A microbody (los yog cytosome) yog ib hom kab mob uas muaj nyob hauv cov hlwb ntawm cov nroj tsuag, protozoa, thiab tsiaj txhu. Organelles hauv tsev neeg microbody suav nrog peroxisomes, glyoxysomes, glycosomes thiab hydrogenosomes. Hauv cov kab mob vertebrates, microbodies tshwj xeeb tshaj yog nyob rau hauv lub siab thiab lub raum
Puas microbodies muaj nyob rau hauv prokaryotes?
Qhov chaw: Lawv muaj nyob hauv yuav luag txhua lub hlwb eukaryotic. Lawv feem ntau pom nyob ze ntawm endoplasmic reticulum (ER), thiab qee zaum nyob ze mitochondria thiab plastids. Lawv tsis nyob hauv cov hlwb prokaryotic.
Dab tsi yog microbodies nyob rau hauv ib lub cell?
Microbodies, pom nyob rau hauv hlwb, yog spherical, membrane-bound organelles uas ua si ib feem ntawm photorespiration thiab hloov cov rog rau hauv sucrose. Peroxisomes thiab glyoxysomes yog ob hom microbodies loj hauv cov nroj tsuag.
glyoxysomes nyob qhov twg?
Glyoxysomes yog tshwj xeeb peroxisomes pom nyob rau hauv cov nroj tsuag (tshwj xeeb tshaj yog nyob rau hauv cov rog cia cov ntaub so ntswg ntawm germinating noob) thiab kuj nyob rau hauv filamentous fungi. Cov noob uas muaj roj thiab roj muaj xws li pob kws, taum pauv, paj noob hlis, txiv laum huab xeeb thiab taub dag.
Cov kab mob microbodies hu ua dab tsi?
Peroxisomes, glyoxysomes, thiab glycosomes yog cov cell organelles uas muaj npe hu ua microbodies. Ntawm cov no, peroxisomes tau dav thiab txhais tau tias yog microbodies uas muaj tsawg kawg yog ib qho hydrogen peroxide-tsim oxidase ua ke nrog catalase, uas decomposes hydrogen peroxide sab khoom.

Ntawm qhov chaw twg tsis pom los ntawm qhov pom sab hauv?
Lub qhov ntswg zoo tshaj plawsyog nyob tom qab thiab yog li tsis pom nyob rau sab xub ntiag. Cov duab 9.1, 9.3, 9.5, 9.7, thiab 9.10 N/A Pab txhawb rau anterior cranial fossa; tsim ib feem ntawm qhov ntswg septum thiab qhov ntswg kab noj hniav;
Nyob rau qhov chaw nyob ze rau qhov pom?
Kev nyob ze ze Lub zeem muag Qhov kev pab cuam reflex (lossis nyob ze teb) yog peb feem reflexuas coj cov khoom ze rau hauv kev tsom los ntawm lens thickening, pupillary constriction, thiab sab hauv kev sib hloov ntawm qhov muag-qhov muag convergence.
Qhov qhov muag tsis pom ntawm lub tsheb thauj khoom nyob qhov twg?
Tsev tsheb ciav hlau qhov muag tsis pom muaj xws li: Ncaj nraim rau pem hauv ntej ntawm lub tsheb thauj khoom mus txog 20 ko taw Ncaj nraim hauv qab lub tsheb thauj khoom li 30 ko taw Txhua sab ntawm lub tsheb thauj mus rau sab nraub qaum Tam sim ntawd hauv qab thiab qab tus neeg tsav tsheb qhov rais Puas muaj qhov muag tsis pom kev tsheb thauj mus los?
Qhov kev pom twg pom kev tsis sib haum xeeb yog qhov tsim nyog?
Thaum tib neeg kev sib raug zoo pom tau txais kev sib haum xeeb ntawm lub koom haum ua ib feem tseem ceeb, kev sib cuam tshuam kev pom ntawm-kev tsis sib haum xeeb ntawm lub koom haum yuav siv tib lub tswv yim ib kauj ruam ntxiv. Nws qhia tias qhov kev tsis sib haum xeeb tsis tu ncua, tsawg kawg yog qhov tsim nyog thiab muaj txiaj ntsig zoo rau ib pab pawg .
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
