'O ke kino kino. 'O ka'ōpena o ka mea kanu ka pilina?

'O kēlā me kēia'ōpena lā'au i kona iho hi'ohi'ona ho'ohālikelike e pili pono i nā'oihana i hana'ia. No laila, ke hā'awi nei ka pepa i ka pulupulu, a me ke kumu - maika'i ka lepo. He pua ka pua, a ua hua'ia kahi hua me nā'ano'ano. Ma kēia'atikala e nānā kākou i nā hi'ohi'ona o kā lākou physiology a me ke kuleana i ka ola o nā mea kanu.

He aha ke kino?

Hiki ke kapa'ia ke kookoo wale nō ka papa hana o ka mea kanu, i hana'ia e nā'ano like'ole. Eia kekahi la'ana, he kumu alaka'i, mechanical, education and integumentary. Akā,'o nā ha'awina o nā algae i ka nānā wale ke nānā aku e like me nā'ano o lalo. 'O ka'oia'i'o, ua kau'ia lākou he seti o nā hi'oko'a like'ole, i ho'ohui'ia me ka anatomically wale nō. No laila,'a'ole hiki ke no'ono'o'ia kēia hale e ke kino.

E no'ono'o i ka papa o nā angiosperms ki'eki'e. 'O ko lākou kino honua, e like me ka mea i'ōlelo mua'ia,'o ia ke kumu. Aia ma kahi o ka honua kahi pakele. Aia ia me kahi'āpana axial - ke kuhi, a me ka'ao'ao'ao'ao. I ke ka'ina o ka ulu'ana, ua ho'okumu'ia ka pua ma luna o ke kī, kahi e ulu ai ke pēpē.

Nā'ano o nā mea kanu

Ho'opili'ia nā'ōpena o nā'ano kanu e like me nā hō'ailona'ē a'e. Ma nā'oihana i hana'ia, ke'ano o ka vegetative a me ka hānau. 'O ka hui mua ke kumu a me ka pakele. 'O ka mea mua, hana lākou i ka hua kanu vegetative, a he mea hiki ke kūpono ma muli o ka'oki'ana o ka hui nui o ka'ōpoko holo'oko'a. Hiki ke mālama'ia e nā a'a, nā kōpoki, nā'oki'oki, nā lau, nā pūpū. Mālama nā mea kanu lā'au i nā hana'ē a'e i loko o ka mea kanu. 'O kēia ke'ano o ke ki'i'ana, kahi'oihana lepo, ulu, lawe wai a me nā mineral.

Pono'ia ka mea kanu no ka mea kanu e hana i ka hana pilina. 'O kēia'ano kope o kā lākou'ano he waiwai nui. 'O ka manawa wale nō o ka ho'opili'ana i ka wahine'o ka recombination o nā mea ola, kahi hopena o ka mea hou, pono mau,'ike'ia nā hō'ailona. Ma muli o kēia, ua hiki i ka mea kanu ke ho'ololi i nā'ano hou o ke ola.

'O ka'ōpena o ka mea kanu ke'ano

I ke ka'ina hana o ka ho'opi'i wahine, nā ho'okomo i ka hana. 'O kēia mau pūnaewele kūikawā aia i loko o nā'ōpū, i kapa'ia he generative. He pua ka pua. I ke kū'ana o ka ulu'ana, ua ho'ohua'ia kekahi hua, kahi e ulu ai nā'ano'ano. 'A'ole hiki ke'ano o ia'ano ho'ohui kino no nā mea kanu a pau e hiki ke hana hou i ka hana. Eia kekahi la'ana, hiki i nā loina unicellular i lalo o nā hihia kūpono ke hana i nā mea hō'ailona. Hele lākou i loko o ka wai a ho'opa'a i nā pālua. 'O ka hopena, ua ho'okumu'ia he zygote. Ua uhi'ia me ka iwi pa'apū a ma kēia'ano e luhi ana a maloo. Ke hele hou'ia nā kūlana maika'i, ua māhele'ia nā mea o ka zygote i'ehā mau motile spores.

I nā mea kanu i'oi aku ka ki'eki'e, ua ulu nā pūnaewele male i nā'ōpani kūikawā, i kapa'ia he gametangia. I loko o nā kinipuna, aia lākou ma luna o ka ape o ke kolo a loa'a ke'ano o ka hana oval. A no nā'ōpū he male kāne a me wahine gametophytes i ho'okumu'ia ma kahi lā'au - e ulu ana. 'O nā pua a me nā spermatozoa'ele'ele i nā manawa like'ole, no laila ke'ano o ka hui'ana i waena o nā mea kanu like'ole. Pono nā mea kanu a pau i ka wai no ka ulu'ana. 'O kēia hi'ohi'ona ka hi'ona o kēia pūnaewele pūnaewele, ka mea i "loa'a iā lākou" mai nā alagae.

'O ke'ano o ka pua

'O ke'ano ho'ohālā o nā mea kanu i kanu'ia, kahi i'ike'ia e ka pua, kahi kūpono loa. 'O kona mau'ao'ao nui ka pestle, kahi e waiho'ia ai ka hua, a me ka momona e loa'a ana i ka spermatozoa. Ke ho'ohui'ia lākou, ho'okumu'ia ka'ōpiopio o ka'ōpiopio.

Flower kapaia hoopokole ole a kaupalena i ka ulu ana o mutated pakele. Kaawale mai na stamens a me ka pistil, ka mea, he o peduncle a me ka perianth. 'O ka hapa mua he pālani elonui o ke kapuahi. I ke'ano, ua'ike pinepine'ia nā pikapuni kūkā a'ike'ole'ia. 'O nā lālā o kēia mau mea kanu he kulina, pua'a, plantain, clover. 'O nā'ano like'ole i kapa'ia he sedentary.

'O ka perianth kahi pūnaewele i ho'onohonoho'ia me kahi pahu carpels, a me kahi corolla. 'O ka hopena e hana'ia e nā momona, ka mea i ho'opili'ia nā lau. He nui nā mea kanu i kahi lola nui a'ālohilohi. 'O Roses, tulips, chrysanthemums, lilies - ua lō'ihi kēia mau pua nani i lilo i mea nani loa no ka ho'omaha ma'amau no kēia hō'ailona. 'O nā pua e ho'opuka i nā'ōpū. Wind-pollinated mea kanu i inconspicuous beaters a me ke ano nā'ōpuʻu.

'O ke kumu o ka ho'ohui lua

'O ke ka'ina hana o ka hawewe'ana o nā mea kaulike i mua o ka pollination. 'O kēia ke'ano o ka ho'ohuli'ana i ka pollen mai kahi'ē a'e o ka peni a ka wili o ka pistil. Hana'ia ia me ke kōkua'ana o ka makani, nā'ōpala, ka wai a me ke kanaka. I ka wā o ka ulu'ana,'elua mau sperm i komo. Ke ku'i me ke kōkua o ka germ tube i loko o ka'ōpiopio o ka pestle, kahi o lākou e mahalo me ka hua, a'o kekahi - me ka'ōpena pokapū. No laila, ua kapa'ia kēia hana i nā mea kanu ulu he'alua.

Nā'ano hua

No ka hopena o ka ho'okomo'ia o nā mea ho'okomo, ua ho'okumu'ia kekahi'ōpili pūnaewele i ho'ololi'ia. Aia kekahi hua i ho'opuni'ia e nā'ōpū. Kapa'ia lākou he pericarp. Hiki ke malo'o a'olu'olu. 'O nā lālā o ka hui mua he apple, drupe, berry and tykvina. Akā, he pi, he paila, he pahu, he hua, he hua a he namu nā hua malo'o.

'O ka hua a me ke'ano pilikino

'O ka hua e like me ke'ano o ka mea kanu o ka ulu ulu. 'O kēia hanana kūikawā mua i'ike'ia i loko o nā kumulā'au coniferous. I kēia wā, ua noho ka mea kanu i kahi kūlana ko'iko'i ma ka honua. 'O ka mea ma ka ho'ohālikelike'ana me ka hua,'oi aku ka holomua o ke'ano o ka hale. 'O kēia ke kumu nui o ka lako o nā mea'ai nā mea'ai a me nā pūpū o nā'ano'ano, ka mea hiki ke hilina'i pono i ka'ōpiopio mai ka makū a me nā'ano wela wela i hā'awi'ia e ka pericarp.

No laila, he pua ke'ano o ka hui o angiosperms, no ka ulu'ana o ka hua a me nā'ano'ano. Kēia hale i ke kaʻina hana o ka 'īnea i nā'ōlelo o nā mea kanu a me ka muli o hou holomua hiʻona o ka' ole o ka meaola.
