Chlamydomonas nivalis: iimpawu zezakhiwo, indawo

Imizobo Amazing kunye unique ngamanye amaxesha kubonakala emhlabeni. Ngokomzekelo, maxa wambi kukho emibalabala, kwizimanga kubuhle, eyaziwa ngokuba "ivatala njengekhephu". Nokukubangela chlamydomonas snow, umzimba encinane, nto leyo imfihlelo kwabaninzi.

Kwaye oko aya kukuthetha izazinzulu?

Xa sibhenela biology, ungabona ukuba chlamydomonas ikhephu kwinzululwazi ekuthiwa Chlamydomonas nivalis. Le mveliso, nto leyo iba lona lisiza. Nangona ukupeyinta kwekhephu in pink obomvu, loo nto ithathwa njengento oluhlaza.

Esi silwanyana ifumaneka kuphela amanzi acocekileyo, kokwabo izityalo single-elilodwa. Isibakala sokuba nobulembu eluhlaza kuza phezu babeziindleko nekhephu kwi ebomvu, ngenxa yobukho kubume zalo kombala, ebizwa ngokuba "astaxanthin". Ngaphandle kwalo, isityalo liquka ngombala oluhlaza, yaye - nkqu nabafundi eyaziwa ngokuba yiklorofili.

Xa kwakha ngekhephu chlamydomonas, uthethe ngale "njengekhephu liqhuma". Imiphezulu abe umthunzi olumnandi epinki, kwaye ngamanye amaxesha baba ebomvu wesihogo, ngokungathi indalo recreates imifanekiso evela imovie eyoyikekayo.

Chlamydomonas nivalis fanele ukuba abathandi ezibandayo. Le nobulembu - ephambene ngqo kwiklasi emininzi thermophilic izityalo kwiseli enye.

ngezigaba

Kelp eziphilayo namhlanje kusiwa sodidi Chlamydomonas, ukubayinxalenye kusapho igama elifanayo. Ngoko, ke, kuba yinxalenye yale nkqubo, obizwa ngokuba "volvoxes". Iklasi ezi zityalo got igama layo ngenxa kombala equlethwe eziphilayo, ibizwa ngokuba "chlorophyceae". Umgangatho esiphakame sisahlula - zesebe. Isityalo bobabo lona lisiza eluhlaza. Okokugqibela, kuba ubukumkani izityalo.

iintaba ezintle

Ekubeni chlamydomonas iqhwa lobushushu kufuphi zero uziva mountaineers ezinkulu nabahloli intlomo yasentla banethuba ubone umfanekiso omhle.

Phela, opinki - kuphela ngomthunzi ikhephu phezulu ezintabeni. nakujoliso olutsha nazo zifumaneka:

• purple;
• elibomvu;
• brown;
• elityheli.

Isizathu sokuba nokugqama ikhephu - ohlala kuyo izityalo ezincinane.

Uyafa chlamydomonas iqhwa degrees-4, ngoko ukubona indalo ngabo bantu kuphela ningoyiki yokubanda.

Amaxesha amaninzi umzobo omangalisayo pink umbala singabonakala:

• e Antarctic;
• eCaucasus.

Xa ususa umaleko phezulu, kuvela ukuba ngaphakathi yayimhlophe. Oku kwenzeka ngenxa ingakumbi ubomi esi sityalo singaqhelekanga - ". Chlamydomonas ikhephu" ulwelwe yokuhlala - kuphela umaleko komhlaba.

Yenzeka njani le nto?

Ukuqhubeka kudala pink ayikho nje njalo, kwaye phantsi kwempembelelo iimeko zangaphandle. Eqhubela phambili iqala xa umoya ufudumele. Kule imeko abaqhelekileyo kwi-inshorensi ikhephu izityalo na aleleyo, kodwa xa ilanga liqala banobubele, umaleko ongaphezulu iye zinyibilikisiwe, kunye neemeko kangangoko yokuvelisa kwakhona. Kodwa kuthatha ixesha elidana noko, ngenxa yokuba chlamydomonas ikhephu kubushushu degrees 4 ngokukaCelsius sele abulawe.

Ukuba ngexesha elifanelekileyo endaweni ekunene, lo mhambi bagcine lona lisiza esebenzayo kunye ndixakekile ezincinane. Kombala oluhlala ngokukhawuleza. Ukufunda le simo, abaphandi wathabatha iisampuli ikhephu, uze emva koko kuvavanywa ngemicroscope ngokutshisa ukuya lobushushu yokunyibilikisa kulo. Kuyaphawuleka ukuba amanzi ngesantya esiphezulu inokuqala ihambele amasuntswana bubomvu. Ngamnye kubo - oku sisityalo eyahlukileyo.

non-eyayicace ezicacileyo

Namhlanje, ebona, umhambi, ilungu uhambo, ukuba phakathi babeziindleko ngekhephu, ngokungathi igazi elimsulwa, kuba esoyika okanye Ndamangaliswa ngulo mba, kodwa uyakuvuyela wavula phambi kwakhe ubuhle esinqabileyo. Kodwa akubi njalo, yonke into nje.

Kude kube kamva nje, abantu ikhephu ebomvu imfihlakalo ngokwenene. legends Zingaphi ezinxulumene nayo! Kuphela umzuzwana eyadlulayo, izazinzulu ndicinge ukuba yintoni na imvelaphi isenzeko. Ulwelwe wafunyanwa kwi Arctic Antarctic. Kwakhona bafumanisa ukuba va microorganisms okulungileyo lweemeko iphakeme eziphakamileyo, okwenza thanga yaphuhliswa ezintabeni.

Namhlanje, zebhayoloji wayesele iintlobo 140 of ulwelwe kunye nezinye izinto, ekwaziyo udlulisele iqhwa kwamnandi, original, umbala nemvelo.

Nature kwakhona ukumangala

Xa inzululwazi wasibamba lona lisiza kakhulu, abaphandi bamangaliswa, ngenxa yokuba chlamydomonas ikhephu kubushushu degrees 4 ngokukaCelsius sele abulawe. Kwacaca ukuba esi sityalo uyakwazi khona kwiqondo lobushushu ukuba aziqhelekanga lisiza njengesiqhelo.

Nanamhla oku, inzululwazi ayikwazanga ukuseka, ukuze ukuba izinto eziphilayo ezincinane kwiqondo lobushushu eliphantsi hayi kuphela asinde; kodwa ziyazala, nokugcina ukutya esebenzayo. eziphilayo ofanayo umhlaba de Wayehlatyelwe nto.

Yaye yintoni na isakhiwo?

Yintoni chlamydomonas snow? Iimpawu zale ummeli uhlobo lwesakhiwo monad ngenxa yokuba lona lisiza bangamalungu kwiseli enye. Umzimba iquka:

• amehlo;
• vacuole contractile.

movement iseli enikiweyo yomsila.

ephilayo maqanda, ngoko yemveliso mitospor ngenxa.

Vala ulwelwe ngemikroskopu glycoproteins kwakhiwa. Njengenxalenye eso sityalo enye kuphela chloroplast indebe-ezimile. I kernel nalo elinye kuphela.

Ingakumbi yokuhlala

Chlamydomonas fanele ku nezityalo ezimbalwa cryophilic. It uhlala khona, apho inshorensi ikhephu le ithatha unyaka wonke. Ixesha ekhula unyaka - ngeveki enye kuphela, ithuba ukufudumala kakhulu. Yokwandisa isityalo kufuneka amanzi avela ikhephu zaphela.

Ukuze chlamydomonas ukuba nande, yenza a elilodwa. Uninzi konyaka ukuba aleleyo, kodwa kamsinya nje isimo sezulu bekhululekile, iqala ukukhula koloni. Ngeli xesha, ikhephu kunye blushes.

amatyala umdla

Oku kutsale umdla omkhulu kwimeko yoluntu, nto leyo eyenzeka ngowe-1929. Ke lona lisiza yenyuka kule ndawo enkulukazi. Kwathi kwingxingwa BAS. Le ndawo sele wazalisa kwiikhilomitha ezimbalwa square kwintaba ephakame wamawaka amathathu eemitha.

Akukho kanye waphawula ngezenzeko umdla:

• e Northern the Urals;
• ku Franz Josef Land;
• kwi Arctic;
• Ena.

Famous kwakunjalo xa Chlamydomonas okhule Khakassia ngo-2015. "Khakassia" wafumanisa ukuba abasebenzi reserve. Ivatala snow ingxelo ngoJuni, 20. Ekumeni kakhulu ezintle wavula kufuphi shaman Ridge, ecaleni nechibi. Ukuphakama ngaphezu komphakamo wolwandle - malunga 1700 eemitha.

Kwaye enye into ke?

Chlamydomonas nivalis - hayi nje ulwelwe ummeli cryophilic. Phakathi kwezi nabo kuso:

• diatoms;
• cyanoprokaryota.

Le ukuvuseleleka zonke ezi ntlobo kwenzeka phantsi ziziphumo ezidibeneyo zinto:

• intabalala amanzi anyibilike;
• ukufumaneka izondlo kokusingqongileyo;
• ukukhanyisa;
• khona ulwelo zegesi lichithakale.

ukuba umdla

Iimvelaphi entsimini komhlana, kukho abahambi abambalwa abangenazo umnqweno ukuzama incasa bekhephu. Ke baninzi kufanele ayithandabuze; kwaye ayikho inetyhefu nto?

Izazinzulu zithi ungenza ngokukhuselekileyo uzame ivatala nekhephu ebomvu, nto ekhethekileyo kulo andiyifumananga. Kodwa ukuba kukho na kakhulu, kungenjalo kuya kubakho iingxaki kunye esiswini.

Lisiza in space

Njengoko siye safumanisa ngexesha imifuniselo ulwelwe cryophilic - isityalo singapheli kakhulu. Ayikwazi kuphela lukhona kwikhephu kunye zero kunye namaqondo sub-zero, eneneni, izinga iphile phezulu esithubeni.

Hayi kudala, olu hlobo micro-eziphilayo sele kufundwe kwi-ISS. Ukuze zokuhamba kwafuneka dewater lona lisiza, kodwa komzila iplanethi obekwe kwi neengcedevu zaso, ebonelela kwemiqathango kamnandi kakhulu. Le lokulinga yathatha iintsuku 450. Iisampulu kunikelwa emva uphila isithuba sangaphandle emva kumphezulu womhlaba, kungekudala ngokuqhelekileyo Yaphathana kwindawo eqhelekileyo.

Ngoku izazinzulu zinomdla indlela apho lona lisiza bakwazi ukuziqhelanisa neemeko ntshikilelo ezinjalo. Kukho kungenzeka ukuba ukucaciselwa kule nkalo iya kunceda ukuphuhlisa iindlela ezisebenzayo abantu. Kuthathwa ukuba kuya kuba luncedo kakhulu ngexesha lo moya.
