Eziphilayo plant uwase Water

uwase Amanzi okanye transpiration, - oku kuyinxalenye ebaluleke kakhulu yobomi esityalo. Amanzi lilo inkqubo iingcambu kunye neeminerali zichithakala nje ukuba ibalulekile ukuze ukukhula okuqhelekileyo eziphilayo. Uninzi lwamanzi wendele ngumphunga amagqabi.

Indima amanzi kuphuhliso yezityalo. Water - into ebaluleke kakhulu kwaye indima yayo kubomi isityalo kunzima zazi. Ngenxa amanzi ixhasa turgor weseli, ukwenza amagqabi kunye nezikhondo zithambile yaye liyaxhathisa. Ngaphandle isityalo ngokwaneleyo ulwelo ngokukhawuleza siyaphela.

Ukongeza, kunye amanzi lilo engcanjini izimbiwa zisiwe onke amalungu esityalo. Ukufuma ukwakhusela umzimba nobushushu. Komphunga kwamanzi izityalo lwenzeka ubukhulu becala ngenxa yokondliwa - ezikhethekileyo uluhlu amagqabi. Kwezinye umlinganiselo transpiration yenziwa bonke phezu isityalo ngokusebenzisa eli laphu nesigqubuthelo.

Izitomata kunye nokwakheka kwawo. Komphunga amagqabi kwamanzi kwenzeka ubukhulu becala ngenxa isakhiwo eyodwa ebizwa ngokuba stoma. Izitomata iqulathe iiseli ezimbini wabasiki Crescent imilo, phakathi apho kukho umsantsa encinane. Udonga engaphakathi iiseli yabalindi liyajiya kwaye engaphandle - obhityileyo. Phantsi yesakhiwo umngxuma encinane.

Izitomata zimi kumacala omabini sheet. Kodwa izityalo ezininzi ibekwe ingxenye engaphakathi kuyo. Kodwa izityalo amanzi, amagqabi luqhagamshelwano ngamanzi (umz, amanzi inyibiba), - kwicala olungaphandle igqabi.

Kubalulekile ukuphawula ukuba yokondliwa banoxanduva hayi kuphela komphunga ngamanzi, kodwa utshintsho zegesi kunye emoyeni - ngokusebenzisa kuzo ioksijini kunye carbon dioxide.

Ngumphunga yamanzi: kuthatha indawo? Njengoko sele kukhankanyiwe, transpiration nga kwenzeka lugubungela umzimba umzimba sisityalo - kule meko ibizwa ngokuba cuticular. Amagqabi, iziqu kunye namanye amaqumrhu izityalo abaselula legqunyiwe ngomaleko olunye sangaphandle - ngawo kwaye kukho nokususwa nokufuma. Xa izityalo abaqolileyo ngakumbi phezu olungaphandle ibhola lifakwa kwaye wax Ulobuza ekhusela nenyama yelahleko ngokugqithiseleyo ukufuma, nokuzisula ngaphandle. Ngoko ke, transpiration cuticular kumagqabi abaqolileyo kuyehla kube ubuncinane.

uwase Main udlula kuyo ngokusebenzisa yokondliwa. Ukuze uqalise lihamba kwamanzi izitya xylem le, ngoko ezinambuzelayo kweendonga kwiseli kwi kwizikhewu intercellular apho podustichnye abayiqokeleleyo ibinomthwebeba.

Ukuvulwa kunye nokuvalwa yokondliwa ikakhulu kuchatshazelwa umlinganiselo wamanzi. Xa ukufuma oluhlala iiseli wabasiki, bona kusolula uthabathe ngokohlobo iceba - kule meko isikhewu ivula. Ukuba amanzi ngokwaneleyo iiseli, bayakuyeka turgor, neendonga zawo kuwa phantsi kwaye uvale noqhoqhoqho.

Isimo isiphumo yokondliwa kunye nesiqulatho carbon dioxide. Ukuba inqanaba kwi nezihlunu izityalo liyancipha, iinkqubo ze-yokondliwa ivulekile iyasebenza. A e phezulu kakhulu iqela umsantsa igesi luvaliwe. Kungenxa yoko le nto yokondliwa zivaliwe ebusuku, xa iinkqubo photosynthesis zokumisa.

Komphunga amanzi kunye neempawu zayo zamanani. Njengayo nayiphi na inkqubo, transpiration iye izalathi yayo ubuninzi, ezisetyenziswa kwezolimo, inzululwazi kunye nezinye iinkalo zobomi bomntu.

Umzekelo, umlinganiselo transpiration ibonisa iigram ezininzi kangakanani amanzi ezabelwe inxalenye ethile kwingingqi zezityalo nganye kwexesha unit. Ngokulinganisa imveliso transpiration, kuyenzeka ukuba bathi indlela ubunzima olulophu isityalo elingathathwanga ngexesha komphunga obunzima buyikhilogram enye yamanzi. A ukuchaza ezi mpawu, unako ukufumana iimpawu ezithile ngamnye iintlobo zezityalo, ukuseka iimeko eziyimfuneko ukuze ikhule imveliso.
