Carbon dioxide used in the Calvin cycle comes from the atmosphere. It diffuses into the leaves of the plant through the stomata and enters the intercellular air spaces. From their it diffuses through the cell walls of the mesophyll cells, through the cell membrane and through the cytoplasm, where it enters the chloroplasts. The Calvin cycle takes place in the stroma (matrix) of the chloroplasts. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/G/GasExchange.html See: http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookPS.html

∙ 12y agoThe first Organism's use of CO2 originated 3,000,000,000 - three billion years ago, give or take 500,000,000 - five hundred million years.

What is bad about CO2?
co2 is not bad at all because that is what plants live off of. and without co2 and plants could not live and provide oxygen for the animal kingdom
What takes co2 out of the air?
plants
What does co2 have to do with science?
co2 is the gas that we exhale. Scientist's think this gas causes global warming. ( plants filter co2 )
What power stations produce CO2?
Coal fired power plants,Petroleum power plants,
Best way to Lock up CO2?
As trees / plants.
Where does the oxygen that plants release into the atmosphere come from?
It is the Oxygen from the CO2 and H2O tat they use to make sugars.
Why do plants use co2?
for food
What do mammals produce that plants use?
co2
What is a use that CO2 has on nature?
Plants need it for photosynthesis
Do plants ever give off Co2 if so when and where does it come from?
YEah
What plants use during photosynthesis?
Plants use air, sunlight, carbon dioxide(CO2), and water.
Do plants absorb carbon dioxide?
Plants use CO2 in photosynthesis. They convert CO2 and H2O into carbohydrates through a series of metabolic pathways.
What is the effect of green plants on the earth's climate?
Plants use CO2 and release O2
What gases do plants use in plants photosynthesis?
There is only one gas. It is the CO2 gas.
What plants use the carbon dioxide produced through respiration?
ALL of them! CO2 is CO2, the source is irrelevant.
Can plants use as much co2 in photosynthesis as provided?
for each cycle they use 6 co2 molecules, but over time, they could use it all
How is co2 in the air useful to plants?
The plants use CO2 from air for photosynthesis. The air entering into its leaves through stomata comes in contact with photosynthetic cells and diffuse CO2 for assimilation to form carbohydrates.
