This is a really good question and something alot of human being usually don"t think about. Theanswer is the all plant cells require oxygen tolive, since without oxygen they can"tperform aerobic respiration (respiration isthe process of breaking under food to get energy).Of food you probably recognize that as soon as plantsperform photosynthesis, they combine water,carbon dioxide, and also the sun"s energy to producesugar and oxygen. Therefore the cells in the green partsof the plant, where photosynthesis is takingplace, get all the oxygen they need from theoxygen created by photosynthesis. So cells inthe leaves and also stems room okay. The trick is thecells under in the roots, whereby there is nophotosynthesis. In many plants, these cellsget their oxygen from waiting in the spaces betweendirt particles in the floor (you"d it is in surprised howmuch empty an are there is in the soil --mostly since earthworms arealways relocating around, churning up the dirt). Butfor plants the live in soggy environments, that"snot an option, since water stop a many lessoxygen than air go (we"re talk aboutO2 here, no the oxygen inH20).

So some wetlands plantshave arisen a yongin for low-oxygenconditions, and also a lot of them have actually reallyshallow source systems for this reason they"re together close aspossible come the air. Mangroves are treesthat live in saltwater lagoons, and also they haveevolved unique roots, calledpneumatophores (Greek for "aircarrier"), the act like snorkels for the roots. But most plants don"t have these specialtolerances and adaptations, which is why girlfriend can"drown" your houseplants if friend water lock toomuch.

Answer 2:

We always hear about how plants usage carbondioxide and also give off oxygen as waste, and also howanimals(like us) usage oxygen and also give off carbondioxide as waste, and how this is a an extremely importantcycle in nature.

This is every true,but we don"t hearabout as frequently is that plants require oxygen tosurvive, too.

Plant cells do cellularrespiration simply like animal cells do, and also thisprocess needs oxygen. Plants prefer rice cangrow in wetlands due to the fact that they have air spacesbetween your cells, and they have the right to moveoxygen-rich air right into those wait spaces. The reasonwhy farmers prosper rice in flooded areas is becausethe rice will survive there, but many weeds willdie from absence of oxygen because they don"t haveair spaces between their cells. If friend seal aplant in an airtight terrarium, it will certainly still growbecause it have the right to recycle both the oxygen and also thecarbon dioxide that it uses. If girlfriend couldmagically eliminate all oxygen native the terrarium,though, the plant would certainly die.

Answer 3:

Plants do need oxygen to survive. Theyrespire (take in oxygen, give off carbon dioxide)the same way that animals do. The distinction isthat during the day, plants additionally performphotosynthesis, in i beg your pardon they take in carbondioxide and also give off oxygen.

In any kind of given24-hour period, a healthy, cultivation plant will giveoff a lot an ext oxygen 보다 it consumes, andconsume a lot an ext carbon dioxide than it givesoff, so civilization usually don"t think about plantsneeding oxygen.

Wetland plants require oxygen too. There room alot that *bacteria* in wetlands that deserve to livewithout oxygen, but all of the tree (vascularplants, mosses, even algae) certainly requireoxygen.
