Fungi yog eukaryotes thiab muaj ib complex cellular koom haum. Raws li eukaryotes, cov kab mob fungal muaj a daim nyias nyias -bound nucleus qhov twg DNA yog qhwv ncig histone proteins. Cov kab mob fungal kuj muaj mitochondria thiab complex system ntawm sab hauv daim nyias nyias , suav nrog endoplasmic reticulum thiab Golgi apparatus.
Hais txog qhov no, puas fungi muaj cell phab ntsa?
Cov fungal cell phab ntsa yog tsim los ntawm glucans thiab chitin; thaum glucans kuj pom nyob rau hauv cov nroj tsuag thiab chitin nyob rau hauv lub exoskeleton ntawm arthropods, fungi yog tib yam kab mob uas ua ke ob yam qauv molecules hauv lawv cell phab ntsa . Tsis zoo li cov nroj tsuag thiab oomycetes, fungal cell phab ntsa ua tsis yog muaj cellulose.
Puas muaj fungi muaj cytoplasm? Kab mob cov hlwb zoo ib yam li cov nroj tsuag thiab tsiaj cov hlwb hauv lawv muaj cell membrane, ib tug nucleus, cytoplasm thiab mitochondria. Zoo li cov nroj tsuag cell, fungal hlwb muaj phab ntsa ntawm tes tab sis lawv tsis yog ua los ntawm cellulose, lawv tau ua los ntawm chitin xwb.
Yog li ntawd, dab tsi yog tsib yam ntxwv ntawm fungi?
Cov yam ntxwv ntawm fungi:
- Eukaryotic.
- Decomposers - qhov zoo tshaj plaws recyclers nyob ib ncig ntawm.
- Tsis muaj chlorophyll - tsis photosynthetic.
- Feem ntau multicellular (hyphae) - ib co unicellular (poov)
- Tsis-motile.
- Cell phab ntsa ua los ntawm chitin (kite-in) es tsis txhob cellulose zoo li cov nroj tsuag.
- Muaj feem cuam tshuam rau cov tsiaj ntau dua li cog lub nceeg vaj.
Yuav ua li cas fungal cell membranes txawv ntawm daim tawv nqaij ntawm cov tsiaj?
Fungal cell phab ntsa yog nruj thiab muaj complex polysaccharides hu ua chitin (ntxiv lub zog) thiab glucans. Ergosterol yog steroid molecule nyob rau hauv lub cell daim nyias nyias uas hloov cov cholesterol nyob hauv tsiaj cell membranes . Virus - Lub capsid tiv thaiv lub hauv paus tab sis kuj pab tus kab mob kis tshiab hlwb.
Pom zoo:
Puas yog eukaryotic hlwb puas muaj cov cell membrane?
Zoo li prokaryotic cell, eukaryotic cell muaj plasma membrane, cytoplasm, thiab ribosomes. Txawm li cas los xij, tsis zoo li cov hlwb prokaryotic, cov hlwb eukaryotic muaj: cov membrane-bound nucleus. Muaj ntau cov kab mob uas muaj kab mob (xws li endoplasmic reticulum, Golgi apparatus, chloroplasts, thiab mitochondria)
Vim li cas cov fungi muaj lawv lub nceeg vaj?
Fungi ib zaug tau suav tias yog cov nroj tsuag vim tias lawv loj hlob tawm ntawm cov av thiab muaj cov phab ntsa ntawm tes. Tam sim no lawv tau muab tso rau ntawm lawv tus kheej hauv lawv lub nceeg vaj thiab muaj feem cuam tshuam nrog tsiaj ntau dua li cov nroj tsuag. Lawv tsis muaj chlorophyll ntau rau cov nroj tsuag thiab yog heterotrophic
Cov tsiaj txhu puas muaj lub ntsiab lus zoo thiab cov cell membrane?
Ob lub hlwb cog thiab tsiaj hlwb yog Eukaryotic hlwb. Cov no yog cov hlwb uas muaj cov nucleus uas muaj txiaj ntsig zoo thiab nyob rau hauv uas lwm cov organelles tau tuav ua ke los ntawm daim nyias nyias
Hom cell twg muaj ribosomes thiab cell membranes?
Eukaryotes kuj tseem tuaj yeem ua ib leeg xwb. Ob leeg prokaryotic thiab eukaryotic hlwb muaj cov qauv sib xws. Tag nrho cov cell muaj plasma membrane, ribosomes, cytoplasm, thiab DNA. Lub plasma membrane, lossis cell membrane, yog txheej phospholipid uas nyob ib puag ncig ntawm tes thiab tiv thaiv nws los ntawm ib puag ncig sab nraud
Cov tsiaj puas muaj cov cell membrane?
Tsiaj cov hlwb, xws li cov nyob hauv koj lub cev, muaj cov cell membrane uas tsim sab nraud ntawm tes. Lub cell membrane yog semi-permeable, uas txhais tau hais tias nws tsuas tso cai rau qee yam khoom dhau los
