Qhov Tseem Ceeb Qhov txawv - Fungi vs Protozoa
Nyob rau hauv cov ntsiab lus ntawm cov txheej txheem kev faib tawm niaj hnub no, cov kab mob thiab cov kab mob protozoa yog rau lub Nceeg Vaj Fungi thiab Kingdom Protista raws li lub npe Eukaryotes. Lub Nceeg Vaj Protista tau tsim los txhawm rau txheeb xyuas cov kab mob uas tsis koom nrog lwm pab pawg. Kingdom Protista suav nrog cov nroj tsuag unicellular (algae) thiab tsiaj unicellular. Unicellular tsiaj yog cais raws li protozoa. Kingdom fungi muaj pwm thiab poov xab. Qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov kab mob protozoa yog cov kab mob uas feem ntau yog cov kab mob eukaryotic multicellular thaum protozoa yog cov kab mob unicellular eukaryotic.
Dab tsi yog Fungi?
Fungi belongs rau pawg Eukaryotes uas suav nrog ntau hom tsiaj. Hom fungi feem ntau yog cov poov xab, pwm, thiab nceb. Lub nceeg vaj fungi tuaj yeem muab faib ua tsib qhov tseeb phyla uas yog Chytridiomycota, Zygomycota, Ascomycota, Basidiomycota thiab tsis ntev los no tau piav qhia Phylum Glomeromycota. Cov yam ntxwv feature uas txawv cov fungi los ntawm lwm yam nroj tsuag, ib co protists thiab cov kab mob yog lawv muaj chitinous cell phab ntsa. Fungi yog heterotrophic uas ua rau lawv zoo ib yam li tsiaj. Lawv zais ntau hom digestive enzymes ntawm cov organic teeb meem kom nqus cov zaub mov los ntawm decomposing lawv.
Fungi tsis muaj chlorophyll. Yog li ntawd, lawv tsis photosynthesize. Hauv cov ntsiab lus ntawm kev loj hlob ntawm cov kab mob fungal, lawv ua tiav lawv cov kev xav tau. Hauv cov ntsiab lus yooj yim, lawv txoj kev loj hlob yog lawv txoj kev txav mus los. Lawv kuj tuaj yeem tsim cov spores uas yog flagellated lossis tsis. Flagellated spores ua tiav lawv txoj kev txav mus los ntawm flagella thiab lwm cov spores muaj peev xwm taug kev los ntawm huab cua lossis dej.
Daim duab 01: Fungi – Aspergillus spp.
Fungi tau faib thoob plaws ntiaj teb hauv ntau qhov chaw nyob. Lawv muaj peev xwm nyob rau hauv ib puag ncig huab cua, tab sis feem ntau ntawm cov fungi tsim tau zoo nyob rau hauv lub ntiaj teb ecosystems. Fungi loj hlob raws li hyphae. Fungal hyphae yog cov qauv cylindrical uas ntev 2-10 µm. Lawv muaj xov zoo li filamentous qauv nrog ntev ntawm ob peb centimeters nyob ntawm seb hom. Hyphae muaj peev xwm fuse ua ke thaum lawv los ze zog. Qhov no yog hu ua hyphal fusion. Qhov no ua rau kev loj hlob ntawm mycelium uas yog lub network ntawm hyphae uas muaj kev sib tshuam. Hyphae feem ntau koom nrog hauv kev muab kev loj hlob rau kev loj hlob ntawm fungi los ntawm kev noj cov as-ham los ntawm cov kab mob nyob. Fungal hyphae lossis tsim mycelium tuaj yeem pom los ntawm qhov muag liab qab.
YProtozoa yog dab tsi?
Protozoa yog suav tias yog cov kab mob ib leeg uas yog eukaryotes uas muaj cell nuclei. Lawv kuj qhia cov yam ntxwv zoo nrog tsiaj. Cov yam ntxwv muaj xws li locomotion thiab heterotrophy. Protozoa muaj ntau nyob rau hauv ib puag ncig uas muaj qib siab ntawm noo noo (ib puag ncig aqueous) thiab av uas lawv nyob sib txawv ntawm qib trophic. Protozoa ua tiav lawv txoj kev txav los ntawm kev muaj cilia thiab flagella lossis amoebic txav txawm tias pseudopodia. Cov protozoan uas muaj flagella yog hu ua flagellates. Lawv tuaj yeem muaj ib tus flagellum lossis ntau tus flagella. Ciliates txav vim muaj cov plaub hau zoo li cilia. Raws li tus qauv ntawm kev ntaus ntawm cilia, cov protozoa tuaj yeem hloov kho lawv cov kev taw qhia ntawm txoj kev. Protozoa xws li Amoeba ua tiav locomotion los ntawm pseudopodia. Qee cov protozoa nyob ruaj ruaj thiab lawv tsis txav mus. Cov hom protozoa no raug xa mus rau cov kab mob sessile.
Lawv siv cov txheej txheem sib txawv thiab cov txheej txheem lom neeg los ua kom tiav lawv cov zaub mov xav tau rau lawv txoj kev loj hlob thiab muaj sia nyob. Osmotrophy yog cov txheej txheem lom uas protozoa siv los nqus cov as-ham los ntawm lawv cov cell membranes. Lawv ua phagocytosis los ntawm engulfing cov khoom noj nrog kev pab ntawm pseudopodia. Lawv kuj muaj peev xwm ncaj qha uptake cov khoom noj los ntawm lub aperture zoo li cov qauv uas hu ua cytosome. Cov txheej txheem no zoo ib yam rau ntau hom protozoa hom. Thaum nkag mus rau hauv, cov khoom noj khoom noj tau zom hauv lub vacuole loj uas cov protozoa muaj.
Daim duab 02: Protozoa
Nyob rau hauv lub cell membrane ntawm protozoa, yog lub pellicle uas yog ib tug nyias txheej qauv uas txhawb lub cell membrane thiab nws koom nyob rau hauv pab cov kab mob nyob rau hauv ntau yam uas muaj xws li kev tiv thaiv, khaws lawv cov duab thiab nyob rau hauv hydrodynamics kom yooj yim locomotion.. Cov ntsiab lus ntawm lub pellicle sib txawv ntawm lub cev mus rau lub cev. Yog li ntawd, raws li hom kab mob, lub pellicle tuaj yeem yog elastic hloov tau los yog nruj.
Dab tsi zoo sib xws ntawm Fungi thiab Protozoa?
- fungi thiab protozoa yog heterotrophic.
- Ob hom kab mob muaj flagella rau locomotion.
- Ob hom kab mob no yog eukaryotic.
