Generative nā loko o nā mea kanu: pua, ka hua a me ka hua. Pehea e KamakawiwoʻOle mea kanu

generative nā loko o nā mea kanu - mea he pua, hua a me ka hua. Ka mea, i na mea kanu moe nā'ōlelo. Ma keia 'atikala, e kūkākūkā mākou i kēlā o kēia mau kino.

ka pua

Loa nui generative hui, o ka flowering mea kanu - ia mea he pua. He ua ka Hoʻololi 'pōkole hoi e pana aku, a lawelawe' ana i ka reproductive nā loko, i nā mea a pau mea kanu, akā, wale ma angiosperms. He mea hoihoi i loko o generative nā loko o flowering mea kanu - ia ka hoʻonaʻauao 'ana, i ua aia ma luna o ka peduncle. Wahi palena manawa ka inoa o ka pua ōhāhā. Eia nō nā māhele a pau o ka pua, ke kumu nui o ka a - ka pistil a me stamens. Ka mea, i ke aupuni 'o ka waena. Nā stamens nō ke kāne kino, a me ka wahine - ka pistil. Hope i hookuu ninoieo o ka ovary, mika a me ka stigma. Ke ovary i ovules, i ua hana a oʻoʻana i ka hua. Anthers a staminate ka pae - na eiiiiiaiou o na stamens. Ua loaʻa nā anthers o ka pollen ai kahi sperms i hana.

perianth

Angiosperms flowering mea kanu no hoi i ke perianth. No ke aha lāʻo ia e pono ai? Kēia mea,ʻaʻole i ka generative nā loko o angiosperms, akā, kona lau ka na māhele o ka pua hoʻopale ai. Sepals i kapaia kona kino mawaho, lau, IeAUPIIe, IAa IO omaomao. Ka mea i hana i kekahi kiaha. Corolla ua hana mai o ka pā petals. Perianth ua kapaia pāpālua ina ia he ana o ka corolla a me ka calyx a me ka hemahema hoi - ina mea ua i mai o ka ia lau. Pālua ano o Hilo Hanakahi, pea a me ka kamako iki. A me he mea he mea ma ka lilia a me ka tulip. Perianth mea e pono ai,ʻaʻole wale i ka pale aku i ka māhele o ka pua, loko, akā, e,ʻo kekahi pollinators. I mea no ke aha no laila, pinepine wehewehe aku e aahu'ōniʻoniʻo ia ia. Perianth i loko o ka makani-pollinated mea kanu i pinepine hoemiia. No hoi, ka mea hiki ke poe e Film a me ka unahi (popela, Aspen (CO), wilou, a me ka birch, kiliala).

nectaries

Nectaries kapaia kūikawā glands i i kekahi angiosperms flowering mea kanu i loko o kā lākou mau pua. Mau glands pee laulau puaʻa sugary wai i kapaʻapapane. He mea pono ia,ʻo pollinators.

Monoecious a dioecious mea kanu

No laila, i ka generative nā loko o ka mea kanu pili ia pua. Aia he mau ke ano o ka pua no ke alo o ka pistils a me stamens. Kēlā mau mea kanu i nā kekahi me ka kekahi, kapa monoecious (kaʻukama, hazel, lāʻauʻoka, palaoa). Inā na pistils a me stamens i hōʻike mai iā ia ma luna o kekahi mea kanu, ka mea i kapaia dioecious (buckthorn, wilou, wilou, popela maka).

inflorescence

E hoomanao i kēia manawa i ka inflorescence. Ke kanu hiki e kekahi lehulehu uuku a nui hookahi pua. Small, lawe pū, ua kapaʻia inflorescences. Ka mea, ua oi conspicuous i pollinators, e like me ka pono pollinated e ka makani. Kekahi mau okoa ano o inflorescences. Eia ka mea, ua.

'ano o nā inflorescences

• Pepeiao - heʻano i mea ano o ka mea kanu, ma ka papa kuhikuhi o nā koʻi lipi o i mea sessile pua (me peduncles).
• Aia Ua hoi he Ka Uluwehi O Ke pepeiao. Ua Ua hana ia e hoʻohuiʻia i kekahi mau mea (examples - rai, me ka hua palaoa).
• Cob - heʻano inflorescence, pua noho, kahi o ka a ua wehewehe aku ma ka manoanoa kikowaena kumu (kekahi laʻana - calla).
• Palaki - o ka wā o nā pua e ma lalo iho, kekahi ma hope o kekahi ma luna o kekahi, he pono ole iho (axis). Ano he kumu hoʻohālike - cherries, līlia (kiʻi ma luna).
• Aia mea no hoi kekahi ano o ka inflorescence, e like me ka hīnaʻi. Ua Ua wehewehe aku, ma ka nui, no ka dandelion a me ka chamomile. Ma keia hihia, ke saucer-hoʻokinoʻia naʻe mau iho (axis) ua hoonohonoho i ka nui helu o nā pua e noho hoʻopuni ana.
• Head - kekahi hana hoihoi type. Ua Ua wehewehe aku ma ka mea ana i nā pua uuku i sessile spherical truncated ma ka iho (axis) (clover).
• Aia Ua hoi he mea mamalu (e like, ahiahi primrose a cherries). Ma keia hihia, no ka nui iho (axis) (truncated) pua i aia ma luna o ka mea ia lōʻihi lalo iho.
• Akā, ma ka parsley a carrot inflorescences makana i ka pau pūʻulu iloko olaila o ka poe noonoo ole umbrellas. Kēiaʻano ua kapaia he luna 'mamalu.
• Akä naÿe i ka palaki kiai ma na pua i loko o ka hookahi pelane. Nolaila, pedicels, a hohola aku, mai ka kikowaena (axis), i ka okoa loa a (na ohia, yarrow).
• Panicle inflorescence mea he luna 'me ka mau kīloi paʻewa mau lala, a iloko o ka puapua, brushes (lilac, ota etc.).

Part o na pua i loko o kekahi inflorescence ninoieo o kekahi wale no o ka corolla. Ma nā hua'ōlelo, nā stamens a me pistil ka mea nele. Ia mea, no ka mea hoike, i ka 'ole o nā pua o ka mea kanu? Ueo e like me pua nānālā a daisy (kiʻi ma luna).

Moe nā'ōlelo o nā mea kanu

Generative nā loko o nā mea kanu - pua, hua, a me ka anoano. I mea e hana i ka hua e pono ai i ka pollen, Aia ma luna o nā stamens, hoʻoneʻe i ka stigma. Ma na olelo e ae, he mea pono e loaʻa pollination. Ma ka hihia ma ka pollen mea ma luna o ka stigma o ka ia pua, he mea pakiko-pollination (palaoa, peas, mohihi). Akā, ia mea pinepine ole ia. Ma ka hihia o ke kea-pollination stamens aia ma luna o ka pollen o kekahi mea kanu ua hoololiia a hiki i ka stigma o kekahi'ē aʻe. Pehea ia loaʻa i laila? Pehea mea kanu paʻi? E ka maka ia.

nā moku halihali mokulele o ka pollen

A me ke olonā i maloo pollen hiki o laila 'o ia makani (birch, hazel, alder). Nā pua i ka makani-pollinated kanu i IeAUPIIe, IAa IO uuku, pelupelu ia i loko o inflorescences. Ka mea, i kekahi poorly ulu ai 'ole-existent perianth. Pollen, eia hoi, ke lawe nā mea kolo. Ma keia hihia i kapaʻia nā mea kanu Entomophilous. Kēia kaʻina hana ke komo 'ana a me nā manu, a hiki i kekahi mau mammals. Nō kāu, na mea kanu puaʻala, lei, loaʻaʻapapane. Ma ka hapanui o na hihia, ka pollen Padfolio, ka mea, he kūikawā appendages - lou.

I kona ike aku i kekahi kanaka hiki i halihali pollen, ma o na la ia i stamens ae ma ka stigma. Ma keia hihia, ua kapaia kea-pollination. Ua Ua hoʻohana 'ia, ma ka nui, e hoʻoikaika' i ka hua a? Iecaianoaaiiie o houʻano likeʻole o nā mea kanu.

kane gametophyte

Pollen mānoanoa, hoike mai ia iā mākou me pollen - o ke kane gametophyte, a ua hanaʻia i loko o ka stamens. I ka haku mele 'ana o kēia mau mānoanoa ko i mau keena - generative a me ka vegetative. Ka mea mua i hana sperm - kane wahine keena.

Female gametophyte

Ma ovule, pistil ovary ma ka hana wahine gametophyte. Ua ua kapaʻia heʻewalu embryo sac. Kēia gametophyte nae ho kekahi aeea ma i loaʻa he 'ewalu haploid nuclei. Kekahi o ia mea ma mua o ko Salisbury mau ka 'ē aʻe. Ua Ua kapaʻia ia i hua manu, a ua aia ma ka pyltsevhoda. Aia nō kekahi mau liʻiliʻi nuclei, i mea ma ka waena. Ka mea, i kapaʻia ka Central Kora naʻEsau.

Ke kaʻina hana o ka fertilization

Inā ka stigma loaʻa pollen vegetative aeea hoʻomaka e ulu i loko o ka pollen Tube. Ma keia hihia ko ia neiʻoniʻoni i ka generative halepaahao micropyle (pyltsevhodu). I ka hope elua sperm komo i ka embryo sac. E like me ka hopena, fertilization ia lŘlŘ. Ke zygote Ua hana ka wā o ka ovum me fused kekahi o spermatozoa. Mai keia hua embryo laila e hoʻomōhala ai. Like no ka lua o sperm, ia merges me ka Central Kora naʻEsau (e like me oe i hoomanao, elua o ia). Pela i hana triploid endosperm o ka hua. Ua accumulates ka mahuaola. Testa i hana mai uhi ovule. Kēia mea he papalua fertilization kaʻina. Ua Ua wehe e S. Navashin, Lūkini botanist, i ka 1898. Hua i hana mai kekahi o ka hoomaka paia o ka ovary, a no kekahi mau māhele 'ē aʻe o ka pua.

generative kanu nā loko nā, e like me 'oe ke ike, a me ka hua o ka hua. Pōkole hōʻikeʻano o kēlā me kēia.

hua

I ka haku mele 'ana o ka hua kikowaena hua kapa komo, endosperm, a me ka germ. I waho aiiay huna kona testa i lawa ke anuanu. Ka mohala i ka spine, gemmule, ōhāhā, a me cotyledons, i ka mea kanu i ka embryonic lau mua. Inā ka embryo i kekahi cotyledon, he mea kanu i kapaia monocots. Inā i ka mau o ka ia - bipartite. ʻO ka mahuaola i hookuu i loko o ka endosperm ole cotyledons (kūikawā pūnaewele nā'aʻaʻa). Ma ka hope hihia, na cotyledons aneane ulu.

ka hua

He Heʻano luna '' ole, i ka i hanaia'na hiki komo, koe waleʻai, a me kekahi mau māhele 'ē aʻe o ka pua: no ka wahi, i ke kumu o na sepals a me petals. Hua, i hana mai mauʻai i kaʻohiʻana (blackberries, raspberries).

Ua pono e olelo mai la i ke kinona o ka hua ka loa like. He He okoa helu o na anoano. Ma keia kumu kālā līkaia no odnosemennye hua a me ka poe mamo. Keia mea aie a hiki i ka helu ana o ovules i loko o ka ovary. Dala i kekahi maloʻo a me ka juicy hua.

No laila, ua ho'ākāka 'ia ma mākou i ka generative nā loko o nā mea kanu. Ma ka hopena, ua wehewehe pehea e hoʻopulapula hua a me ka hua. Like no ka pollen e ka hailonaʻana ka mea, i kau aʻela ma luna.

Puunaue ana o na anoano a me ka hua

He mea hoihoi i loko o generative nā loko o nā mea kanu (hua a me ka hua), hohola, k pōmaikaʻi? Ueo a me dispersal o ka mea kanu. Ka mea hiki ke kaʻi aku ma luna o lākou iho, i mea typical no ka laha 'e like me ka lenalena, he laau, impatiens, lupine, lila, geranium. Na hua o kēia mau mea kanu, e crack ka wā oo, a me ka mana e hoolei i ka anoano o ka mamao 'ano lōʻihi. Ua puunaue iaoiaeii ua kapaia avtohoriey.

Ka makani hiki i hali ka hua. Oia kekahi kaʻina ua kapaia anemochore. Hydrochory memo ina ma ke kaʻina hana o laila 'o ia hapa wai ornitohoriya - manu zoochory - holoholona. Ia ano i lawe kanu anoano, a i ka hua juicy. Ma ka hope pinepine hoʻomōhala slinging ole Padfolio waiwai (burdock, etc. succession.). Kēia ka poʻea pau i ka laha ana o ka mea kanu. Man Radio no hoi he mau manamana nui. No kekahi 'kona kanawai i kanu dispersal i loko o nā manawa, a mahuahua nui launa pu, ma waena o nā' âinapuni a me na aukanaka a pau.

No laila, ua kamailio e pili ana pehea e hoʻopulapula mea kanu. E like me 'oe ke ike, i ke kaʻina mea he luna'. Aka hoi, ia mea nui ka hoʻokō.
