Euglena kore - shuka ko dabba?

Euglena kore - a guda-celled dabba, a samu a sabo ne m ruwa, Marshes, ramuka, puddles. A launi daga cikin abun ciki na jiki saboda babban adadin chloroplast a cytoplasm. Saboda haka, ga alama cewa ruwa "blooms" a lokacin da ɓarna, diluted euglena kore a cikin shi.

A tsarin shi kadan mafi wuya a lokacin da idan aka kwatanta da wani amoeba. Dukansu biyu suna da protoplasm da tsakiya. Duk da haka euglena kore wajen pellicle Layer ne har yanzu an rufe - wani m daina kai hare hare. The jiki yana da wani siffar kama wani dogara sanda, m a daya karshen da elongated - tare da wani. Daga cikin sako a gaba wajen ganye kananan flagellum. Akwai kuma mai haske ja "ido" cewa reacts da haske kuma, da ita taimaka cell a zabi shugabanci na motsi. Next zuwa shi ne vacuoles. Saboda da shãfe haske m harsashi na dabba siffar ba ma canja, mai yiwuwa ne kawai dan kadan, a cikin wasu iyaka, to damfara da kuma daidaita. Wannan tsarin Euglena kore haddasawa da kuma hanyar da na motsi. Flagellum yin rotational ƙungiyoyi, shi ne wani microscopic dabba wajen sauri iyon. Akwai jinsunan da cewa yin jiki undulation da haka taso kan ruwa. Me wannan ya faru ne ba a bayyana. Masana kimiyyar halitta da biyu shawarwari a wannan batun. A daya hannun, ƙila a sami wata dangantaka tsakanin wasu gabbansa da Euglena gina jiki filaments wanda su ne a karkashin pellicle kuma iya ji ƙyama. A daya hannun, da irin wannan yunkuri na iya haifar da gamsai secreted da cell.

Euglena ci kore Can da kuma dabbobi da shuka. A hanya, wanda shi nã zãɓen dogara a kan lighting. Its cytoplasm ƙunshi fiye da ashirin m Kwayoyin - chromatophores. Su ne, kamar yadda aka ambata a riga, da kuma stained Kwayoyin a kore. A da rana, ta amfani da chlorophyll kunshe ne a cikin chromatophores, kore euglena iya shiga a photosynthesis, carbon dacewa tana bukatar kazalika da shuke-shuke - carbon dioxide. Kamar wancan ne a cikin jiki daga inorganics kafa gina jiki kama sitaci da aka ajiye a cikin nau'i na hatsi a cikin cytoplasm. A dare, wannan cell za a iya powered a cikin wannan hanya a matsayin dabba. Shi ne iya yin amfani da vacuoles nan da nan sarrafa kwayoyin abubuwa a cikin kududdufai wanda riga isa a narkar da form. Saboda haka ya aikata da amoeba. Kuma da sakaci na kandami, da mafi daga cikin wadannan abubuwa more. Idan euglena kore shi ne a cikin duhu na dogon lokaci, da chlorophyll vuya daga chromatophores. Haka kuma, saka launi vuya da kuma keji, shi ne gaba daya decolorized.

Akwai nau'in da suke da kullum m photosynthesis, ba za su iya ci kawai dabbobi. Su ma ɓullo da wani irin mouthparts for ingestion na microscopic abinci barbashi.

Propagated euglena kore tsaye rabo daga cikin cell kanta: bayan da cytoplasm ne zuwa kashi biyu halves da core. Kowane mutum bayyana tsiro sabon flagellum. A karkashin sharadi gwargwado, Euglena kore bred sosai cewa ruwa ma zama dace launi. Akwai wasu irin wadannan guda-celled kwayoyin cewa an gwamnatin, remarkably saba da rayuwa ko a cikin sanyi. A sakamakon irin wannan karbuwa a lokacin da taro haifuwa snow fentin ba kawai kore, amma kuma a cikin ja, rawaya da kuma ko blue.

Akwai ma euglena wanda Kwayoyin suna cike da carotene. Suna fentin tafkunan ja ko ruwan kasa launi. .. Lokacin da kõguna a cikinta, kududdufai, Marshes, da dai sauransu bushe up ko daskare, kore euglena hasarar da flagellum, taso keya, an rufe tare da m harsashi - a lokacin da aka canza kama zuwa wani mafitsara. A wannan tsari shi za a iya jira sharadi gwargwado, a wuri guda, ko za'ayi tare da kura.
