Where would you expect to find stomata of a floating water lily be found?
On the upper surface of the leaf..





This is because the lower surface is constantly in contact with water while the upper surface is in constant contact with air , so its more difficult for gaseous exchange to occur at that surface as compared to the upper one
Reply:Water plants like the lily have stomata on the sides exposed to air ie. the part of the plant that's not submerged like the top of the leaves. If you think about it, it makes sense because it'll be easier for gas exchange.
Reply:on d upper surface of leaf, it is epistomatic
