Euglena green kana muti kana mhuka?

Euglena green is a unicellular animal found in fresh, reservoirs, marshes, ditches, puddles. Mucherechedzo wemuviri uyu unokonzerwa nehuwandu hwehuwandu hwekloroplast mu cytoplasm. Nokudaro, zvinoratidzika kuti mvura "inotumbuka", kana yakanyanyisa kubhurwa euglena.

Chimiro chayo chinenge chakaoma kunzwisisa, kana uchichienzanisa ne amoeba. Zvose izvi zvine protoplasm uye nucleus. Zvisinei, euglena ruvara rwekunze huripo hunofukidzwa nehupamhi hwe pellicle - chidimbu chinoputika. Mutumbi une chimiro chakafanana nechinokanganisa, chisina maturo pane imwe mugumo uye chinoparadzaniswa - kubva kune imwe. Chidiki chiduku chinobuda kubva kuodzwa mwoyo pane imwe nzvimbo yekare. Panewo "tsvuku" yakatsvuka iyo inopindirana nechiedza uye nokudaro inobatsira sero kusarudza nzira yekufamba. Kurutivi rwayo ndiyo vacuole. Pamusana pekudzivirirwa kwegomba rekunze, chimiro chemhuka hachichinje zvakanyanya, chinogona kungopindira, zvishoma, mune imwe nzvimbo, uye kururamisa. Ichi chimiro euglena green chinogadzirisa nzira yekufamba. Kubhururuka kwemhepo kunofamba, zvisikwa izvi zvisingashamisi zvinoshambira zvakakurumidza. Kune marudzi akasiyana-siyana anoita kuti muviri uwedzere-kufanana uye kudonha. Chikonzero nei izvi zvichiitika zvisati zvajeka. Biologists vane mafungiro maviri pamusoro peizvi. Kune rumwe rutivi, panogona kuva nekubatana pakati pe euglena organelles nemakanda emaprotini ari pasi peiyo uye anogona kubvumirana. Uye kune rumwe rutivi, rudzi urwu rwekufambisa runogona kukonzerwa nehutu hwakavanzwa nesero.

Eulgene inogona kudya zvinyoro zvose semhuka uye semiti. Nzira yaanosarudza inobva pakudhenzi. Mune protoplasm yayo ine miviri inopfuura makumi maviri evhavha-chromatophor. Ivo, sezvatotaurwa, uye varaira cage muhomwe . Mumazuva masikati, kushandisa chlorophyll iri mune chromatophores, euglena yeguru inokwanisa kugoverana muyotoriynthesis, iyo inogadzirisa kabhoni inoda pamwe chete nemiti - kubva ku carbon dioxide. Muchiitiko ichi , muviri unoumbwa mumutumbi wayo kubva kune zvinhu zvisingaenzaniswi , zvakafanana nemashizha uye zvinowanikwa mumhando yezviyo mu cytoplasm. Usiku, sero iri rinogona kudyidzwa nenzira imwechete semhuka. Iyo inokwanisa, nekubatsira kwekudzivirira, kuisa pakarepo zvirongwa zvehupenyu, izvo mumvura midzi yakawanda kakatovhiringidzwa. Ndizvo zvakaitawo amoeba. Uye zvakanyanya kukanganwa dziva, kunyanya kwezvinhu izvi. Kana euglena ruvara rwuri murima kwenguva yakareba, chlorophyll kubva ku chromatograph inonyangarika. Saizvozvowo, ruvara runonyangarika kubva muchitokisi, runonyatsotsanangura.

Kune zvipenyu izvo zvisingawanzi photosynthetic, zvinongodya chete semhuka. Vanotanga kunyora chimiro chakanaka chokumedza kuedza microscopic foods particles.

Mikana yekusarudzwa nemuviri weiyo nzira yekudya kunovaka zvakare inoratidza kune masayendisiti kuti mhuka nemiti zvinotangira.

Euglena inowedzera kuburikidza nekureba kwemajeri esero pachayo: mushure mokunge protoplasm inoputika kuva mahafu maviri uye nucleus. Munhu mumwe nomumwe mutsva anokura itsva flagella. Mumamiriro ezvinhu akanaka, green euglena yakazara zvokuti mvura inowedzerawo mararidzana. Kune mhando dzakadaro dzezvipembenene izvi zvisikwa zvekuti zvinenge zvichishanduka, zvakanyatsogadziriswa kurarama kunyange muchando. Somugumisiro wekugadziriswa kwakadaro munguva yekuberekwa kwavo kwemahombekombe, chando hachisi mavara chete muhuzha, asiwo mune tsvuku, tsvuku uye kunyange bhuruu.

Uyewo pane euglens, masero ayo akazara ne carotene. Vanonyora dziva mumvura yakatsvuka kana yebhuruu. Apo nzizi, maruva, maruva, nezvimwewo, zvinomira kana kusvibiswa, euglena ruvara runorasikirwa nemiti, inotenderera, inofukidzwa nehombodo yakaoma-inogadziriswa kuva cyst. Mune chimiro ichi, chinogona kumirira mamiriro ezvinhu akanaka munzvimbo imwechete kana kutakurwa pamwe neguruva.
