Nā'ōlelo - He aha ka keia? He aha nō i nāʻaoʻao, a reproductive nā loko?

Kekahi o ka loa eiiieaena, pohihihi a kupaianaha keʻano o ka hanaʻana i loko o maoli - ia mea multiplication. He mea nui, a no ka mea, Kākoʻo ola loa a pau meaola e noho ana ma ka honua nei. E hoʻomaka i kālailai i oi au mamuli mea ia mea. Nā'ōlelo - o ka hiki ana o nā mea ola, e hanau ana i na meaola lakou iho. Me keia hiki, i ola 'elele ano hiki i noho ma ka honua.

? aneii Nā Papahana

Ano, e noonoo i ke ano o ka'ōlelo, ka mea i wale elua. Ka mea, OAOOUIEeE me ka nui loa mai o kekahi i kekahi, akā, i kekahi manawa i ka loa mailuilu haalele liilii mea, e hiki ike i ka mea like.

asexual nā'ōlelo

ua kapaia asexual nā'ōlelo o ka meaola e like me protozoa, fungi, koʻohune, coelenterates, ka līoho, ka huahuakai, tunicates, bryozoans a me vascular mea kanu.

Ka simplest ano o ke kumu kāki i hiki e wahi ana i nā mea hoʻomaʻi. Ma kēia kaʻina hana, hula ka nui kūlana nukelea nāʻakika, e like me ka hiki ana o na nā lātoma i ka pakiko-a pāpālua hoʻi. Kekahi ua nānā 'ana i hydrogen makaukau na kaula paa fragile i waena o nucleotides.

Aia i nāʻaoʻao o ka asexual nā'ōlelo o ka meaola - vegetative a me ka spore ho okumu pololei.

Mua, noonoo i ka vegetative. Oia nā'ōlelo - o ka hooulu ana o ka hou meaola o ka hapa, a ua hookaawale ae mai ka makuahine. A like iaoia mea he ulu i loko o ka heluna kanaka o unicellular a me ka multicellular meaola, akā, e hoike mai ai ia ia iho ma naʻano likeʻole.

I ka vegetative propagation mahele o ko lākou mau kino hoʻomaka multicellular holoholona i like, alaila, mai ka mea, he mea he ola meaola. Like me, ka heluna kākoʻo flatworms nemerteans, ka huahuakai, hooponopono pookela, a ua nui no hoi na mea kolo. Akā, he mea e like me ka mea i polyembryony holoholona. I loko o kēia kaʻina hana, ka embryo i kekahi mau manawa ua maheleia i māhele i ka mea, a laila hoʻomohala i loko o ke kaʻawale kino. Oia ka papa o ke kumu kāki i mālama i loko o armadillos. It E e kaulana i ka mea wale nō paʻi nā kiʻie hōʻikeʻike.

Vegetative nā'ōlelo o ka unicellular loaʻa paha kekahi mau ano - i opuu ae, a me ka mahele o kekahi mau māhele.

Mau mahele ua kapaia schizogony, ma keia hihia, no ka māheleʻia kāna mau 'ōlelo, a laila, e disconnected cytoplasm ma ke kaʻawale.

Ke kaʻina Ua puni hoʻi mahele mitotic fission mapuna kahi warping ia lŘlŘ hou cytoplasm.

Ano, ke hele mai i ka asexual i opuu ae. Oia nā'ōlelo - o ka muli o kūikawā keena a spores i loaʻa kāna mau 'ōlelo. Ka mea, i ka mānoanoa ili a me ka lōʻihi lawa ke ola i loko o ka loa adverse o ana. He hoi he ia nui ma wā e hiki mai ko lakou noho. Kēiaʻano o ka'ōlelo ano o mosses, fungi, ka līoho, koʻohune a me Fern. Aia ka he manawa kūpono no ke kahua o zoospores o kekahi uliuli līoho keena.

Animal nā'ōlelo sporulation hiki ke loaʻa i loko o ka malaria plasmodium a me Sporozoa.

He nui meaola ke hui pu iho asexual nā'ōlelo i ka moe.

syngenesis

Moe nā'ōlelo - he oi eiiieaena kaʻina, a no ka piha pele pono mau kanaka, o ke kane a me ka wahine. I ka holo ana o kona aaiaoeʻikepili ua panai aku ma nā gametes (keia germ aeee). Kēia kaʻina ua kapaia gametogenesis.

Ma keia hihia pū, loaʻa nō kekahi mau waeʻano: hookahi-aa? Meaola hoʻokuʻi pū a me ka germ keena e like me sperm a me ka hua. Ma kēia kaʻina hana, ma laila nō ka zygote, mai a kekahi hou kino ua hana. Once ka mea, hiki waiwai nui, hoʻomaka e pāʻani ai ma luna o lākou iho gametes.

He nui na ano o ka moe nā'ōlelo, a pū keʻano o ke keena, a me ka reproductive nā loko.

Ano a me ka ano o ka? Aneii

Oe Pono e noonoo i hou aku au mamuli kēlā me kēia kaʻina kaawale, no ka mea, a pau i kekahi mau kumu a me ka pele.

About gametogenesis olelo mua, no laila mākou e ole 'oe.

Isogamy a anisogamy

Ma kēia mauʻano o ke keena lawe mau wahi, akā, isogamy pili ia i ka ia aeea o ka 'ole, akā, e iho ana mai o kekahi mau mākua. Anisogamy kükulu i kekahi mau germ keena - a me ka microgamete macrogametes, a ĸokoĸa ana nä pane ma ka nui.

Hua a me ka sperm

No laila, kapa kāne a me ka wahine germ keena. Ka mea i hanaʻia i loko o ka wahine pili kanaka.

Ka hua manu ninoieo o Halide chromosomes, a hiki ole kaʻana like i kou iho.

Sperm aeee i iki uuku wahine keena. Ka mea, i kekahi mea kupaianaha 'ole, a ua hoakaka ia me kaʻeleu neʻeʻana. Ke alo aku o kekahi mau nā'ūhū i loko o ka axoplasm e hoʻolako no cleavage o ka ovum anal paia a me ka hou fertilization. Kēlā me kēia gamete he i kekahi hapa o ka aaiaoe 'ike o nā mākua, a hele ia i ka wā e hiki mai keiki kakou nana.

parthenogenesis ponoʻole

Oia nā'ōlelo - ia mea,ʻaʻole he typical moe kaʻina. Ua hiki ke hoʻomaopopo i ka loli typical a me ka atypical nā'ōlelo. Ka wahine e hoʻomōhala ana i na hua fertilized, a me kane - mai unfertilized. Pela ka mea, he mahuahua nalo meli ia heluna.

Aia nō i nāʻano likeʻole o ka parthenogenesis,ʻo ia ka ikaika a me ka cyclical. Ma ka hihia mua, ka mamo hoʻomōhala mai hua paha, mea e malama i ka fertilization. Kēia hiki ana i loko o ia kanaka, na makua o kona mau hui no nā'ōlelo mea,ʻaʻole hiki i ka halawai.

Ma ka hihia o cyclic parthenogenesis pāʻani ka nui kūlana? Aneie ana. Ma lalo o kona keiki, he mea ka alternation o ka typical? Aneii me ka parthenogenesis.

A pau ka 'ike i hoʻolako mea wale nō i ka hapa uuku wale no o ke ano o ka loa kupaianaha a me ka pohihihi kaʻina hana ma luna o ka honua -? Aneii. Mahalo iā ia, ma laila i kēia manawa a pau e ola ana meaola a me nā mea kanu. Inā wale no ka manawa e manaʻo e pili ana pehea kēia kaʻina a pau pono, naʻauao, a thoughtfully hooponopono, e mea hiki ke hoʻomaopopo i ka mana o nā mea a pau ano. Ma ka nui o nā lātoma a me chromosomes neia manawa, ua kahaha ko oukou naau i na mea i ka na kanaka paakiki i maopopo.
