Contain DNR - prokaryote thiab eukaryote. DNR yog pom raws li ib tug ntev irregularly zoo li tus molecule - prokaryote. DNR tau ntim nrog cov protein tshwj xeeb hu ua chromosomes - eukaryote.
Puas eukaryotes puas muaj Pili?
Eukaryotic cells tsis muaj lub hnab ntawv xovtooj, vim tias cov tsiaj txhu thiab cov nroj tsuag tsis muaj pili thiab cov tshuaj ntsiav thiab cov cell cog tsis muaj phab ntsa ntawm tes. Prokaryotic hlwb tsis muaj cov organelles feem ntau, piv txwv li mitochondrion, chloroplasts, thiab cilia. … Qee qhov piv txwv ntawm prokaryotes yog cov kab mob thiab archae.
YPuas yog endoplasmic reticulum prokaryotic lossis eukaryotic?
Endoplasmic reticulum, microtubules, thiab Golgi apparatus yog tshwj xeeb rau eukaryotic hlwb, thiab yuav tsis pom nyob rau hauv prokaryotes.
YPuas prokaryotes puas muaj Nucleoids?
Feem ntau cov prokaryotes nqa ib qho me me ntawm cov khoom siv caj ces hauv daim ntawv ntawm ib qho molecule, lossis chromosome, ntawm cov DNA ncig. Lub DNA hauv prokaryotes muaj nyob hauv thaj chaw nruab nrab ntawm lub xovtoojhu ua nucleoid, uas tsis nyob ib puag ncig los ntawm cov membrane nuclear.
eukaryotic hlwb muaj dab tsi?
Eukaryote, txhua lub cell lossis kab mob uas muaj a kom meej meej cov nucleus. Lub eukaryotic cell muaj ib daim nyias nyias uas nyob ib puag ncig lub nucleus, uas cov chromosomes uas tau hais tseg zoo (lub cev uas muaj cov khoom siv los ntawm noob neej) nyob.

Lub xovtooj twg muaj cov plasma membrane?
Ob leeg prokaryotic thiab eukaryotic hlwbmuaj cov plasma membrane, ob txheej ntawm lipids uas cais cov cell sab hauv los ntawm ib puag ncig sab nraud. Ob txheej txheej no muaj cov lipids tshwj xeeb hu ua phospholipids. Pob cog cov hlwb puas muaj plasma membrane?
Tus xov tooj hu xovtooj xovtooj yog dab tsi?
Koj tuaj yeem ncav cuag Lub Chaw Haujlwm Ua Haujlwm ntawm (202) 551-4790. xov tooj hu xovtooj yog dab tsi? Ib tus xov tooj hu xovtooj cua (lossis xov xwm xov xwm) yog ib qho kev pabcuam uas pab cov neeg ua haujlwm thiab lwm tus tshaj tawm txog kev ua phem thiab tsis raug cai lossis tsis ncaj ncees hauv chaw ua haujlwm.
Lub xovtooj twg yog triploid hauv cov nroj tsuag angiosperm?
Hauv angiosperms, zygote yog diploid thaum lub primary endosperm cell yog triploid. Dab tsi yog triploid nyob rau hauv ib txwm angiosperm? Kwv yees li 70% ntawm hom angiosperm muaj cov hlwb endosperm uas yog polyploid. Cov no feem ntau yog triploid (muaj peb pawg chromosomes), tab sis tuaj yeem sib txawv ntawm diploid (2n) txog 15n.
Thaum twg thylakoid nyob hauv ib lub xovtooj?
Thylakoids yog cov txheej txheem membrane-bound ntawm qhov uas lub teeb nyob ntawm kev cuam tshuam lub teeb nyob ntawm qhov kev cuam tshuam Cov tshuaj tiv thaiv no siv photolysis, lossis siv lub teeb lub zog los faib cov dej molecules thiab tsim cov pa oxygen.
Qhov twg ntawm lub xovtooj stained xiav tsaus?
Thaum ib tee ntawm methylene xiav tau qhia, lub nucleus yog stained, uas ua rau nws sawv thiab pom meej nyob rau hauv lub microscope. Txawm hais tias tag nrho cov xov tooj ntawm tes pom lub teeb xiav xim, lub nucleus ntawm qhov nruab nrab ntawm lub xovtoojyog qhov tsaus dua, uas tso cai rau nws txheeb xyuas.
