This is a really an excellent question and something alot of world usually don"t think about. Theanswer is the all plant cells need oxygen tolive, due to the fact that without oxygen lock can"tperform aerobic respiration (respiration isthe procedure of breaking down food to gain energy).Of food you probably understand that as soon as plantsperform photosynthesis, they incorporate water,carbon dioxide, and the sun"s power to producesugar and also oxygen. For this reason the cell in the green partsof the plant, wherein photosynthesis is takingplace, gain all the oxygen they require from theoxygen created by photosynthesis. So cells inthe leaves and stems room okay. The trick is thecells under in the roots, wherein there is nophotosynthesis. In most plants, these cellsget your oxygen from waiting in the spaces betweendirt corpuscle in the floor (you"d it is in surprised howmuch empty room there is in the soil --mostly because earthworms arealways moving around, churning up the dirt). Butfor plants that live in soggy environments, that"snot one option, because water stop a lot of lessoxygen 보다 air go (we"re talk aboutO2 here, not the oxygen inH20).
So part wetlands plantshave arisen a tolerance for low-oxygenconditions, and a many them have actually reallyshallow source systems so they"re together close aspossible come the air. Mangroves room treesthat live in saltwater lagoons, and also they haveevolved one-of-a-kind roots, calledpneumatophores (Greek for "aircarrier"), the act choose snorkels because that the roots. However most tree don"t have these specialtolerances and also adaptations, which is why friend can"drown" your houseplants if girlfriend water them toomuch.
You are watching: Can a plant survive without oxygen?
We constantly hear around how plants use carbondioxide and also give off oxygen together waste, and howanimals(like us) use oxygen and also give turn off carbondioxide together waste, and how this is a really importantcycle in nature.
This is every true,but us don"t hearabout as frequently is that plants require oxygen tosurvive, too.
Plant cells carry out cellularrespiration just like animal cells do, and also thisprocess requires oxygen. Plants prefer rice cangrow in wetlands since they have actually air spacesbetween their cells, and they deserve to moveoxygen-rich air into those air spaces. The reasonwhy farmers thrive rice in flooded areas is becausethe rice will endure there, but many weeds willdie from lack of oxygen because they don"t haveair spaces in between their cells. If girlfriend seal aplant in an airtight terrarium, it will still growbecause it have the right to recycle both the oxygen and thecarbon dioxide that it uses. If you couldmagically remove all oxygen from the terrarium,though, the plant would certainly die.
Plants do need oxygen come survive. Theyrespire (take in oxygen, provide off carbon dioxide)the same means that animals do. The distinction isthat throughout the day, plants also performphotosynthesis, in i beg your pardon they take in carbondioxide and give off oxygen.

In any type of given24-hour period, a healthy, farming plant will giveoff a lot more oxygen 보다 it consumes, andconsume a lot more carbon dioxide 보다 it givesoff, so people usually don"t think about plantsneeding oxygen.
Wetland plants require oxygen too. There room alot that *bacteria* in wetlands that can livewithout oxygen, but every one of the tree (vascularplants, mosses, also algae) absolutely requireoxygen.
