Subject: stomata and waxy leaves

I am a high school sophmore doing a lab comparing the number of stomata
on waxy leaves and less waxy leaves. (Wax as in the cutin produced by
the palisade mesophyll cells.) It turns out that the more waxy leaves
have less stomta per mm sqrd. than the less waxy leaves. I would be most
grateful is someone could help me with this. Please reply to 
[email-masked]

Thanks

This Vince again, I forgot to tell you what I need help on.(read
previous message) I cannot explain *why* does the waxy leaf have less
stomta than the less waxy
leaf. 
Thanks
thanks again

Dear Vince

What they told me in college was that the existence of a heavy wax coating
on leaves is generally an adaptation to dry conditions (or at least
conditions in which the plant needs to conserve water).  The decreased
number of stomata on such leaves is another such adaptation.  A plant with
these adaptations is generally refered to as being xerophytic (pronounced
"zero-fit-ick").  Hope this helps.

(8^)  Q-RAH!

A reduced number of stomata can also be do to a higher level of CO2 in the air.
