and when does it give ot the gas

what gas does it give out

Plants always oxygen, and take in carbon dioxide. Oxygen keeps humans alive, and carbon dioxide keeps plants alive.

Plants perform two distinct processes: photosynthesis and respiration. Photosynthesis is the process by which they (a) create glucose (a type of sugar) from carbon dioxide in a phase called the Calvin Cycle, and (b) create high energy NADPH and oxygen during the light-dependent reactions. Plants will give out oxygen ONLY during the day, since, it's production is dependent on light to stimulate photosystem II to split water into molecular oxygen and protons.
Independent of photosynthesis, plants (just like animals) constantly undergo respiration to produce ATP, which they use for many metabolic process. ATP uses oxygen and releases carbon dioxide.
Therefore, at night, plants will release carbon dioxide only. Hope this helps clear a up a widespread misconception.

For all of you who know of someone who was in intensive care, those who received a lot of flowers, you know that they remove the flowers at night. Why?
#1. People are weaker during the night than during the day;
#2. People who are weaker from sickness, injury, surgery, dan die more easily during the night;
#3. Plants ONLY GIVE OFF OXYGEN when they are producing oxygen through PHOTOSYNTHESIS (Biology 101, FOLKS!!!!) When these plants are not using photosynthesis, they give off carbon dioxide, just the same way animals (including humans!) do, and they take on (breathe in) oxygen.
But, for all you skeptics that did not take Bio 101 or don't recall this most basic of all Bio 101 events, check out:

You will see from this third site that a lot of people are confused about this oxygen/carbon dioxide issue.
I reckon that is proof positive that public schools are NOT doing their job, or
The Darwinists are wrong: people are NOT getting smarter. Pick your choice.

During the day plants take in carbon dioxide and combine it with water to make sugar. Oxygen gas is a byproduct of this reaction, which is called photosynthesis.
During the night, plants combine the sugar with oxygen to obtain chemical energy. Carbon dioxide is the byproduct in this reaction which is called respiration.
Plant respiration is exactly the same chemical process as animal respiration, but in plants, the reaction goes much more slowly.
Some species of bacteria-like organisms are able to use heat energy to make sugar from hydrogen sulfide and carbon dioxide. This reaction might be called "Thermosynthesis". Pure sulfur crystals are the byproduct in this reaction.

The truth is that after photosynthesis is done and the sun is no longer causing the process plants switch to taking in oxygen (while consuming the energy from photosynthesis) and release CO2 but the deal is that they produce more oxygen during the day then they use at night! This is right, don't listen to the others who obviously haven't read very many science text books!
The guy below me has a awesome answer and he is right aswell!

Indoor vegetation easily "devour" carbon dioxide and emit oxygen. subsequently you're apt to breath extra perfect (no longer worse) once you sleep with vegetation. you may ought to have a super type of vegetation, whether, earlier the oxygen point on your room may well be effected to the factor you may observe it. the quantity of water to offer a plant relies upon thoroughly on the type of plant. Many merely choose slightly water as quickly as each week. As a wide-unfold rule you merely ought to water them whilst the soil is dry to touch. Cactus needless to say choose little or no water yet sandy soil. in case you permit a plant get incredibly dry and you water it a lot, the water will run perfect by, onto your table. a extra perfect decision if so is to water in user-friendly terms slightly, then come again quarter-hour later and water extra. The dampened soil will easily take in a lot extra water the 2d time.

Plants are no more capable of giving out carbon dioxide than animals are of giving out oxygen. What kind of craziness have you been reading?

Plants give out oxygen during the day and nitrogen at night.
(LOL -- get it? "night"-tro-gen?)
Never mind, I was feeling silly.
Seriously, plants take in carbon dioxide and give out oxygen. Animals on the other hand do the opposite. Animals breathe in oxygen and breathe out carbon dioxide.
Hope this helps!

it takes in carbon dioxide all the time and then in return gives off oxygen continually
