Lub npe organelle los ntawm lub tswv yim hais tias cov qauv no yog ib feem ntawm cov hlwb, raws li lub cev yog rau lub cev, li no organelle , lub suffix -elle yog ib tug diminutive. Organelles tau txheeb xyuas los ntawm microscopy, thiab tseem tuaj yeem ua kom huv los ntawm cell fractionation. Muaj ntau hom organelles , tshwj xeeb tshaj yog nyob rau hauv eukaryotic hlwb.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog cov organelles?
Organelles yog cov qauv hauv ib lub cell uas ua haujlwm tshwj xeeb xws li tswj kev loj hlob ntawm tes thiab tsim lub zog. Piv txwv ntawm organelles pom nyob rau hauv eukaryotic hlwb muaj xws li: endoplasmic reticulum (zoo thiab ntxhib ER), Golgi complex, lysosomes, mitochondria, peroxisomes, thiab ribosomes.
Qhov thib ob, lub luag haujlwm ntawm organelles yog dab tsi? Core organelles muaj nyob rau hauv tag nrho cov eukaryotic hlwb. Lawv ua qhov tseem ceeb muaj nuj nqi uas tsim nyog rau kev ciaj sia ntawm cov hlwb - sau lub zog, ua cov proteins tshiab, tshem tawm cov khib nyiab thiab lwm yam. Core organelles suav nrog cov nucleus, mitochondria, endoplasmic reticulum thiab lwm yam.
Tib neeg kuj nug, vim li cas cov organelles hu ua cov kabmob me me?
Vim hais tias ib tug eukaryotic cell lub nucleus yog surrounded los ntawm ib daim nyias nyias, nws yog feem ntau hais tias muaj ib tug "tseem ceeb nucleus." Lo lus " organelle ” txhais tau tias “ lub cev me me ,”thiab, as xa hais , organelles muaj tshwj xeeb cellular zog, ib yam li cov lub cev ntawm koj lub cev muaj cov haujlwm tshwj xeeb.
Dab tsi yog 14 organelles?
Cov ntsiab lus hauv cov teeb no (14)
- Cell Membrane. Phospholipid txheej yog ib lub xovtooj ntawm sab nrauv "daim tawv nqaij."
- Cell phab ntsa. Ib qho nyuaj sab nrauv "phab ntsa" nyob ib puag ncig cov hlwb ntawm cov nroj tsuag, algae, thiab fungi.
- Nucleus.
- Ribosomes.
- Endoplasmic Reticulum.
- Mitochondria.
- Chloroplasts.
- Golgi complex.

Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Vim li cas tsev neeg yuav siv tus kws pab tswv yim caj ces lawv ua haujlwm li cas?
Cov kws pab tswv yim caj ces ua haujlwm ua ib feem ntawm pab pawg saib xyuas kev noj qab haus huv, muab cov ntaub ntawv thiab kev txhawb nqa rau cov tsev neeg uas cuam tshuam los ntawm lossis muaj kev pheej hmoo ntawm kev mob caj ces. Tshwj xeeb, cov kws pab tswv yim txog caj ces tuaj yeem pab cov tsev neeg kom nkag siab qhov tseem ceeb ntawm cov kab mob caj ces hauv cov ntsiab lus ntawm kab lis kev cai, tus kheej, thiab tsev neeg
