Amaseli ayiyunithi eyisisekelo yokuphila, futhi angahlukaniswa ngezinhlobo ezimbili: ama-prokaryotes nama-eukaryote. Kulesi sihloko, sizohlola umehluko phakathi kwalezi zinhlobo ezimbili zamaseli.
I-1. Isingeniso
Amaseli atholakala kuzo zonke izinto eziphilayo futhi enze imisebenzi ebalulekile ephilayo. Nakuba wonke amangqamuzana enezici ezifanayo, kunomehluko omkhulu phakathi kwamaseli e-prokaryotic ne-eukaryotic.
2. Iyini iseli ye-prokaryotic?
Amaseli e-Prokaryotic alula futhi akudala kakhulu. Zikhona ezintweni ezinengqamuzana elilodwa, njengebhaktheriya kanye ne-archaea. Isici esiyinhloko salawa maseli ukuthi awanayo i-nucleus echaziwe noma ama-membranous organelles. Esikhundleni salokho, izinto zofuzo zihlakazeka ku-cytoplasm.
3. Liyini iseli le-eukaryotic?
Amaseli e-Eukaryotic ayinkimbinkimbi kakhulu kunamaseli e-prokaryotic futhi atholakala ezintweni eziphilayo ezinamangqamuzana amaningi, njengezitshalo, izilwane kanye nesikhunta. Isici esiyinhloko salawa maseli ukuthi ane-nucleus echaziwe, ezungezwe ulwelwesi lwenuzi, nama-organelle ahlukahlukene e-membranous enza imisebenzi ethile.
4. Umehluko phakathi kwamaseli e-prokaryotic ne-eukaryotic
Umehluko omkhulu phakathi kwamaseli e-prokaryotic kanye ne-eukaryotic yilezi:
4.1. isakhiwo seseli
Emaseli e-prokaryotic, izinto zofuzo zihlakazeka ku-cytoplasm, kuyilapho kumaseli e-eukaryotic, kuqukethwe ngaphakathi kwe-nucleus. Ukwengeza, amaseli e-eukaryotic anama-membranous organelles, njenge-endoplasmic reticulum, i-Golgi apparatus, ne-mitochondria, engatholakali kuma-prokaryotes.
4.2. Usayizi nokuma
Amaseli e-Prokaryotic mancane futhi alula kunamaseli e-eukaryotic, futhi anomumo olula futhi ojwayelekile. Ngakolunye uhlangothi, amangqamuzana e-eukaryotic makhulu futhi ayinkimbinkimbi, futhi angaba nezimo ezihlukahlukene nezikhethekile.
4.3. Ukuhlukaniswa okusebenzayo
Amangqamuzana e-Eukaryotic anama-organelles akhethekile enza imisebenzi ethile, njengokwakheka kwamaprotheni, ukukhiqizwa kwamandla, nokukhipha imfucuza. Ngakolunye uhlangothi, kumaseli e-prokaryotic, yonke imisebenzi yenziwa ku-cytoplasm.
4.4. Ukuzala kabusha
Amaseli e-Prokaryotic akhiqiza ngokuhlukaniswa kwamaseli okulula, kuyilapho amangqamuzana e-eukaryotic angakwazi ukuzala kokubili ukuhlukaniswa kwamaseli okulula kanye ne-meiosis.
I-5. Iziphetho
Kafushane, amaseli e-prokaryotic alula futhi akudala kakhulu kunamaseli e-eukaryotic, awanayo i-nucleus echaziwe kanye nama-membranous organelles, futhi akhiqiza ngokuhlukaniswa kwamaseli okulula. Ngakolunye uhlangothi, amangqamuzana e-eukaryotic makhulu futhi ayinkimbinkimbi kakhudlwana, anenucleus echaziwe, ama-membranous organelle ahlukahlukene akhethekile, futhi angazalana ngokuhlukana kwamaseli okulula nange-meiosis.

Imibuzo Evame Ukubuzwa
Uyafuna ukwazi okwengeziwe ngomehluko phakathi kweseli ye-prokaryotic ne-eukaryotic? Lapha sethula uhlu lwemibuzo evame ukubuzwa ukucacisa konke ukungabaza kwakho.
1. Yimuphi umehluko obalulekile phakathi kweseli le-prokaryotic ne-eukaryotic?
Umehluko omkhulu ukuba khona noma ukungabi khona kwe-nucleus yeseli echaziwe. Iseli le-eukaryotic linenucleus echazwe ngokucacile, kuyilapho iseli le-prokaryotic lingenayo. Omunye umehluko uhlanganisa ukuba khona kwama-organelles eselula kumaseli e-eukaryotic kanye nesakhiwo sodonga lwamaseli.
2. Isakhiwo seseli ye-prokaryotic sibukeka kanjani?
Amaseli e-Prokaryotic ngokuvamile mancane futhi alula kunamaseli e-eukaryotic. Isakhiwo sayo esiyisisekelo sihlanganisa ulwelwesi lwe-plasma, i-cytoplasm, nezinto zofuzo ezihlakazeke ngaphakathi kwe-cytoplasm endaweni ebizwa ngokuthi i-nucleoid. Ngaphezu kwalokho, banezindonga zamaseli eziqinile ngaphandle.
3. Yiziphi izinhlobo zezinto eziphilayo ezinamaseli e-prokaryotic?
Amaseli e-Prokaryotic atholakala ezintweni ezineseli elilodwa njengebhaktheriya ne-archaea. Lezi zinambuzane zihluke kakhulu futhi zitholakala kuzo zonke izindawo emhlabeni.
4. Sibukeka kanjani isakhiwo sengqamuzana le-eukaryotic?
Amaseli e-Eukaryotic anesakhiwo esiyinkimbinkimbi kunamaseli e-prokaryotic. Ngaphezu kwe-nucleus echaziwe, banama-organelle amaselula ahlukahlukene, njenge-mitochondria, i-ribosomes, i-endoplasmic reticulum, ne-Golgi apparatus.
5. Yiziphi izinhlobo zezinto eziphilayo ezinamaseli e-eukaryotic?
Amaseli e-Eukaryotic atholakala ezintweni eziphilayo ezinamangqamuzana amaningi njengezitshalo, izilwane, isikhunta, nabanye abadwebi. Lezi zinambuzane zinobunzima obukhulu kanye nokwehlukahlukana kunezinto eziphilayo ezinamaseli e-prokaryotic.
