Aitanga i roto i teitei me raro momo o otaota

Whakatö āhuatanga o rauropi katoa. E whakarato ana tēnei i te kaha ki te whakaputa uri i te tauatanga, me te tonu o te ora. I roto i ngā e whai he āhua pūtau o te hanganga, e hāngai ana te tupuranga i runga i te wehenga.

momo whakarōpū rerekē o te uri kua whakaarohia e te pūtaiao rerekē. Ko te tikanga whakaaro e toru ngā momo o te uri: vegetative, fakasekisualé, me te paratau.

I roto i te take whakamutunga, kawea te whanaketanga o te kaiao te roto i te pūtau kotahi e kore e rerekëtanga moepuku. Hoki uri vegetative āhuatanga e te whanaketanga o te kaiao multicellular i iroriki, ētahi wā uaua ki te rerekëtanga.

Fakasekisualé uri o ngā tipu tīmata ki te hanganga o ngā pūtau iroriki (tohuhema). heke reproduction takekore te ki te hanumi, o tohuhema i te whakatō kākano. huaina ana tēnei tukanga ko te kikiritanga me whakawhiti mōhiohio iranga i ngā mātua ki te uri.

Tohuhema e hanga e i roto i te kikokiko - gametangia. tipu māngai, e kua āhuatanga e te kikiritanga, i roto i to ratou huringa ora, whāiti pūira.

e kore te mea ulungāanga hoki uri ā-tōkai pükohu puru-matomato, huakita. Ehara i kitea he ara o te uri me te maha o te harore.

He rerekē ngā momo o te aitanga i roto i nga momo o raro o otaota. Hei tauira, ka taea e etahi tukanga reproduction pükohu matomato puta i waho i te hanganga o tohuhema. I roto i tenei take, te kaiao e rua wiki-tahi.

Ko te hanumi, o tohuhema, e whai flagella, ka karanga isogamy. He angamaheni o pükohu maha uri Fakasekisualé.

pükohu rauropi pūtau (Chlamydomonas etahi, hei tauira) ki etahi whānuitanga, ratou tahuri ki te whekau fakasekisualé hanga tohuhema. I roto i te māngai multicellular gametangia e etahi kahore e e rerekē i ētahi atu pūtau gametangia ranei i hanga ki te rerekētanga morphological (hei tauira, ektokarpusa).

He tokomaha hoki pükohu isogamous geterotallizm āhuatanga (ira, me te whaiaroaro wehenga fakasekisualé). Ko te kupu i reira ko te hononga o tohuhema physiologically rerekē.

Hoki etahi pükohu e āhuatanga e te conjugation: i reira ko "waipuke" he pūtau protoplast ki tetahi.

Ko te hanumi, o tohuhema ki rerekē te rahi o flagella, ka karanga heterogamy. Pūhui bezzhgutikovoy gamete wahine (oocyte) me he flagella (te tikanga) tane iti (parāoa) he oogamy. He angamaheni o maha whero, parauri, diatoms, pükohu matomato, me te tahi mau harore raro uri tōkai.

Kikiritanga i roto i gologamnyh, kawea heterogamic, tipu isogamous me tino oogamnyh te roto i roto i te wai. He maha o te tukanga hanumi tipu oogamnyh puta i roto i te oogonia (gametangia wahine). E mātātoa neke ratou parāoa tukua ki te wai. puta te mahi ki te kia tika ki chemotaxis. Ko te kupu spermatsii pükohu whero (pükohu whero) e oho e te rere te wai - pē.

He oogamnymi tipu Higher. Heoi, e te kikiritanga wahi i ratou i roto i ara rerekē. Hoki tipu teitei He gametangia multicellular angamaheni - archegonium (wahine), me te antheridia (tane). Ko te kahu i waho o ngā pūtau o te whekau taihemahema he horomata. I roto i te archegonia i hanga ovum kotahi i roto i antheridia spermatozoa e hanga e te nuinga o roto i te moni tiketike.

kawea kaponga aitanga me talingelingá i roto i roto i te wai. mai ngā pūtau parāoa i antheridium ka neke ki te archegonium. I roto i te tahuri, rite ki te he wairakau archegonium kukume parāoa ngoto hūpē te huna hoki i te tihi. Haere ki roto ki te hūpē, te parāoa piri ki te hua manu, engari hanumi reira ki tetahi.
