Euglena uliuli - mea kanu a holoholona?

Euglena uliuli a pau - he hookahi-aa? Holoholona, i loaʻa i loko o hou stagnant wai, wahi lepo wai, auwai, puddles. Ke ano o ka maʻiʻo o ke kino ma muli o ia ka helu nui o chloroplasts i loko o ka cytoplasm. Nolaila, ia mea i ka wai "blooms" ka wā excessively nāu kekahi euglena uliuli a pau i loko o laila.

Ke 'ole ia he uuku oi paakiki ka wā like ai i ka amoeba. Ua o ia i ka protoplasm, a me ka nucleus. Eia naʻe euglena uliuli a pau mawaho o ka pellicle, ahu iho ua no uhiia - he'ōlewa wahī. Ke kino i ke ÿano o ua like no me ka kālī, kūmūmū ma kekahiʻaoʻao, a elongated - me kekahi. Mai ka recess ma ke alo mai o ka lau liʻiliʻi flagellum. Aia ka hoi i ka alohilohi ulaula "maka" i reacts e hoomalamalama, a ilaila kōkua i ka halepaahao i ka olelo o ka neʻe e koho. Next no ka mea, o vacuoles. Aie i ka mea i hoʻopaʻaʻia i pā iwi o ka holoholona shape ua kūpono kou hoʻololi ole, ka mea e wale kānaka, i loko o kekahi mau palena, e oOeEIAOO a straighten. Kēia 'ole o Euglena'ōmaʻomaʻo kumu a me ka aoao o ka neʻe. Flagellum hoʻokō i rotational neʻe, mea he microscopic oia, aole i koke 'auʻau' ana. Aia nā laha 'ana e ke kino undulation, a pela lana. No ke aha la keia hana mea i maopopo. Biologists i mau manaʻo kōkua i loko o keia pili ana. Ma ka kekahi lima, aia i e ka pilina ma waena o organelles a me Euglena kumuʻiʻo filaments a mea ma lalo o ka pellicle a me ke emi. Ma ka kekahi lima, i kēia 'ano o ka neʻe i ke kena ae la ia e mucus pee ma ka halepaahao.

Euglena ai launahele e, a me ka holoholona, a me ka mea kanu. Ka papa hana, i ka mea, e wae mai hilinaʻi nui i kau iho. Kona cytoplasm he oi aku iwakalua ka'ololaha keena - chromatophores. Ka mea, e, e like me ua oleloia, a ua hookohu aku keena ma uliuli. Ma ka auina la, hoʻohana 'chlorophyll na ma chromatophores, omaomao euglena hiki ke komo i loko o kāʻamaʻai, kalapona assimilating nele like nō hoʻi ia me nā mea kanu - o carbon dioxide. Pela i loko o kona kino, mai inorganics i hana i ka nutrient ua like no me pia, a ua waiho ia ma ka palapala o ka mānoanoa ko loko o ka cytoplasm. I ka po, keia halepaahao hiki ke mana ma ka like me ka holoholona. He hiki no ka hoʻohana vacuoles koke hoʻokō 'ke aloha' ona i loko o nā Reservoir i mua lawa i ka mea hoʻoheheʻe palapala. No laila, e hana ana i ka amoeba. A me ka ole o ka loko, i ka nui o kēia mau waiwai hou. Inā euglena uliuli a pau o loko o ka pouli, no ka lōʻihi manawa, i ka chlorophyll nalo mai na chromatophores. Alaila, coloration ke kino a me ka hīnaʻi manu, ka mea, ua pau decolorized.

Aia i? Ueo i mea nui ku pono kāʻamaʻai, ka mea hiki keʻai wale nō holoholona. Ka mea, i nui ke ano o ka mouthparts no ka 'ai, inu ka microscopic ai (particles).

Choice o keia kino, ua hiki ia i ka mana hookahi manawa hou i ka 'ai i kānakaʻepekema i na holoholona a me nā mea kanu i ka ia kumu.

Hoʻopulapula euglena omaomao lonikū mahele o ka halepaahao wale: ma hope o ka cytoplasm ua maheleia i mau halves a me ka Kora naʻEsau. Kēlā me kēia kanaka iʻikeʻia ulu hou flagellum. Ma lalo o 'ano kūpono, Euglena'ōmaʻomaʻo piha iho nei, ua nui ia i ka wai i kūpono waihoʻoluʻu lilo. Aia nō kekahi mauʻano o kēia mau mea hookahi-aa? Meaola i i Hawaiʻi, remarkably hakuloli e noho a hiki i ke anu. E like me ka hopena o ia ka hoʻololiʻana i loko o ka manawa o ko lākouʻaha'ōlelo hau pena ole wale uliuli a pau, akā, i loko o kaʻulaʻula, he lenalena, a hiki uliuli.

Aia mau no hoi euglena kona keena, ua piha o ka carotene. Ka mea, i pena loko ulaula a eleele waihoʻoluʻu. .. I na muliwai, loko, wahi lepo wai, etc. hoʻomaloʻo nō wau i 'ole ahau, uliuli euglena nalowale ka flagellum, ua hoʻokōʻia, uhi me ka manoanoa iwi - ma ka manawa ia iho i loko o ka cyst. Ma keia palapala ia e kali no ka 'ano kūpono ma ka ia wahi a lawe a me ka lepo.
