ʻO nā lau nā ʻāpana nui o ka nui o nā mea kanu. Mahalo iā lākou, neʻe ka wai ma waena o nā mea kanu, ka hoʻololi ʻana o ka lā i ka ikehu ulu a me ka hoʻomaʻemaʻe o ka ea a puni. Nui nā ʻano meaolaola o nā lau e pili ana i nā ʻano like ʻole. I ke ana o kēia ʻatikala, e noʻonoʻo mākou i nā mea nui.
He aha ka lau?
ʻO ka lau ka waho o ka mea kanu a kuleana ʻo ia i ka photosynthesis, ka wai o ka wai, a me ka hoʻololi kinoea ma waena o ka mea kanu a me ke kaiapuni. Loaʻa lākou i ka hapa nui o nā mea kanu, mai ka mauʻu ʻike ʻole ʻia i nā kumulāʻau nunui. Ma ka huaʻōlelo "lau," kiʻi koke ka manaʻo i kahi lau kuʻuna, e like me ka birch. Eia nō naʻe, nui nā ʻano like ʻole o nā kinona a me nā hoʻolālā, lawelawe nā mea like i nā kumu like.
ʻO nā ʻano nui o nā lau
Hoʻokumu ʻia ka maʻalahi maʻalahi o ka lau o nā mea kanu i ko lākou kinona. Wahi a ia, aia nā hana e like me ka lau (ʻo kahi laʻana, ma ka ferns), nā lau o nā mea kanu pua (ke ʻano kahiko me ka petiole a me ka lau lau), nā nila a me nā lau wahī (maʻamau i nā mea kanu).
ʻIke ʻia e nā wahi ma ke koʻokoʻo
ʻO kahi hoʻonohonoho hoʻololi a hoʻonohonoho hoʻonohonoho paha e hoʻomaka ka lau e ulu ma ke kumu, hoʻokahi no kēlā me kēia pona. ʻO ka huaʻōlelo "knot" pili i ka wahi ma ke koʻokoʻo i hoʻohana ʻia e hana i kahi lau hou.
ʻO ka hoʻonohonoho ʻē aʻe e ulu ana nā lau ʻelua i kēlā me kēia pona o kahi lālā a i ʻole koʻokoʻo. Eia kekahi, i nā manawa he nui, hoʻohuli ʻia kēlā me kēia node 90 kekelē e pili ana i ka mea ma mua.
Hoʻonohonoho Rosette i nā lau i ko lākou wahi ma ke kiʻekiʻe a me ka hoʻonohonoho ʻana i ka pōʻai. ʻO ka ʻōlelo maʻamau, ulu nā lau āpau o kahi mea kanu mai kahi kiko (aʻa) a hana i kahi ulu lāʻau nani.
Aia kekahi hoʻonohonoho hoʻokamakama. Me he mea lā ka ʻaoʻao ʻē aʻe, akā ʻekolu ona lau ma ka piko. I kēia hihia, ua kapa ʻia nā piko he whorls a hiki ke hoʻololi ʻia hoʻi i 90 kekelē.
Hoʻohui ʻia e ke ʻano o nā lau lau
Hoʻokumu ʻia kēia hoʻonohonoho ʻana ma ka helu a me ka mahele o nā lau e ulu ana ma hoʻokahi ʻoki, a mai hoʻokahi pona o ke koʻokoʻo (kumu). No laila, ʻo ka maʻalahi maʻalahi ka lau maʻalahi. Hoʻohālikelike ʻia e ka loaʻa ʻana o hoʻokahi lau lau a hoʻokahi petiole. ʻO ka pā ponoʻī ka papa o ka lau, ʻo ia hoʻi kona "canvas" me nā veins. I kahi lau maʻalahi, hiki ke loaʻa i kekahi ʻano, akā ʻaʻole hiki i nā ʻokiʻoki i ka petiole. Hāʻule mau nā lau o kahi ʻano maʻalahi me ka petiole, me ka waiho ʻole i kahi ʻāpana o ka lāʻau.
ʻO ka ʻano aʻe he pepa hui. Ma aneʻi, hoʻopili ʻia kekahi mau lau i hoʻokahi petiole i ka manawa hoʻokahi. Eia kekahi, hiki i kēlā me kēia o lākou ke loaʻa kahi petiole hou.
Nā ʻano lau e like me ko lākou kinona
ʻO ka hoʻonohonoho ʻana e ka lau lau ka laulā. Ma hope o nā mea āpau, aia he heluna nui o nā mea kanu me nā lau lau like ʻole. Aia ma loko o kēia papa inoa nā inoa he 30, e wehewehe ana kēlā me kēia i kekahi ʻano kikoʻī. ʻAʻole mākou e papa inoa iā lākou āpau, e ʻōlelo wale mākou e pili ana i nā mea maʻamau.
Maliʻa paha ʻo ka ʻano i kamaʻāina loa i kēia hoʻokaʻina ʻana, ʻo ka thyroid. ʻO kahi laʻana, he lau ko ka birch o kēia ʻano. ʻIke lākou e like me kahi pale liʻiliʻi a loaʻa i kahi lau lau kuʻuna. Aia kekahi mau ʻano ʻē, e like me ka "puʻuwai hope". Loaʻa i kēia ʻano ke ʻano o ka puʻuwai elongated, me ka lalo, ʻoi loa ka hopena e pili ana i ka petiole.
Hoihoi nō hoʻi nā lau ʻōkalakala. ʻIke ʻia kēia ʻano i nā ʻano mauu āpau a me nā pua he nui. ʻO ke ʻano "dissected pinnately" e kamaʻāina i nā mea āpau mai ka wā kamaliʻi - he lau ka dandelion o kēia ʻano.
Hoʻolālā lau lau ʻole
I ka papa o ka evolution, ua loli ka lau o nā kumulāʻau a me nā mea kanu i nā hoʻololi like ʻole. I ka hapa nui o nā lunamaka o ka flora, ʻaʻole lākou i alakaʻi i nā loli koʻikoʻi, akā naʻe, ua hoʻomaka nā lau o kekahi mau mea kanu e hana i nā hana kikoʻī.
Māhele hei
Maliʻa paha ʻo ka "loea nui" ka hopu ʻana i nā lau. Aia lākou ma nā mea kanu ʻai ʻole e ʻai i nā mea kolo. ʻO kahi laʻana kūpanaha ka sundew a i ʻole Venus flytrap. ʻO ka hana nui o ia lau ka hopu ʻana i ka pepeke, hōʻoia i ka paʻa ʻana o ia mea, a hoʻowali iā ia me ke kōkua o nā ʻenemi kūikawā. ʻOkoʻa ke ʻano o ke kiʻi ʻana: i kekahi mau hihia, hoʻopuka ka lau i ka wai kōpō (sundew), a i nā mea ʻē aʻe e pani koke (Venus flytrap), a i nā mea ʻē aʻe, nā pōpō kūikawā me nā nū (pemphigus) e pāʻani.
Nā lau ʻono
Hoʻonohonoho ʻia kēia ʻano lau e hana i nā waihona wai. ʻO ka mea kanu i kamaʻāina loa iā lākou ka ʻaloe. Mānoanoa a momona, piha ka nui o ka wai i loko, no ka mea, ulu kēia mau pua i nā wahi maloʻo me ka ua liʻiliʻi.
Lau ʻūlū
Mālama pū kēia ʻano i ka wai, akā ʻaʻole ia ma muli o ka mānoanoa o ka pulp, akā e hoʻohana ana i kahi funnel. Hoʻokumu ʻia ka funnel e ka lau ponoʻī, e wili nei i kahi ala kūikawā a mālama i ka wai ua ua hōʻiliʻili ʻia.
Kakala
No ka pale, ua loli ka lau o kekahi mau mea kanu i ke kākalaioa. Hiki iā lākou ke hoʻololi i ka lau lau, paʻakikī a kuhi, a i ʻole hiki iā lākou ke hana mai nā wana.
ʻUmi ʻumiʻumi
Loaʻa nā lau o ka ʻumiʻumi i nā mea kolo e pono ai ke kākoʻo. He mea hoʻonui lākou o nā ʻāpana luna o nā lau maʻamau i ke ʻano o nā kaʻina lōʻihi, ʻōwili. Pili lākou i nā mea a puni, i hoʻopuni ka mea kanu iā lākou. ʻIke ʻia kēia ʻano lau i nā pi māla, kukama, a me nā paukū.
Nā Phillodies
ʻO Phillodies kahi hihia kūikawā o ka ulu ʻana o ka petiole. ʻO kēlā petiole e like me ke ʻano o ka lau a hiki i ka photosynthesis. I ka manawa like, aia kahi pepa maoli i kahi mamao aku i kahi hanana maʻalahi a me nā degrades.
Pākuʻi
Hoʻohālikelike ʻia kēia ʻano lau e ko lākou ʻano semicircular a pōʻai hoʻi, pinepine me ke kūkulu ʻana i kahi ʻūlū liʻiliʻi. I ke kaumaha i hoʻokumu ʻia, ma ke ʻano he rula, aia nā lau o kahi ʻano ʻokoʻa a i ʻole nā inflorescences.
