Nws yog tsim los ntawm dej, ntsev, thiab cov proteins. Hauv eukaryotic hlwb , cov cytoplasm suav nrog tag nrho cov khoom nyob rau hauv cell thiab sab nraum lub nucleus. Tag nrho cov organelles nyob rau hauv eukaryotic hlwb , xws li cov nucleus, endoplasmic reticulum, thiab mitochondria, yog nyob rau hauv lub cytoplasm.
Ib yam li ntawd, tib neeg nug, puas yog cytoplasm hauv cov nroj tsuag lossis tsiaj hlwb?
Tsiaj hlwb thiab cov hlwb cog sib koom ua ke ntawm ib qho nucleus cytoplasm, mitochondria thiab cell membrane. Cov nroj tsuag muaj peb yam ntxiv, lub vacuole, chloroplast thiab phab ntsa ntawm tes.
Ib yam li ntawd, cytoplasm yog dab tsi? Cytoplasm yog cov kua dej uas sau cov hlwb thiab ua haujlwm rau ntau yam haujlwm tseem ceeb. Cytoplasm tuav cov khoom sab hauv ntawm cov hlwb nyob rau hauv qhov chaw thiab tiv thaiv lawv los ntawm kev puas tsuaj. Cytoplasm khaws cov molecules siv rau cov txheej txheem ntawm tes, nrog rau muaj ntau yam ntawm cov txheej txheem no hauv lub xov tooj ntawm tes.
Tom qab ntawd, tag nrho cov cell puas muaj cytoplasm?
Txhua lub hlwb muaj plasma daim nyias nyias, ribosomes, cytoplasm , thiab DNA. Ribosomes yog cov non-membrane bound organelles qhov twg cov proteins raug tsim, txheej txheem hu ua protein synthesis. Cov cytoplasm yog tag nrho cov ntsiab lus ntawm cell hauv cov cell membrane, tsis suav nrog cov nucleus.
Dab tsi yog cytoplasm nyob rau hauv cov nroj tsuag cell?
-plăz'?m] Cov khoom siv jellylike uas ua rau ntau yam cell hauv cov cell membrane , thiab, hauv eukaryotic hlwb , puag ncig lub nucleus. Cov organelles ntawm eukaryotic hlwb , xws li mitochondria, endoplasmic reticulum, thiab (hauv ntsuab nroj tsuag ) chloroplasts, muaj nyob hauv cytoplasm.

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
Lub npe ntawm cov enzyme uas kuaj pom hauv qhov kev kuaj pom zoo catalase yog dab tsi?
Catalase Test- Ntsiab Cai, Siv, Txheej Txheem, Txhais Lus Txhais nrog ceev faj. Qhov kev sim no qhia pom tias muaj catalase, ib qho enzyme uas ua rau cov pa tawm ntawm cov pa oxygen los ntawm hydrogen peroxide (H2O2)
Dab tsi ntawm cov hauv qab no muaj nyob rau hauv cov tsiaj hlwb tab sis tsis yog cov nroj tsuag?
Mitochondria, Cell Phab ntsa, Cell membrane, Chloroplast, Cytoplasm, Vacuole. Lub cell phab ntsa, chloroplasts thiab vacuole muaj nyob rau hauv cov nroj tsuag cell es tsis yog tsiaj hlwb
Cov tshuaj dab tsi tuaj yeem txav mus rau hauv lossis tawm ntawm cov hlwb los ntawm kev nthuav tawm?
Dej, carbon dioxide, thiab oxygen yog ib qho ntawm ob peb yam yooj yim molecules uas muaj peev xwm hla lub cell membrane los ntawm diffusion (los yog ib hom diffusion hu ua osmosis). Diffusion yog ib txoj hauv kev ntawm kev txav ntawm cov khoom nyob rau hauv cov hlwb, nrog rau txoj kev rau cov me me molecules tseem ceeb hla lub cell membrane
Leej twg biologist tau qhia lub sij hawm prokaryote nyob rau hauv 1937 kom paub qhov txawv hlwb uas tsis muaj nucleus los ntawm nucleated hlwb ntawm cov nroj tsuag thiab tsiaj txhu?
Prokaryote / Eukaryote nomenclature tau thov los ntawm Chatton hauv 1937 los faib cov kab mob nyob rau hauv ob pawg loj: prokaryotes (cov kab mob) thiab eukaryotes (cov kab mob uas muaj cov cell nucleated). Tau txais los ntawm Stanier thiab van Neil qhov kev faib tawm no tau lees paub thoob ntiaj teb los ntawm cov kws tshawb fawb txog biologist txog tam sim no (21)
