can plants survive in a 100% carbon dioxide enviroment?

Answer 1

I agree with tvballer6327!!!!!

Answer 2

OMG the answers here so far are absolutely moronic.

Photosynthesis - the process by which plants make food, requires no oxygen whatsoever. However one of the by-products of the process IS oxygen.

CO2 +H2O +chlorophyll + sunlight=glucose(plant's food) + the by-products...water and oxygen which are released through the stomata. Stomata are small openings on the underside of the leaves of plants where the photosynthetic process takes place.

Therefore it would be virtually impossible to sustain a 100% CO2 environment unless it was done in an artificial lab.

By the way "air" is for pumping up soccer balls. its called atmosphere, which is really 78% nitrogen and only 18% oxygen the other 4% is made up of like 20 other elements like argon,xenon,hydrogen,and carbon dioxide.

Answer 3

Certain plant can survive... On Earth here, there was no oxygen in the atmosphere until plant life put it there one billion years ago.

The problem with Mars is not it's atmospheric composition, but it's lack of a substantial atmosphere at all. It's gaseous density is less than 10% o Earth's... The majority of it is carbon dioxide, but the air there is so thin that everything freezes at relatively high temps. The 80ºF summer there is still not warm enough for plantlife... water is still ice at those pressures and temps.

Answer 4

No they cant.
Oxygen is released as a byproduct of photosynthesis.The plants need some oxygen to keep their cells alive. Once enough oxygen is present, the cells start functioning. After that the carbon dioxide can be converted into oxygen.

Answer 5

A plant in a 100% CO2 atmosphere would die from suffocation within an hour. Plants need oxygen just as animals do.

If the plant were exceptionaly large and vigorous and supplied iwth a very intnse light source it MIGHT be able to produce sufficient oxygen before it died to keep itself alive, but it is very doubtful.

Suffice it to say that if you placed yur houseplants on a CO2 atmosphere for more than a few minutes they would be dead.

Answer 6

Well, plants for a lack of a better word " breath" carbon dioxide & "exhale" give off - what we know as air. However I do not know what the % of carbon dioxide vrs other chemicals they take in would be. Interesting question.

Answer 7

No. Plants do still need to breathe oxygen as well, just not as much and they do create more than they need. That is one of the problems that we will face if we ever get around to colonizing Mars. There is plenty of CO2, but little if any oxygen.

Answer 8

It depends on what plants are we talking of.
Plants show high variability for the unicellular algae to large robust Angiosperms like the oak.
While it might be feasible for the lower groups of plants, for the higher groups it appears to be a impossibility

Answer 9

Theoreticaly yes, but the actual answer is no. Plants need the other bacteria and microbes and so forth in the soil to interact with. I should say they need the organisms that the roots are submerged in to stay alive and not soil. (I forgot about hydroponics which is the growing of plants with no soil).

Answer 10

Gases inhaled enter the alveoli interior the lungs. Oxygen diffuses into the capillaries by ability of the skinny walls of each and every alveolus (purely one cellular thick, and moist, to assist diffusion), even as carbon dioxide diffuses decrease back from the capillaries into the alveolus to be exhaled.

Answer 11

Never. They will surely die in that kind of an Environment as they require other gases as much as CO2 to survive & grow healthy.
