Tib neeg nrog rau tsiaj hom thiab nroj tsuag yog tsim los ntawm eukaryotic hlwb . Lub cev uas tsim nrog prokaryotic hlwb yog cov kab mob thiab archaea. Txawm li cas los xij hlwb tuav cov cwj pwm zoo sib xws. Piv txwv, eukaryotes thiab prokaryotes Ob leeg muaj plasma membrane, qhov no tiv thaiv cov ntaub ntawv extracellular nkag mus rau hauv cell.
Ib yam li ntawd, koj tuaj yeem nug, hom cell twg yog eukaryotic?
Eukaryotic cells yog cov hlwb uas muaj cov kab mob a nucleus . Ib tug raug eukaryotic cell yog qhia nyob rau hauv daim duab hauv qab no. Eukaryotic hlwb feem ntau loj dua li cov hlwb prokaryotic, thiab lawv muaj nyob hauv ntau cov kab mob. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes, thiab lawv txawv ntawm cov kab mob mus rau tib neeg.
Qhov thib ob, puas yog prokaryotes tsim tawm ntawm cov hlwb? Feem ntau cov kab mob ib leeg pom nyob rau hauv cov kab mob thiab Archaea domains yog hu ua prokaryotes . Cov kab mob no yog ua ntawm prokaryotic hlwb - qhov tsawg tshaj plaws, yooj yim tshaj plaws thiab qub tshaj plaws hlwb . Cov kab mob hauv Eukarya sau yog ua ntawm cov complex eukaryotic hlwb.
Tsis tas li ntawd, cov kab mob puas yog prokaryotic lossis eukaryotic?
Eukaryotic hlwb muaj cov organelles membrane-bound, nrog rau cov nucleus. Eukaryotes tuaj yeem ua ib leeg lossis ntau lub cell, xws li koj, kuv, nroj tsuag, fungi, thiab kab. Kab mob yog ib qho piv txwv ntawm prokaryotes . Prokaryotic hlwb tsis muaj cov nucleus los yog lwm yam membrane-bound organelle.
Dab tsi yog qhov txawv ntawm eukaryote thiab prokaryote hlwb?
Prokaryotes yog cov kab mob uas tsim los ntawm cell uas tsis muaj a cell nucleus los yog ib qho membrane-encased organelles. Eukaryotes yog cov kab mob uas tsim los ntawm cell uas muaj ib daim nyias nyias ntawm cov nucleus uas tuav cov khoom siv caj ces nrog rau cov kab mob sib txuas nrog cov organelles.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Dab tsi yog pom hauv eukaryotic hlwb tab sis tsis yog cov hlwb prokaryotic?
Eukaryotic hlwb muaj cov kab mob sib txuas ua ke, xws li cov nucleus, thaum cov hlwb prokaryotic tsis ua. Qhov sib txawv hauv cellular qauv ntawm prokaryotes thiab eukaryotes muaj xws li muaj mitochondria thiab chloroplasts, phab ntsa cell, thiab cov qauv ntawm chromosomal DNA
Puas yog dos hlwb prokaryotic lossis eukaryotic?
Ob leeg tib neeg thiab dos yog eukaryotes, cov kab mob uas muaj cov kab mob loj, cov hlwb nyuaj. Qhov no sib piv nrog cov me me, yooj yim hlwb ntawm prokaryotes zoo li cov kab mob. Qhov no suav nrog qhov loj, membrane-bound nucleus, chromosomes thiab Golgi apparatus, tag nrho pom nyob rau hauv tib neeg thiab dos
Dab tsi yog qhov txawv ntawm prokaryotic thiab eukaryotic hlwb hlwb?
Eukaryotic hlwb muaj cov kab mob sib txuas ua ke, nrog rau cov nucleus. Eukaryotes tuaj yeem ua ib leeg lossis ntau lub hlwb, xws li koj, kuv, nroj tsuag, fungi, thiab kab. Cov hlwb prokaryotic tsis muaj cov nucleus lossis lwm cov kab mob sib txuas ua ke
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
