Chlamydomonas nivalis: izici kwesakhiwo, ukukhahlamezeka kwendawo

imidwebo Amazing futhi eyingqayizivele ngezinye izikhathi kubonakala ezweni elisizungezile. Ngokwesibonelo, ngezinye izikhathi kukhona egqamile, lomkhuba tebuciko, eyaziwa ngokuthi "ikhabe iqhwa". Nokukubangela chlamydomonas iqhwa, umzimba ezincane, okuyinto imfihlakalo eziningi.

Futhi ukuthi uzokutshela ososayensi?

Uma siphendukela biology, ungabona ukuthi iqhwa chlamydomonas kwezesayensi ngokuthi Chlamydomonas nivalis. Lesi simila, elingelakwaJuda lona lisiza. Naphezu Umdwebo iqhwa pink ngisho libomvu, libhekwa njengoba oluhlaza.

Lesi silwanyana itholakala kuphela ngamanzi agobhozayo, lingelikaJehova izitshalo owumphumela. Iqiniso ukuthi alga oluhlaza iza phezu expanses seqhwa elibomvu, ngenxa yokuba khona e oyiyo ukwakheka kombala, ngokuthi "astaxanthin". Ngaphandle-ke, lesi sitshalo yakhiwa sombala oluhlaza, futhi - ngisho abafundi chlorophyll ezaziwayo.

Lapho chlamydomonas iqhwa izinhlobo, khuluma ngezinto "iqhwa ukuqhakaza". I evele ibe umthunzi nice pink, futhi ngezinye izikhathi baba bomvu Infernal, sengathi imvelo idale izithombe kusuka ibhayisikobho ethusayo.

Chlamydomonas nivalis kungokwalabo abathanda abandayo. Lokhu alga - uhluke ngokuphelele isigaba eminingi ye thermophilic izitshalo unicellular.

ngezigaba

Kelp eziphilayo zanamuhla kuyothwalwa kuyiswe uhlobo lwe Chlamydomonas, omndeni of the gama elifanayo. It yena, iyingxenye inqubo, kubhekiselwa kuzo 'njengamadoda volvoxes ". Ikilasi lezi izitshalo lethiwa ngenxa sombala eziqukethwe eziphilayo, ubizwa ngokuthi "chlorophyceae". Liphakeme ngisho nakakhulu inani sesigaba - mnyango. Lesi sitshalo kungokwalabo ulwelwe oluhlaza. Ekugcineni, kuba umbuso isitshalo.

izintaba zakhona ezinhle

Njengoba chlamydomonas iqhwa at okushisa eduze zero azizwa bezintaba omkhulu nabahloli bamazwe enyakatho ekude nethuba ukubona isithombe esihle.

Phela, pink - hhayi kuphela umthunzi okusezingeni eliphezulu iqhwa ezintabeni. foci ayatholakala:

• onsomi;
• obomvu;
• onsundu ngaphansi;
• aphuzi.

Isizathu sokuba zezimbali iqhwa - ophila kuwo izitshalo ezincane.

Dies chlamydomonas zeqhwa 4 degrees, ngakho ukubona indawo enhle kuphela labo bantu asesabi emakhazeni.

Isikhathi esining impela Umdwebo omangalisayo pink umbala kungabonakala nasemkhakheni:

• e-Antarctic;
• eCaucasus.

Uma ususa le ungqimba top, kuvela ukuthi ngaphakathi eqhweni elimhlophe. Lokhu kwenzeka ngenxa ngokucacile zokuphila zalesi sitshalo engavamile - ". Chlamydomonas iqhwa" Habitat ulwelwe - kuphela ungqimba ebusweni.

Kwenzeka kanjani lokhu?

Ukuthola sombala pink akunjalo nje, futhi ngaphansi kwethonya kwezimo zangaphandle. Ukuqhakaza kuqala lapho umoya wakhona ufudumele. Esimweni esejwayelekile cover iqhwa plant ithule, kodwa lapho ilanga liqala ukuxoxa, ungqimba engenhla ukuthi incibilikiswa, futhi kwezimo ezifanele ukuze sizale. Kodwa kuthatha isikhashana, ngoba chlamydomonas iqhwa ezingeni lokushisa 4 degrees Celsius wabulala kakade.

Ukuba ngesikhathi esifanele endaweni efanele, isihambi zingabuka ulwelwe amancane asebenzayo futhi umatasa. Lo mbala aqoqana ngokushesha. Ukutadisha lokhu mkhuba, abacwaningi wathatha amasampula eqhwa, bese kuhlolwa ngesibonakhulu ngu Ukushisa lokushisa ukuncibilika. Kuyaphawuleka ukuthi emanzini ngejubane elikhulu uqale ukunyakaza izinhlayiya ngokubomvu. Ngamunye wabo - lena isitshalo ehlukile.

non-sobala esobala

Namuhla, umgibeli, othatha, ilungu uhambo, liphakathi expanses seqhwa, sengathi igazi, akuyona zesaba noma kusimangaze lokhu mkhuba, kodwa uyakujabulela wavula phambi kwayo yinhle kakhulu ngendlela engavamile. Kodwa ngaso sonke isikhathi, konke kwakuyize kanjalo nje.

Kuze kube muva nje, abantu iqhwa obomvu kwaba imfihlakalo real. ezinganekwaneni Bangaki ehambisana nayo! a kuphela isikhashana edlule, ososayensi esiphethweni uyini umsuka lomkhuba. Ulwelwe watholakala e-Arctic nase-Antarctic. Futhi wathola ukuthi uzizwa nezilwanyana ezincane okuhle nemibandela ezindaweni eziphakeme kakhulu, okwenza leli koloni ithuthukiswe izintaba.

Namuhla, izazi zezinto eziphilayo kakade kwadingeka 140 zama-ulwelwe kanye nezinye izinto eziphilayo, uyakwazi uzipha iqhwa kumnandi, yokuqala, umbala nemvelo.

Nature futhi bamangale

Lapho isayensi wabamba le ulwelwe ngesibonakhulu, abacwaningi bamangaliswa, ngoba chlamydomonas iqhwa ezingeni lokushisa 4 degrees Celsius wabulala kakade. Kwatholakala ukuthi lesi sitshalo uyakwazi khona emazingeni okushisa ukuthi aziyona into evamile lona lisiza evamile.

Kuze kube namuhla, isayensi ayikwazanga ukusungula, ukuze la magciwane ezincane ashisa ongaphakeme abakwazi kuphela ukusinda, kodwa futhi kukhiqize, balondoloze umzimba esebenzayo. Okufanayo eziphilayo emhlabeni kuze Kwakubonakalisiwe cha.

Futhi iyini isakhiwo?

Kuyini chlamydomonas iqhwa? Izici yalesi omele uhlobo lwesakhiwo monad ngenxa yokuthi ukuthi ulwelwe basonta unicellular. Umzimba yakhiwa:

• iso;
• vacuole contractile.

iseli ukunyakaza enikeziwe msila.

umzimba Asexual, ngakho imifanekiso mitospor ngenxa.

Cover ulwelwe ezincane kwakhiwa glycoproteins. Njengengxenye isitshalo has eyodwa kuphela chloroplast inkomishi emise. Ikhenela futhi eyodwa kuphela.

Ngokucacile kwendawo

Chlamydomonas kungokwalabo izitshalo ambalwa cryophilic. Cishe ihlala khona, lapho isembozo iqhwa ihlala unyaka wonke. Ukutshala inkathi ngonyaka - isonto elilodwa kuphela, isikhathi yokufudumala enkulu. Ukuze ukuzalela simila idinga amanzi kusuka iqhwa elicibilikile.

Ukuze chlamydomonas ungase uphindaphinde, it yakha zygote. Iningi ngonyaka zingabantu ithule, kodwa ngokushesha nje lapho isimo sezulu uthola ukhululekile, iqala koloni ukukhula. Ngalesi sikhathi, le iqhwa kanye blushes.

amacala ezithakazelisayo

It bakhangwa intshisekelo enkulu leli cala yomphakathi, okuyinto eyenzeka ngo-1929. Khona-ke lona lisiza wanda ngezinga le ndawo enkulu. Kwathi ngaleso pass Bass. I koloni uye wagcwalisa amakhilomitha square ambalwa endaweni engamamitha amamitha ayizinkulungwane ezintathu.

Hhayi yake yaphawula izenzakalo ezithakazelisayo:

• eNorthern Urals;
• ku Franz Josef Land;
• e-Arctic;
• EKamchatka.

Famous kwakunjalo lapho Chlamydomonas kwanda Khakassia ngo-2015. "Khakassia" wathola ukuthi base nabasebenzi esiqiwini. Watermelon iqhwa kwabikwa Juni, 20s. I namathafa amahle kakhulu wavula eduze Shaman khahlamba, eduze kwechibi. Ukuphakama ngaphezu kogu lolwandle - mayelana 1700 amamitha.

Futhi yini okunye bangaphi labo abakumangalelayo?

Chlamydomonas nivalis - hhayi kuphela omele ulwelwe cryophilic. Phakathi kwalezi futhi basonta:

• diatoms;
• cyanoprokaryota.

Awakening of zonke lezi zinhlobo kwenzeka ngaphansi Umthelela ohlangene yezinto:

• ngokuchichima amanzi ncibilika;
• ukutholakala umsoco imvelo;
• ukukhanyisa;
• khona in the ketshezi yamagesi siphela.

kumnandzi

Caught ensimini ehlotshisiwe, kukhona abavakashi ambalwa abangenayo isifiso ukuzama ukunambitheka iqhwa. Kodwa abaningi kufanele bangabaza: futhi akuyona ezinesihlungu ke?

Ososayensi bathi ungazama ikhabe neqhwa obomvu, lutho ekhethekile ke ayitholakalanga ngokuphepha. Kodwa ngeke ibe khona kakhulu, kungenjalo kuyoba nezinkinga nge esiswini.

Ulwelwe emkhathini

Njengoba sithole phakathi ucwaningo ulwelwe cryophilic - isitshalo eziqinile kakhulu. Ngeke zigcine khona iqhwa at zero okushisa sub-zero, eqinisweni, izinga lokusinda kuphezulu ngisho isikhala.

Akunjalo kudala, lolu hlobo amagciwane ibilokhu wafunda ku-ISS. Ukuze zokuhamba kwadingeka ukuba dewater lona lisiza, kodwa emzileni iplanethi afakwe emathileyi, esihlinzeka izimo kuqhathaniswa ukhululekile. Ukuhlolwa yayithatha izinsuku 450. Amasampula zilethwe emva abahlala emkhathini emuva ebusweni iplanethi, ngokushesha ngokuvamile ezifuywa endaweni ajwayelekile.

Manje ososayensi banesithakazelo izindlela lapho ulwelwe bakwazi ukuzivumelanisa nezimo ezinjalo ukucindezeleka. Kukhona kungenzeka ukuthi ukuzwakala kulesi sici kuzosiza ukuthuthukisa izindlela ezingasetshenziswa yibo abantu. Kusolwa ukuthi kuyoba usizo ikakhulukazi isikhathi indiza.
