Hiki i ka 'āpana o nā limu' ōmaʻomaʻo ke hoʻokomo i nā mea kanu lalo a pau i loaʻa kahi meaʻomaʻomaʻo i loko o kā lākou mau keena - chlorophyll, mahalo i lilo ai ke keʻomaʻo i'ōmaʻomaʻo. ʻOi kēia ʻano ma kahi o 20 tausani mau ʻano ʻokoʻa. Hoʻolahalaha nā mea kanu me ka wikiwiki loa ma o nā kino wai a me nā wahi me kahi wai kiʻekiʻe, no ka laʻana, ma nā wahi pohopoho. Aia kekahi mau ʻano i wae i ka lepo, ka ʻili lāʻau, nā pōhaku kahakai i wahi no lākou e noho ai.
ʻO ka hui o nā limu ʻōmaʻomaʻo me nā unicellular a me ka koloneial. Ua hōʻike ʻia kahi noiʻi kikoʻī o ka benthos hiki ke loaʻa nā lunamaka'āinana multicellular. ʻO ke kū ʻana o ia mau limu i loko o ka wai e alakaʻi i ka pua. E hoʻihoʻi i ka hou a me ka maʻemaʻe i ka wai, pono ʻoe e hakakā i nā mea kanu, e luku loa iā lākou.
Thallus
He ʻokoʻa ʻo Thallus mai nā ʻano ʻē aʻe i kona kokoke maka i nā mea kanu ʻāina. Hana ʻia kēia ma ke ʻano he hopena o ka nui o ka chlorophyll. ʻO ka mea kupaianaha, hiki i ka nui o kēia mea kanu ke loli mai kahi mau millimeter a i 2-5 mau mika. Loaʻa nā mea kanu o kēia hui i nā ʻano thalli (papa).
ʻO ke kūkulu pūnaewele o nā limu ʻōmaʻomaʻo
ʻO nā pūnaewele āpau o nā limu ʻōmaʻomaʻo he ʻokoʻa. Uhi ʻia kekahi o lākou i ka pūpū mānoanoa, hana kekahi me ka ʻole o ia. ʻO ke kumu nui o nā hunaola āpau ke cellulose. ʻO ia ke kuleana no ke kiʻi ʻoniʻoni e uhi ana i nā hunaola. Ma ka hoʻokolokolo pono ʻana, ua loaʻa i kekahi ʻano laha ke kaula kaula, ka helu o ka flagella i loli i nā ʻano āpau. ʻO kekahi kumu ʻē aʻe o ka pūnaewele ke koloka. ʻO ka maʻa mau ʻike ʻia lākou e ko lākou hiʻohiʻona o waho - ʻano a me ka nui, akā maʻamau, ʻo ka hapa nui o lākou e like me ka mea like o nā mea kanu kiʻekiʻe. Ma muli o kēia, hoʻololi ʻia nā mea kanu i ka hana autotrophic o nā meaola. Eia naʻe, ʻaʻole hiki kēia i nā mea kanu āpau. Aia kekahi mau ʻano i hiki ke loaʻa i ka meaʻai ma o nā pūnaewele kūwaho - ʻo ia hoʻi, e komo i nā mea i hoʻoheheʻe ʻia i hoʻoheheʻe ʻia i ka wai. ʻO kahi hana ʻē aʻe a ka chloroplast e mālama nei i ka ʻike kūlohelohe, ʻo ia hoʻi, ka mālama ʻana i ka DNA o ka ʻaleka.
ʻO kahi mea hoihoi, akā hiki i nā limu ʻōmaʻomaʻo ke ʻano o nā kala. Aia nā mea kanu o nā kala ʻulaʻula a me ka ʻalani. Loaʻa kēia hoʻololi ma muli o ka hoʻonui ʻia o nā carotenoid a me nā pigment hematochrome. Aia nā limu ʻōmaʻomaʻo siphon i nā amyaplast aniani, i loaʻa ai ka starch. Ma waho o lākou, hiki i ka nui o nā lipids ke hōʻiliʻili i ke kino o ke kino. Ma ke kino o ka nui o nā limu aia kahi peephole i kapa ʻia, ʻo ia ke kuleana no ka hoʻohui ʻana i nā neʻe o ka limu. Mahalo iā ia e ʻumeʻume nā limu ʻōmaʻomaʻo no ka mālam.
Hoʻohua i nā limu
Ma waena o nā limu, aia kekahi mau ʻano me ka hānau kolohe a me nā mea ulu. Hiki i ka Asexual ma muli o ke kū ʻana o nā zoospores i ke kino o ka mea kanu; haki nā mea ʻē aʻe i nā ʻāpana liʻiliʻi, kahi e ulu ai kahi mea kanu piha. Inā mākou e noʻonoʻo i ke ʻano moekolohe o ka hana hou, a laila loaʻa iā ia ma ke ʻano he hopena o ka hoʻohui o nā gametes.
Noi a me ka hāʻawi
Hiki iā ʻoe ke hālāwai me nā limu ʻōmaʻomaʻo ma nā wahi āpau o ka honua. ʻO kahi helu nui o nā laha i kahi hana hoʻokele waiwai, no ka laʻana, i ko lākou alo, hiki iā ʻoe ke ʻike e pili ana i ka maʻemaʻe o ka waihona a me ka wai i loko. I kekahi manawa hoʻohana ʻia nā limu ʻōmaʻomaʻo e hoʻomaʻemaʻe i ka wai neoneo. Kūleʻa nui lākou i nā aquarium home. Ua maʻa nā māla iʻa i ka hana ʻana i ka meaʻai iʻa no lākou, a hiki i kekahi ke ʻai ʻia e kānaka. I ka ʻenekinia, hana haʻaheo ka limu ʻōmaʻomaʻo i kahi, no ka mea he mea kūpono ia no nā hoʻokolohua a me nā hoʻokolohua.
