Lalo mea kanu

Ke 'ano o ka a puni flora' epekema i hookaawale ai i loko o nā subkingdoms: kiekie ae, a malalo mea kanu. E nā kiekie kanu, ka vegetative kino i ua maheleia i loko o nā loko, ka mea, i anei, na aa a me na lau. Ma lalo mea kanu, ma ka mea ku ole, e like me ke kaawale ana ua ole, eia hoi, he mea ole multicellular reproductive nā loko. Ma kēia kālaimeaola i ka lalo kanu pili wale ka līoho, akā, he mau makahiki aku nei, i aku la ia ia i ke koko, me fungi a me koʻohune, e like me nā mea a pau meaola'ē aʻe ma mua o kiekie mea kanu a me nā holoholona.

No ka haahaa mea kanu i wehewehe aku e: heʻano o nā waihoʻoluʻu a pau, hookahi-aa? Reproductive nā loko, ka wai kaianoho koholā. Ka līoho ma luna o mākou Honua hiki mua: i ka makahiki o ka wāwahie mea kanu i loaʻa i loko o ka papa o Archean a me Proterozoic au, i kahi o 3 ieeeea makahiki ..

Kekahi, hoʻomālama ma ka inoa, manao ana haʻahaʻa mea kanu - primitive hookahi-aa? Microscopic nui. Naʻe, i kēia mea,ʻaʻole oiaio. O ka holo ana, hookahi-aa? Līoho no a hiki i keia subkingdoms, akā, e pili no hoi i ka poe nui multicellular līoho, ka lōʻihi o ka i kekahi mau umi o mika ihoiho. Like pono me kiekie, ka mea hiki ke komo i loko o ke kaʻina hana o ka kāʻamaʻai. ka līoho Propagation ia lŘlŘ moe a me ka asexual (vegetative ole zoospores) 'o ia hoʻi. A pau i ka lalo a luna kanu pihaʻi me chlorophyll, akā, ma lalo ma ka hou ka mea, he 'ē pigments e haawi ia i kekahi mau' ano:ʻeleʻele, yellowish, ulaula, etc.

Lower mea kanu, examples

Ka līoho hiki ke maheleia i meaola a me freshwater (ka hapanui). Lower mea kanu i noho i loko o ka wai, hiki ke kai piha a elua ma ka ili, a ma ka hohonu. Eia naʻe, no ka mea, ola ka mea e pono ai ka malamalama, no laila, i nui hohonu - ma kahi o 250-300 mika a oi - ka mea, e hele mai i nā kāʻei i ka la mau kukuna mai i komo iloko ma ka wai kolamu.

Ke loa kaulana kai kelp - kelp a me ka limu. He He haiki kuina, ae hiki aku i ka lōʻihi o kekahi mau mika a me ka hoopaa ana i ka lalo-keʻano o ka hanaʻana rhizoids. Hoʻopulapula kelp zoospores - keena, he palapala reminiscent o ka ohia, na ka nucleus a me chromatophores, i hoʻolako pono me ka flagella no ka neʻe. Ma hope iho o ke kala o ka makuahine aeea zoospore ka dukima flagella, neʻe i loko o ka wai a hiki i ka mea e paʻa ai i ka nutrient kūpapakū, a e ole haawi aku ke ola i ka hou ka līoho.

Bladder - kekahi ano o ka moana kelp. Kēia multicellular kanu kohu i ka laau, kona lōʻihi hiki a hiki i elua mau mika. Fucus pili i ka nutrient kūpapakū ma na puupuu wawae, pinepine ho okumu i ka pau o ka ulu lāʻau ma ka Hawaiian wai. Ua Ua hoʻopulapula nā kiʻie: i loko o kekahi maternal aeee i kapa antheridia, a aia ma luna o nā kihi o nā mea kanu i hana sperm i loko o nā keena - oogonia - hana oocyte. Ma lalo o ka aoao o attractants - 'ona e,ʻo ka wai i loko o ka sperm i na hua paha, ka mea, coalesce a me ka zygote ua hanaia, mai a e ulu hope o ka hou ka līoho.

I freshwater Reservoir haʻahaʻa kanu (līoho) i kānāwai. Ka loa, he pono ole no ia - Spirogyra. Spirogyra ua easiest loaʻa ma loko o ka stagnant ka wai: ao alohilohi i uliuli bitumena ho okumu i he mau huhui like slimy hulu hipa. Inā 'oe e nānā i ka mea ma lalo o ka microscope, e hiki ke ike thallus mea kanu, oia hoi o ka nui (i ia 0,01 mm) paukūʻolokaʻa keena holo ana ma ka lālani. Spirogyra hiki ke paʻi i nāʻaoʻao: nā kiʻie a vegetatively. Haʻalele fucus, kona ho okumu i ka zygote ia lŘlŘ ke kuʻi nukeliu o sperm a me ka hua manu, keia līoho zygote ua hanaʻia ma ka huina 2 keena. Vegetative propagation ia lŘlŘ i anaʻe o na filaments ma keia hihia, kēlā me kēia māhele ua hana i ka hou laau.
