ua haujlwm hauv cov kab mob
…yog ntau lub cev suav nrog, lossis granules, hauv cov kab mob cytoplasm . Cov cev no yeej tsis nyob hauv ib daim nyias nyias thiab ua haujlwm li cov hlab ntsha. Glycogen, uas yog ib tug polymer ntawm qabzib, yog khaws cia raws li ib tug cia ntawm carbohydrate thiab zog.
Tsis tas li ntawd, dab tsi yog suav nrog hauv cov kab mob hauv cov kab mob?
Cov kab mob suav nrog tuaj yeem txhais tau tias yog cov qauv sib cais pom nyob rau hauv cov confines ntawm prokaryotic hlwb , feem ntau intracytoplasmic, tab sis qee zaus nyob rau hauv cheeb tsam periplasmic ntawm lub cell . suav nrog ua haujlwm raws li metabolic reserves, cell positioners, los yog raws li metabolic organelles.
Kuj Paub, cov kab mob twg muaj thiab piav qhia txog lawv txoj haujlwm? Cov kab mob zoo li eukaryotic hlwb uas lawv muaj cytoplasm, ribosomes, thiab cov plasma membrane. Nta uas paub qhov txawv ntawm cov kab mob cell los ntawm eukaryotic cell suav nrog cov DNA ncig ntawm nucleoid, tsis muaj daim nyias nyias-bound organelles, lub cell phab ntsa ntawm peptidoglycan, thiab flagella.
Ib yam li ntawd, tib neeg nug, dab tsi yog lub luag haujlwm ntawm kev suav nrog lub cev?
suav nrog lub cev , qee zaum hu ua elementary cev , yog nuclear lossis cytoplasmic aggregates ntawm cov khoom ruaj khov, feem ntau yog cov proteins. Lawv feem ntau sawv cev rau qhov chaw ntawm cov kab mob sib kis hauv cov kab mob los yog eukaryotic cell thiab feem ntau muaj cov kab mob capsid proteins.
Dab tsi yog txhais los ntawm cell inclusions?
Cell suav nrog . Cell suav nrog yog suav tias yog ntau yam as-ham los yog pigments uas tuaj yeem pom nyob rau hauv cell , tab sis tsis muaj kev ua haujlwm zoo li lwm cov organelles. Piv txwv ntawm cell suav nrog yog glycogen, lipids, thiab pigments xws li melanin, lipofuscin, thiab hemosiderin.

Lub nceeg vaj twg yog ib feem ntawm eukarya thiab tsuas yog suav nrog cov kab mob sib kis?
Muaj cov kev faib tawm: Cov kab mob
Cov kab mob thiab cov kab mob ua haujlwm zoo li cas?
Ob leeg cov kab mob thiab cov kab mob muaj cov phab ntsa ntawm tes (txawm hais tias sib txawv hauv cov qauv thiab muaj pes tsawg leeg) Feem ntau cov kab mob thiab cov kab mob tau txais lub zog los ntawm kev ua pa aerobic (ua pa hauv cov kab mob me ntsis txawv dua li hauv Eukaryotes tab sis cov pa oxygen ib txwm xav tau rau oxidise suab thaj, hauv dej kawg. thiab carbon dioxide yog tsim)
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Cov kab mob dab tsi muaj cov phab ntsa ntawm tes nrog cov protein ntau carbohydrate?
Lub cell phab ntsa ntawm cov kab mob gram-zoo yog peptidoglycan macromolecule nrog cov khoom siv txuas ntxiv xws li teichoic acids, teichuronic acids, polyphosphates, lossis carbohydrates (302, 694)
Yuav ua li cas cov hlwb tshwj xeeb tsim los ua cov haujlwm tseem ceeb hauv ntau cov kab mob?
Multicellular kab mob ua lawv txoj kev ua neej los ntawm kev faib ua haujlwm. Lawv muaj cov hlwb tshwj xeeb uas ua haujlwm tshwj xeeb. Lub Colonial Theory qhia tias kev koom tes ntawm cov hlwb ntawm tib hom coj mus rau kev loj hlob ntawm cov kab mob multicellular
