photosinthisis in the process in plants of taking co2 and water to
produce oxygen and glucose. there for it is important to global warming
because if we cut down the trees the co2 emisions will increase and
damage the o-zone layer.

there are many theors about global warming but one thing is for
certain. we need to cut down on the toxic emisions we produce especialy
co2, and we need to stop cutting down the trees which help us change
co2 into oxygen by photosinthisis

Any ideas? Any help would be appreciated. This is a variety of catnip
that only grows in Turkey. Thanks for your time.

i want information about a Gesnariaceae plant Didymocarpus pygmaea and
the other is Didymocarpus tomentosa

This is a simple question from a non-science student. For lanog, I have
wondered how plants get rid of wastes. As far as I know, plants get rid
of unwanted water by transpiration. What happens to all the unwanted
solids ?

I used it alot in the 1970s. It was a US govt printed book. It had a
green cover, hardback and thick. It was about 6" by 10". I remember a
page or two on pinyon pine showing its distribution range in the West.
It showed and talked about many trees in the US. Does anyone know the

yesterday I was walking on a dike and one moment I saw a wild carrot
plant. The funny thing was: the flowers were both white and pink (So
inside one flower there were differences). I'm very much interested in
what is happening here; if it is genetical, wouldn't all the flowers

Plant-eders,
The following was just posted to the Arabidopsis newsgroup by Tobias
Baskin.  It may be of interest to Plant-ed readers.  Apologies to those
who subscribe to both groups and got it twice.

Does anyone know anything about this plant, and where it can be obtained?

I understand that when sunlight is around trees and plants will give off
oxygen and soak up carbon dioxide (photosynthesis) - but at night is it true
that they will give off carbon dioxide?  If so, how much of each will be
released during the night and day.

I am looking for information about greenhouse experiments in space. I
have found lots of information on the NASA web, but mostly useless (at
least in relation with what I am looking for). I would like to know
what is today's "state of the art" in growing plants in

I been playing around with rhubarb for years, transplanting them here
and there. And I finally come to the conclusion that they do not like
direct sunlight in an open field. They like some shade under a tree. So
I formed this conjecture that if a plant has large leaves indicates

This plant is about 12 inches across and 10 inches tall, dark green
leaves with no flowers. Each leaf is longated and thick.(about 1/8
inch) At the base of each leaf, there is a short vertical leaf attached
the whole width of the parent leaf. Each leaf sprouts small plants all
