Brown ka līoho: he manawa pōkole ano o ka 'Oihana

Brown ka līoho i laulā pae o ka mea kanu i noho kuhikuhi ma ka meaola wai. I ka lā, ewalu wale ikeia? Ueony, i loko o ka papa o ka evolution ua hoʻoneʻe i ka freshwater hana kūpono.

Oihana Kelp: kino hale

na lala a pau o keia oihana i multicellular kino - koloniala a me unicellular ano o ke ola ka mea, e hoikeia. Like no ka nui, ka mea hiki e loa okoa - e like lau hiki e microscopic, a hiki mau mika ma ka lōʻihi. Ike makahiki meaola mea kanu, akā, aia no kekahi poe e noho mai i ka makahiki 18.

Inā mākou e kamailio e pili ana i ke kinona a me ka 'ole o ka thalli, he mea i' ano au. limu kino e komo o filaments o nā papa, mau eke, crusts a uuku lāʻau liʻiliʻi. I ka kūpapakū mea paʻa a me ka mea kanu Via pau a rhizoids kahua.

Integument poe ma ka halepaahao paia, a IeAUPIIe, IAa IO he mau papa (ekolu mau papa, a he 'elele). Ka mawaho aloha, ahu iho ninoieoʻano nui o ka pectin waiwai, a me na sulfated polysaccharides. I ka pahale loko, ahu iho, he bulk o kelulose olona.

Borax līoho: ke kelepona hele 'ole

An nui ano o ke kahua hoʻonohonohoʻana keena o ke alo o plastids. Nā 'elele o keia pae ana o mea kanu, kēlā halepaahao he he nui helu o ka mea uuku loa-ulu chloroplasts. Plastids i ehaʻili lahilahi. Nō kāu, i ka pāʻili lahilahi o ka chloroplastʻili lahilahi hele i loko o ka endoplasmic reticulum paha nucleus. Like no ka chlorophyll, maanei ka mea, ua hōʻike ano A, C1 a me C2.

Eia hou, na plastids o ka līoho he fucoxanthin, violaxanthin, zeaxanthin a me ka Hoʻokolohua-carotene, i mea i nui ka ano no Plant Taxonomy.

Ke aeea nucleus He hoʻokahi wale nō, eia nae, aia nō kekahi nunui-? Ueo. I ka papa kuhikuhiE huahana o ka hoʻokoe hrizolaminarin i ua waihoia ma ka hana kūikawā vacuoles a me cytoplasmic granules.

Kelp a me nā'ōlelo

Me ka Poeikohoia o keia oihana hiki ke hoʻopulapula vegetatively, nā kiʻie a asexually. Ma ka hapanui o? Ueony, cloning ua lawe mai ma ka mahele ana i ka thallus. Akā, no ka laʻana, ficus ma ka poli o ke kino, he mea kekahi pūʻulu o ka hana kūikawā aeee i hiki huli i loko o ka hou thawed ka wā pono.

Like no ka mea asexual kaʻina, loa pinepine ka mea, ua lawe mai ka mea o zoospores. Wale i kekahi mau? Ueo paʻi ma ka mea o ka paa Mono a tetraspor. Ma ke ala, zoospores a me gametes - ka wale ke ano o ke ola flagellates kelp.

Like no ka mea moe kaʻina hana, e hiki ia:

• Isogamous (sperm a me nā hua i ka ia nui).
• Heterogamic (kane a me ka wahine gametes i okoa gametes).
• Oogamnym (kane gametes i ka poe liilii, a me ka lawe lima, oiai na wahine oogonia noho wahi a me kekahi mau nui nui).

A puni ka 80s o ka 20th kenekulia i ua wehe ae ia i kekahi mau Nine Inch pee ma ke kino iloko o ka moe līoho ulu. Kēia mea, aohe mea e like pheromones,ʻeleu palapala i mau a hiki i kēia lā.

Kelp a me ka hapanui loa-ikeia laʻelaʻe 'ia

Kekahi o ka loa loa-ike? Ueo ua noʻonoʻo kō kelp, a me ka limu. I ka mea kanu i ka nui dissected thawed, ka lōʻihi o ka i hiki e mai 1 a hiki i 14 mau mika. Ke thallus kükulu i ka nui o ka nui laminarin. Eia hou kekahi, limu ua noʻonoʻo i ka waiwai kahi o ka iodine. Ma kekahi'āina, ua kanu ua mahi, a 'Imi hoʻohana ma salads a me nā kīʻaha. O Tal no hoi e ai 'i hoʻohana ma o ka iapaau ana o ka thyroid maʻi.

Ke genus Sargassum mea i lohe nuiʻia, no ka mea, ua ku pono ia i ka paakiki, lōʻihi thalli o kēia mau mea kanu i ka wai Sargasso Sea i ka manawa, uaʻoi aku pilikia no ka 'auʻau' ana.
