Eyona engundoqo amalungiselelo theory iseli - umanyano zonke postulates zobomi

Amalungiselelo eziphambili ithiyori iseli sisiseko siqonde imvelaphi komthetho kwaye ubukho izinto eziphilayo, eliquka iiyunithi nezakhiwo. Oku gabalala lokuziswa eziphilayo ukuba ubomi ikhona kuphela ebuhlanti, kwakunye nenyaniso yokuba wonke "iseli ophilileyo" kuba sonke isimiso ezinokuba khona ngokuzimeleyo.

Amalungiselelo ephambili e-worldwork theory iseli ziye ziqulunqwe M. Schleiden kunye T. Schwann eya kuthi yongezwe R. Virchow. Phambi kokuba wenze izigqibo kwaye kukuqulunqa postulates yalo mbono, iingcali babesebenza imisebenzi ezininzi ababengaphambi kwakhe. Ngokomzekelo, ngowe-1665 , uRobert Hooke kuqala ndabona ukuyilwa tube, ebizwa ngokuba "iiseli". Emva koko wachaza ukuba isakhiwo zeselula ze izityalo ezininzi. Kamva A. Leeuwenhoek wachaza kwiseli enye. Ekhulwini XIX. ukuphucula uyilo neemicroscope kukhokelela ekubeni banzi ingqikelelo ubume eziphilayo, wazisa ingqiqo eziphilayo. T. Schwann uqhuba Uhlalutyo lokuthelekisa iyunithi incinane kwisakhiwo enezityalo nezilwanyana, yaye Schleiden ethi "Izixhobo kwi phytogenesis".

Eyona engundoqo Amalungiselelo e-worldwork theory yeseli, eyenziwe yi Schleiden and Schwann:

1. Zonke izityalo nezilwanyana iqanjwa kweeyunithi nezakhiwo.
2. Ukukhula kunye nophuhliso zezityalo nezilwanyana eziphilayo zenzeka ngenxa ukuvela "iiseli aphilayo" ezintsha.

Esi sakhiwo iyunithi incinane umzimba ephilileyo - iseti kubo.

ke R.Virhov wongezelela ingongoma ebalulekileyo kakhulu ukuba zonke iyunithi noshowo livela ngohlobo lwazo. Lo msebenzi yahlelwa yaye kushwankathelwe amaxesha amaninzi. Ngoku ke eziphambili izibonelelo theory mihla yeseli imi ngolu hlobo lulandelayo:

1. Iseli iyunithi aphantsi wokuphila.
2. Iyunithi incinane noshowo zonke izinto eziphilayo ukwakhiwa homologous lweenkqubo ubomi metabolic.
3. Bazale division cell umzali.
4. Zonke iiyunithi eziphilayo kwezobom omnye umgaqo, oko kukuthi, ke totipotent.
5. Xa eziphilayo multicellular iiyunithi zokuhlala oqhagamshelwano phakathi zimanyene incinane ngokunxulumene nemisebenzi ukusebenza, kanjalo bakha isakhiwo olunzima kakhulu (tissue, organ kunye omzimba).
6. Ngamnye "iseli ophilileyo" i inkqubo evulekileyo, elinako self-unokuyilawula inkqubo uphuculo, ukudlala, nokugcina homeostasis.

Kwiminyaka embalwa edlulileyo (emva eziliqela izinto ezifunyaniswe zizazinzulu) ukwandisa le ngcamango, ukudibanisa ulwazi olutsha. Nangona kunjalo, akukho systematized ngokupheleleyo, ngoko postulates ezinye zitolikwe kakhulu ezinemvume. Cinga izibonelelo ezongezelelweyo theory seli iqhelekileyo:

1. Iiyunithi incinane noshowo eziphilayo pre-nuclear kwakunye yenyukliya akukho ngokupheleleyo yakheke kunye nesakhiwo efanayo omnye komnye.
2. Ukuqhubeka ukudluliselwa kolwazi yemfuza ukwasebenza organelles ezithile (chloroplasts, mitochondria, zofuzo, genes) "iseli ophilileyo".
3. unit eziziziqalelo ophilileyo, nangona totipotent, nangona kunjalo, ukuba umsebenzi yofuzo zahlukile. Le nto ikhokelela iyantlukwano yabo.
4. Multicellular bamele entsonkothileyo inkqubo yenu leyo ikhutshwa phandle imichiza zinto, humoral kunye zobuchopho ummiselo.

Ngenxa yoko, izibonelelo ezingundoqo kwethiyori Iseli elamkeleke jikelele gabalala eziphilayo, nto leyo ebonisa umanyano ngesakhiwo umgaqo ubukho kunye nophuhliso zonke izidalwa eziphilayo ukuba isakhiwo zeselula.
