I ka papa o nā flagellates, hui like nā mea ola e neʻe me ke kōkua o hoʻokahi a ʻoi paha flagella. Nui nā lunamakaʻāinana o kēia papa ma ke ʻano. Aia kēia mahele i nā kamaʻāina lehulehu o nā wahi kai a me nā wai kai, a me kēlā mau meaola a mākou e maʻa ai e kāhea i nā parasites.
ʻO nā palena a me nā ʻano o ko lākou mau kino ʻokoʻa. ʻO ka hapanui pinepine lākou i ke ʻano o ka hua manu, paukū ʻolokaʻa, kālī a pōpō paha. I ke kaʻina o ke ola, hoʻopiha ʻia nā kino o nā flagellates i nā ʻano huaola like ʻole, mai nā kulu wai o nā mea momona, nā glucogenes, starch, a pēlā aku.
Nā hiʻohiʻona, ke kūkulu a me ka nohona
ʻO ka lunamakaʻāinana maʻamau o kēia mau mea i ke ʻano ʻōmaʻomaʻo euglena. ʻO kēia mea maʻalahi hoʻokahi meaola hoʻokahi ka mea pohihihi i nā ʻepekema.
No nā makahiki he nui, ua hoʻopaʻapaʻa nā ʻepekema i waena o lākou e pili ana i ka mea nona kēia mea ʻano ʻē. Manaʻo kekahi poʻe ʻepekema he holoholona kēia, ʻoiai me kahi ʻano maʻalahi a liʻiliʻi loa. ʻO haʻi ʻē aʻe Kuhi ʻia ʻo euglena ʻōmaʻomaʻo i ka limu, ʻo ia hoʻi, i ka honua mea kanu.
Noho ʻo ia i loko o ka wai hou. ʻO nā puddle i hoʻohaumia ʻia, ka wai stagnant me nā lau popopo i loko o ia ka wahi punahele a kēia ʻelele o nā flagellates. No ka neʻe ʻana, hoʻohana ʻo Euglena i kahi flagellum hoʻokahi i mua o kona kino fusiform. Uhi ʻia ke kino holoʻokoʻa me ka pūpū o ka like paʻa.
ʻO ke kumu o ka flagellum i kāhiko ʻia me ka maka i ʻike maka ʻia, kahi ʻulaʻula ʻulaʻula i kapa ʻia he stigma. ʻO kēia peephole kahi māmā nui o ke kukui a kuhikuhi i ka euglena e ʻau i ke kukui maikaʻi loa i ka loko iʻa, kahi e hāpai ai i ka photosynthesis ʻoi aku ka maikaʻi.
Hoʻokomo pū ʻia ia me kahi vakuola pulsating, ʻo ia ke kuleana no nā ʻōnaehana hanu a me nā excretory o kēia mea. Ua like kēia me kekahi ʻōmaʻomaʻo amoeba a me euglena. Mahalo i kēia ʻōpala, hoʻopau ke kino i ka nui o ka wai.
Hoʻokomo ʻia kona ʻaoʻao ʻē aʻe me kahi nucleus nui, e mālama ana ma lalo o ka kaohi paʻa i nā kaʻina ola a pau o kēia mea ola. Loaʻa i ka cytoplasm o Euglena ka nui o 20 mau chloroplasts.
Lawelawe lākou ma ke ʻano he kumu waiwai o chlorophyll, e hāʻawi ana i ka euglena i kona kala ʻōmaʻomaʻo. He pane kēia i ka nīnau - no ke aha he ʻōmaʻomaʻo euglena no laila ua kāhea lākou. I kona kala, lanakila maoli ke kala ʻōmaʻomaʻo waiwai.
Eia hou, kōkua ka chlorophyll i kahi hana nui i ke kino o euglena - photosynthesis. I ke kukui maikaʻi, hānai kēia mea ola e like me kahi mea kanu maʻamau, ʻo ia hoʻi, autotrophic.
Me ka hoʻomaka o ka pouli, hoʻololi ke kaʻina digestion i kekahi manawa a hānai ʻōmaʻomaʻo euglena, e like me ka holoholona, pono ia i ka meaʻai meaola, nāna e hoʻolilo ia i meaola hypertrophic.
No laila, ʻaʻole i hoʻoholo ka poʻe ʻepekema iā wai ka mea e kū ai i kēia mea kū hoʻokahi - i nā mea kanu a i nā holoholona paha. Hoʻopili kāna cytoplasm i nā hua liʻiliʻi o nā mea mālama mālama, ʻo ka hoʻohui o ia mea kokoke i ka starch.
Hoʻohana ʻo Euglena iā lākou ke hoʻokē ʻai. Inā lōʻihi ka lōʻihi o ka euglena, ʻaʻole hiki ke hoʻokaʻawale i kāna mau chloroplasts. Ke hoʻomau nei ka hoʻokaʻawale ʻana i nā meaola unicellular ponoʻī. Hoʻopau kēia hana me ka puka ʻana o euglena, ʻaʻohe ona chloroplasts.
ʻO ke kino o ka ʻōmaʻomaʻo euglena he ʻano elongated, kahi e ʻoi ai kokoke i ka hapa hope. ʻOi ʻia kona mau palena - microscopic - ma kahi o 60 microns lōʻihi a ʻaʻole i ʻoi aku ma mua o 18 microns ākea.
ʻO ke neʻe ʻana o ke kino kekahi o nā hiʻohiʻona o euglena ʻōmaʻomaʻo. ʻAelike a hoʻonui ʻia e like me ka mea e pono ai. Loaʻa kēia i nā filament protein i loko hale ʻōmaʻomaʻo euglena... Kōkua kēia iā ia e neʻe me ke kōkua ʻole o ka flagellum.
Kāmaʻa Infusoria a me euglena ʻōmaʻomaʻo - ʻo kēia mau mea ola ʻelua i manaʻo ʻia he nui nā ʻano like o nā poʻe he nui. I ka ʻoiaʻiʻo, ʻokoʻa loa lākou. Hōʻike nui ʻia kēia i ke ala e hānai ʻia ai.
Inā hiki i ka euglena ʻōmaʻomaʻo ke ʻai e like me ka holoholona a me kahi mea kanu, a laila makemake ka ciliate i ka meaʻai maoli. Loaʻa kēia maʻalahi i nā wahi āpau. Hiki i kēlā me kēia kino wai piha ke piha i nā kamaʻāina maʻamau ʻole, e like me ka euglena ʻōmaʻomaʻo.
ʻO ke ʻano a me ka nohona
Inā ʻoe e nānā i ke ola o Euglena ʻōmaʻomaʻo ma o ka microscope, hiki iā ʻoe ke hoʻoholo he holoholona kolohe a wiwo ʻole kēia. ʻO ia, me ka hoihoi nui a me ka hoihoi, hoʻoweliweli i ka ciliate me kahi kāmaʻa a, me he mea lā, lawe mai kēia i kāna leʻaleʻa kupaianaha.
I ka hihia o ka euglena i waiho ʻia i ka pouli no kahi manawa lōʻihi, nalo loa ʻo ka chlorophyll, a lilo ia i kala ʻole loa. Hoʻopili kēia i ka hoʻopau ʻana o photosynthesis. Ma hope o kēlā, pono e hoʻololi kēia flagellate i nā meaʻai meaola wale nō.
Ke neʻe nei me ke kōkua o ka flagellum, hiki iā Euglena ke uhi i kahi mamao loa. I kēia hihia, ua kipi ʻia ka flagellum i loko o nā kahawai wai, e like me ka mea hoʻolele mokulele a i ʻole nā mokuahi.
Inā mākou e hoʻohālikelike i ka wikiwiki o ka neʻe ʻana o ka euglena ʻōmaʻomaʻo a me ka kāmaʻa ciliate, a laila ʻoi aku ka wikiwiki o ka mea mua. Kuhi mau ʻia kēia mau neʻe i nā wahi mālamalama maikaʻi.
Hiki ke hoʻonui i ka wikiwiki o ka euglena ma o ka hoʻohana ʻana i kahi holo, e kōkua ai i ka mea e kāpae i nā mea āpau e lohi i kāna ʻauʻau ʻana. ʻO ka hanu ʻana i kēia protozoan ma muli o ka omo ʻana o ka oxygen e kona kino holoʻokoʻa.
Hiki iā Euglena ke ola i nā wahi āpau, hiki i kekahi mea ola ke lili i kēia mākau. ʻO kahi laʻana, i ke kino o ka wai e hau no kekahi manawa, neʻe wale ka ʻōmaʻomaʻo euglena a ʻaʻole hānai, hoʻololi iki i kona ʻano.
Hāʻule ka huelo o ka protozoan, ka mea i kapa ʻia ʻo flagellum, a lilo ka euglena i pōʻai. Uhi ʻia me kahi pūpale pale kūikawā a hiki ke ola i nā wā maikaʻi ʻole. Kapa ʻia kēia ʻano he cyst. Hiki iā ia ke noho i kahi cyst a hiki i ke ʻano o nā kūlana o kāna kaiapuni nona.
Meaʻai kūpono
Inā e ulu ʻōmaʻomaʻo ana nā waihona wai, ʻo ia hoʻi he nui nā euglena ʻōmaʻomaʻo i loko o lākou. Mai kēia, ma ka huli, hiki iā mākou ke hoʻoholo he kūpono ke kaiapuni no ka mea maʻalahi, he mea kāna e ʻai ai. Mahalo i ka chlorophyll i loko o ke kino o kēia mea hoihoi, hiki ke hoʻololi ʻia o carbon dioxide i carbon a me nā mea ʻokanika i loko o nā mea inorganic.
ʻO kēlā ʻano mea kanu mea kanu o ka flagellate hiki ke pani ʻia e kekahi, kokoke i nā holoholona. Hana kēia i nā kūlana uila maikaʻi ʻole. ʻO ka mea pōmaikaʻi, ʻoi aku ka nui o nā meaola i loko o ka wai haumia, no laila ʻaʻole pōloli ka euglena ʻōmaʻomaʻo.
Hoʻopiʻi hou
Hana hou ʻo Euglena ʻōmaʻomaʻo ʻo ke ala asexual wale, kahi e hoʻokaʻawale ai ka mahele o ka māpuna makuahine i ka mahele lōʻihi i ʻelua mau huna kaikamahine. He mea pono e hoʻomaopopo ʻia ka hoʻokaʻawale metatic o ka nucleus ma mua o ka fission.
Ma hope o kēlā, hoʻomaka ka cell e hoʻokaʻawale mai mua. I kēia hihia, ke hoʻokumu ʻia ʻana o kahi flagellum hou a me kahi pharynx hou e kū nei, e loli malie ana. Pau ke kaʻina hana me ka hoʻokaʻawale ʻana o ka hope.
No laila, loaʻa ke kūkulu ʻia ʻana o ʻelua mau huna kaikamahine, ʻo ia nā kope kikoʻī o ka huna makuahine. Pili ka pae aʻe i ko lākou ulu ulu ulu. I ka wā e hiki mai ana, hana hou ʻia kahi kaʻina like o ka mahele.
