Chlamydomonas nivalis: mbali structural, malo okhala

Amazing ndi wapadera zojambula zina zochitika padziko ife. Mwachitsanzo, nthawi zina pali zokongola, zokongoletsa chodabwitsa, yotchuka lotchedwa "vembe matalala". Kuzipangitsa chlamydomonas chisanu, thupi kakang'ono, lomwe ndi chinsinsi kwa ambiri.

Ndipo adzakuuzani asayansi?

Ngati ife titembenukira kwa zamoyo, mukhoza kuona kuti chlamydomonas chisanu sayansi otchedwa Chlamydomonas nivalis. zomera m'dziko la algae lapansi. Ngakhale kupenta chisanu pinki ndi ngakhale kufiira, zimagawidwa monga wobiriwira.

bakiteriya The imapezeka mu madzi, adzaupereka kwa zomera zokhala ndi selo imodzi. chakuti ndere wobiriwira umabwera pa expanses achisanu yofiira ndi, chifukwa kukhalapo mu akuphatikizapo a pigment, lotchedwa "astaxanthin". Kuwonjezera izo, mbewu zizindikiro pigment wobiriwira, ndipo - ngakhale ophunzira kudziwika chlorophyll.

Pamene chlamydomonas chisanu Mitundu, kunena za "ukufalikira matalala". The pamalo kupeza mthunzi wabwino wa pinki, ndipo nthawi zina infernal wofiira, ngati chikhalidwe recreates zithunzi ndi mantha kanema.

Chlamydomonas nivalis wa okonda ozizira. Izi ndere - amasiyana kotheratu kalasi zambiri za thermophilic zomera unicellular.

Gawo

Kelp mu zamoyo ano akhoza kuchitika kwa mtundu Chlamydomonas, a m'banja la dzina chomwecho. Izo, nawonso, ndi mbali ya ndondomeko, amatchedwa "volvoxes". The gulu la zomera nalo dzina lake chifukwa pigment ali mu zamoyo, umatchedwa "chlorophyceae". Msinkhu ngakhale apamwamba kuimira - dipatimenti. Chomera wa algae wobiriwira. Pomaliza, ufumu mbewu.

mapiri okongola

Popeza chlamydomonas chisanu pa kutentha pafupi ziro akuona mapiri kwambiri ndi ofufuza kumpoto ndi mwayi kuwona chithunzi chokongola.

Zodabwitsa ndizakuti, pinki - osati mthunzi chisanu mkulu mu mapiri. foci zimapezekanso:

• wofiirira;
• wofiira;
• zofiirira;
• chikasu.

Chifukwa maluwa wa chisanu - ukukhala mu izo tosaoneka zomera.

Amwalira chlamydomonas chisanu pa madigiri 4, kotero kuona malo okongola ndi okhawo anthu amene sali owopa cha kuzizira.

Nthawi zambiri zazikulu kupenta pinki mtundu zingaoneke:

• mu Antarctic;
• mu Caucasus.

Ngati inu kuchotsa pamwamba wosanjikiza, likukhalira kuti mkati woyera chisanu. Izi zimachitika chifukwa cha kulunjika ya moyo wa zomera zachilendo - ". Chlamydomonas matalala" Habitat algae - yekha pamwamba wosanjikiza.

Kodi zimenezi zimachitika?

Kudzikundikira pigment pinki si monga choncho, ndipo mchikakamizo cha zinthu kunja. Ukufalikira kumayamba pamene mpweya ndi wotentha. M'chigawo yachibadwa mu mbewu chipale chivundikiro ndi matalala, koma pamene dzuwa akuyamba konzekera, wosanjikiza M'mwamba thawed, ndi zinthu mulingo woyenera kubalana. Koma zimatenga kanthawi kochepa, chifukwa chlamydomonas chisanu pa kutentha madigiri 4 Celsius kale aphedwe.

Kukhala pa nthawi yoyenera mu malo oyenera, apaulendo angaone udakali wotanganidwa ting'onoting'ono algae. pigment The amasonkhana msanga. Kuphunzira zodabwitsazi, ofufuza anatenga zitsanzo wa chisanu, ndiyeno kufufuza za m'kati mwa Kutentha kwa kutentha kusungunuka. Iwo anafotokoza kuti madzi pa liwiro mkulu chindithandize utoto particles. Aliyense wa iwo - izi ndi mbewu zosiyana.

si zoonekeratu zoonekeratu

Lero, climber, akuyenda, ulendo membala, kukhala m'gulu la expanses achisanu, ngati wamagazi, si mantha kapena kudabwa ndi zodabwitsazi, koma amakonda anatsegula pamaso pake wokongola kwambiri woterewu. Koma si nthawi zonse, chirichonse chinali momwemo.

Mpaka posachedwapa, anthu matalala ofiira anali weniweni chinsinsi. nthano angati akhudzana ndi! Only kanthawi pang'ono zapitazo, asayansi asanaganize zimene ndicho chiyambi cha chodabwitsa lapansi. Ndere anapezeka ku Arctic ndi Antarctic. Anapeza kuti amaona tizilombo zabwino zikhalidwe za okwera mkulu, kupanga njuchi yapangidwa m'mapiri.

Lero, akatswiri kale mitundu 140 ya algae ndi zamoyo zina, amatha yopatsa ndi chisanu wosangalatsa, choyambirira, zobwera mtundu.

Nature kachiwiri kudabwa

Pamene sayansi anagwira algae tosaoneka ofufuza anadabwa, chifukwa chlamydomonas chisanu pa kutentha madigiri 4 Celsius kale aphedwe. Kunapezeka kuti mbewu akhoza kukhalapo pa kutentha amene sizionekaoneka algae mwachizolowezi.

Mpaka lero, sayansi sanazindikire, kotero kuti tizilombo timeneti pa kutentha otsika sangakhoze kukhala moyo, komanso kubereka, kukhala ndi kagayidwe yogwira. Similar zamoyo padziko lapansili mpaka zinawululidwa ayi.

Ndipo kodi kukonza?

Kodi chlamydomonas chipale? Maonekedwe a nthumwi za mtundu wa dongosolo monad chifukwa chakuti algae a unicellular. thupi la:

• diso;
• contractile vacuole.

selo kayendedwe anapereka bakiteriya udzakhalire.

Asexual chamoyo, kotero kubalana ndi chifukwa mitospor.

Phimbani tosaoneka algae anapanga glycoproteins. Monga mbali ya mbewu ali chimodzi chokha chikho woboola pakati chloroplast. Ngale ndi chimodzi chokha.

Kulunjika malo okhala

Chlamydomonas wa ochepa zomera cryophilic. Kamakhala kumeneko, kumene chisanu chivundikiro kumatenga chaka chonse. Nyengo kukula kwa chaka - mmodzi sabata, nthawi kutentha kwambiri. Chifukwa kuswana mbewu akusowa madzi chipale kusungunuka.

Kuti chlamydomonas akhoza kuchulukitsa, ndipamene zygote. Kwambiri kwa chaka ndi matalala, koma mwamsanga pamene nyengo afika bwino, amayamba kukula njuchi. Panthawi imeneyi, chisanu ndi blushes.

Nthawi chidwi

Iwo anakopeka chidwi chachikulu pa nkhani ya onse, zomwe zinachitika mu 1929. Ndiye algae wamkulu pa m'dera lalikulu. Izo zinachitika pa chiphaso Bass. Njuchi chadzadza ochepa makilomita lalikulu pamalo okwera mamita zikwi zitatu.

Osati kamodzi anati chidwi zochitika:

• mu Urals kumpoto;
• pa Franz Josef Land;
• mu Arctic;
• Kamchatka.

Wotchuka zinalili pamene Chlamydomonas chakula Khakassia mu 2015. "Khakassia" anapeza iwo anali antchito a m'dera limeneli. Vembe chisanu anauzidwa mu June, 20s. The malo okongola kwambiri anatsegula pafupi Ula lokwera, pafupi m'nyanja. Kutalika pamwamba pa nyanja - za 1700 meters.

Ndipo chimene chirichonse iwo?

Chlamydomonas nivalis - osati nthumwi cryophilic algae. Mwa iwonso a:

• diatoms;
• cyanoprokaryota.

Kudzutsidwa mitundu onsewa amapezeka pansi zotsatira kuphatikiza zinthu:

• kuchuluka Sungunulani madzi;
• kupezeka kwa zakudya mu chilengedwe;
• kuyatsa;
• kukhalapo mu madzi mpweya kusungunuka.

ndi chidwi

Wagwidwa munda maluwa, pali apaulendo ochepa amene alibe kufunitsitsa kuyesa kukoma kwa chipale chofewa. Koma ambiri molondola adakayika: ndipo si chakupha izo?

Akatswiri a sayansi amanena mukhoza bwinobwino kuyesa vembe ndi chisanu wofiira, palibe wapadera mu izo sanapezeke. Koma sipangakhale kwambiri, mwinamwake padzakhala mavuto ndi mmimba.

Ndere mu mlengalenga

Monga ife tinapeza pa zatsopano cryophilic algae - chomera Hardy kwambiri. Sikuti alipo mu chisanu ndi pa ziro ndi kutentha boma ziro zoona, mlingo kupulumuka ndi mkulu ngakhale mu mlengalenga.

Si kale, mtundu wa yaying'ono-zamoyo wakhala anaphunzira pa ISS. Zoyendera anayenera dewater algae, koma mu kanjira wa dziko la anaikidwa trays, yomwe imapereka zinthu ndi omasuka. kuyesera unatenga masiku 450. Zitsanzo anapulumutsa pambuyo akukhala m'mlengalenga ku padziko lapansili, posakhalitsa bwinobwino zimaŵetedwa ku malo bwino.

Tsopano asayansi chidwi zimagwirira imene algae anatha kuti azolowere zinthu zimenezi nkhawa. Pali kuthekera kuti zikumveka pa mbali imeneyi kudzakuthandizani kukhala njira zimene zimagwira ntchito kwa anthu. Iwo amaganiza kuti adzakhala zothandiza makamaka mu nthawi ya ndege.
