the pondweed.

That is exactly right jumela because the other life in the pond will release CO2 into the water where it will dissolve and deposit on the sea floor. Furthermore, if plants die or fish etc, they will have a certain amount of carbon in them and that will enter the soil allowing it to be absorbed in the roots of the pondweed. well done jumela and hope its the right answer !
