Ib lub cell eukaryotic yog ib lub xovtooj ntawm tes uas muaj cov membrane-txheej nucleus thiab lwm yam membrane-bound compartments los yog hnab, hu ua organelles , uas muaj cov haujlwm tshwj xeeb. Lo lus eukaryotic txhais tau hais tias "tseeb kernel" los yog "tseeb nucleus," hais txog qhov muaj cov membrane-bound nucleus hauv cov hlwb.

Ib yam li ntawd, koj tuaj yeem nug, hom cell twg tsis muaj daim nyias nyias nyias?

Teb thiab piav qhia: Ib lub cell prokaryotic yog hom uas tsis muaj cov membrane-bound nucleus. Prokaryotic hlwb yog qhov yooj yim thiab qub, tsis muaj tseeb organelles.

Tom qab, lo lus nug yog, puas yog nucleus npog los ntawm daim nyias nyias? Nucleus yog npog los ntawm a daim nyias nyias hu ua lub hnab ntawv nuclear. Kev piav qhia: Nucleus yog lub cell organelle uas nqa cov khoom siv caj ces ntawm lub cev. Nws yog npog los ntawm a daim nyias nyias hu ua nuclear lub hnab ntawv uas muaj ob txheej ntawm lipids uas yog embedded nyob rau hauv ib tug nyias txheej ntawm kua.

Yog li ntawd, puas yog lub cell prokaryotic puas muaj cov membrane khi nucleus?

Prokaryotes tsis muaj kev koom tes nucleus thiab lwm yam daim nyias nyias - khi organelles. Prokaryotic DNA yog pom nyob rau hauv ib feem ntawm lub hauv paus cell hu ua nucleoid.

Muaj pes tsawg daim nyias nyias nyob hauv ib lub cell?

Cov lipid molecules ntawm ob lub bilayers rearrange lawv tus kheej thiab ob daim nyias nyias yog, yog li, fused. Ib txoj kev yog tsim nyob rau hauv lub fused daim nyias nyias thiab vesicles tawm nws cov ntsiab lus sab nraum lub cell.
