MolecularMan14 Posted October 10, 2004 Share Posted October 10, 2004 This is a very strange question I know, but I really dont know the answer myself- Are there any stomata on the upper epidermis of a leaf? If so, in all plants or just some? I would assume the answer is no, but my honors bio teacher likes to pull tricks Link to comment Share on other sites More sharing options...
Guest Bob Kallen Posted October 13, 2004 Share Posted October 13, 2004 There are approximetly 17 on each plant, however recent studies indicate that some plants such as the Venus Fly Trap contain only 16. Link to comment Share on other sites More sharing options...

VendingMenace Posted October 13, 2004 Share Posted October 13, 2004 There are approximetly 17 on each plant, however recent studies indicate that some plants such as the Venus Fly Trap contain only 16. HUH? Do you have any sort of reference for that. i would find it interesting myself to read up on it. Thanks As to the original question, I am unaware of any plants that have stomata on top of the leaf, but who knows -- life have a way of supprising us. though i think for your class, a safe answer would be that they only occur on the underside -- someone correct me if i am wrong edit: The reason for them being on the underside is that the stomata are somewhat light activated and if they were on the top side, the plant would loose to much water Link to comment Share on other sites More sharing options...
Sayonara Posted October 13, 2004 Share Posted October 13, 2004 Kallen is deliberately talking crap. Or he was, until he was suspended. Link to comment Share on other sites More sharing options...

Primarygun Posted October 14, 2004 Share Posted October 14, 2004 Sorry I don't know , I only know water plant doesn't have stomata and no upper epidermis. Hope it would help. Link to comment Share on other sites More sharing options...
tman Posted September 22, 2005 Share Posted September 22, 2005 Plants are capable of having stomata located on the top of the leaf. Some plants that live in water, known as hydrophytes, have stomata on the top of the leaf. Since the leaves float on water it would be impossible for gas exchange to occur if the stomata were located on the bottom of the leaf. Link to comment Share on other sites More sharing options...
ecoli Posted September 22, 2005 Share Posted September 22, 2005 Land plants don't, AFAIK, especially in hotter climates and never in deserts. Sun's too hot, water loss would be far too great. Link to comment Share on other sites More sharing options...
