Zoo li lub cell prokaryotic, a eukaryotic tshuaj cell muaj ib plasma daim nyias nyias cytoplasm, thiab ribosomes. Txawm li cas los xij, tsis zoo li cov cell prokaryotic, eukaryotic tshuaj hlwb muaj :ib daim nyias nyias - khi nucleus. ntau heev daim nyias nyias - khi organelles (xws li endoplasmic reticulum, Golgi apparatus, chloroplasts, thiab mitochondria)
Ib yam li ntawd ib tug yuav nug, puas yog prokaryotes puas muaj daim nyias nyias organelles?
Eukaryotic hlwb muaj daim nyias nyias - khi organelles , suav nrog lub nucleus. Prokaryotic hlwb ua tsis muaj nucleus lossis lwm yam daim nyias nyias - khi organelle . Prokaryotes suav nrog ob pawg: kab mob thiab lwm pab pawg hu ua archaea.
Tsis tas li ntawd, cov organelles twg yog daim nyias nyias thiab uas tsis yog? Non-membrane bound organelles yog cov khoom siv ntau dua uas tsis muaj kua dej puv, yog li lawv tsis xav tau daim nyias nyias. Piv txwv ntawm non-membrane bound organelles yog cov ribosomes , cell phab ntsa, thiab cytoskeleton.
Kuj Paub, vim li cas eukaryotes muaj daim nyias nyias organelles?
Membrane - Eukaryotic organelles raug khi cov hlwb muaj cov khoom sib sau ua ke ntawm cov protein uas ua haujlwm ua ib chav hu ua organelles . Qhov thib ob, cov hlwb tuaj yeem txwv cov proteins uas tsim kev puas tsuaj thiab cov molecules hauv daim nyias nyias - khi organelles , tiv thaiv tus so ntawm cov hlwb los ntawm lawv cov teebmeem.
Cov tsiaj cell puas muaj daim nyias nyias khi organelles?
Tsiaj hlwb yog eukaryotic tshuaj hlwb uas muaj ob a daim nyias nyias - khi nucleus thiab lwm yam daim nyias nyias - khi organelles . Cov no organelles ua cov haujlwm tshwj xeeb uas yog xav tau rau lub cev ua haujlwm ntawm lub cell . Nroj tsuag thiab tsiaj hlwb yog zoo ib yam li lawv yog ob qho tib si eukaryotic thiab muaj zoo sib xws hom organelles.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Cov kab mob puas kis cov kab mob eukaryotic?
Ib lub cell uas muaj kab mob ua rau cov kab mob kis tau ntau dua thiab cov khoom siv caj ces es tsis yog nws cov khoom qub. Qee cov kab mob yuav nyob twj ywm hauv cov tswv tsev rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv cov tswv tsev (ib theem hu ua lysogenic theem). Cov kab mob ua rau muaj ntau yam kab mob hauv eukaryotes
Cov kab mob twg muaj cov kab mob eukaryotic?
Cov kab mob thiab Archaea tsuas yog prokaryotes. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes. Tsiaj txhu, nroj tsuag, fungi, thiab protists yog eukaryotes. Tag nrho cov kab mob multicellular yog eukaryotes
Puas yog cov kab mob unicellular kab mob?
Tus Kab Mob Qhov Twg Zoo? Cov kab mob tsis raug cais raws li cov hlwb thiab yog li tsis yog unicellular lossis multicellular kab mob. Cov kab mob muaj cov genomeshat muaj xws li DNA lossis RNA, thiab muaj cov piv txwv ntawm cov kab mob uas yog ob leeg-stranded orsingle-stranded
Cov kab mob puas yog ib hom kab mob ntawm tes?
Teb thiab piav qhia: Cov kab mob no tsis suav tias yog cov cell nyob thiab yog li ntawd tsis yog ib leeg-celled lossis ntau-celled. Lawv tsuas yog suav hais tias yog cov plhaub protein
