Qhov sib txawv tseem ceeb ntawm lichen thiab mycorrhizae yog tias lichen yog kev sib koom ua ke uas muaj nyob nruab nrab ntawm algae / cyanobacterium thiab fungus, thaum mycorrhiza yog ib hom kev sib koom ua ke tshwm sim ntawm cov hauv paus ntawm cov nroj tsuag siab dua thiab cov kab mob fungus.
Kev Sib Koom Tes yog ib qho ntawm peb hom symbiosis uas tshwm sim ntawm ob hom kab mob sib txawv. Tsis zoo li lwm yam ob hom, kev sib nrig sib pab cuam rau ob qho tib si cov neeg koom tes hauv kev koom tes. Lichen thiab mycorrhizae yog ob qho piv txwv ntawm kev sib koom ua ke. Ob leeg yog ecologically kev sib raug zoo. Ob tog ntawm lichen yog algae lossis cyanobacterium thiab fungus. Ntawm qhov tod tes, ob tog ntawm mycorrhizae yog cov hauv paus hniav ntawm cov nroj tsuag siab dua thiab cov kab mob fungus.
Lichen yog dab tsi?
Lichen yog kev sib raug zoo uas muaj nyob nruab nrab ntawm algae / cyanobacterium thiab fungus. Hauv lub koom haum no, ib tog yog lub luag haujlwm rau kev tsim cov khoom noj los ntawm photosynthesis thaum lwm tog yog lub luag haujlwm rau kev nqus dej thiab muab vaj tse. Photobiont yog tus khub photosynthetic ntawm lichen. Nws yog lub luag haujlwm rau kev tsim cov carbohydrates lossis zaub mov los ntawm photosynthesis. Nws tuaj yeem yog ntsuab alga lossis cyanobacterium. Ob leeg muaj peev xwm ua tau photosynthesis vim lawv muaj chlorophylls.
Daim duab 01: Lichen
Txawm li cas los xij, thaum piv cov algae ntsuab thiab cyanobacteria, algae pab txhawb ntau rau kev tsim cov lichens nrog fungi dua cyanobacteria. Mycobiont yog tus khub fungal ntawm lichen. Nws yog lub luag haujlwm rau kev nqus dej thiab muab ntxoov ntxoo rau photobiont. Feem ntau, cov fungi ntawm ascomycetes thiab basidiomycetes tsim hom kev sib koom ua ke nrog algae lossis nrog cyanobacteria. Feem ntau, hauv lichen, tsuas yog ib hom fungi tuaj yeem pom - nws tuaj yeem yog ascomycete lossis basidiomycete. Lichens tuaj yeem pom ntawm tsob ntoo tawv ntoo, cov pob zeb raug, thiab kuj yog ib feem ntawm cov av crust. Tsis tas li ntawd xwb, lichens tuaj yeem muaj sia nyob hauv qhov chaw huab cua xws li khov rau sab qaum teb, cov suab puam kub, cov ntug dej hiav txwv pob zeb, thiab lwm yam.
Lichens muab ntau lub luag haujlwm tseem ceeb. Lawv rhiab heev rau lawv ib puag ncig. Yog li, lawv tuaj yeem qhia qhov tshwm sim xws li kev ua qias tuaj, ozone depletion, hlau paug, thiab lwm yam., ua raws li kev ntsuas ib puag ncig. Tsis tas li ntawd, lichens tsim cov tshuaj tua kab mob ntuj uas tuaj yeem siv los ua tshuaj. Tsis tas li ntawd, lichens muaj txiaj ntsig zoo rau kev ua cov tshuaj tsw qab, tshuaj pleev xim, thiab tshuaj ntsuab.
Mycorrhizae yog dab tsi?
Mycorrhiza yog lwm qhov piv txwv ntawm kev sib raug zoo. Nws tshwm sim ntawm cov hauv paus hniav ntawm cov nroj tsuag siab dua thiab cov fungus. Cov fungus nyob hauv cov hauv paus hniav ntawm cov nroj tsuag siab dua yam tsis ua mob rau cov hauv paus hniav. Cov nroj tsuag siab dua muab zaub mov rau cov fungus thaum fungus absorbs dej thiab as-ham los ntawm cov av mus rau cog. Yog li ntawd, qhov kev sib koom ua ke no muab txiaj ntsig zoo rau ob tus neeg koom tes. Mycorrhizae yog qhov tseem ceeb ntawm ecologically. Nws yog vim hais tias thaum cov cag ntoo tsis nkag mus rau cov as-ham, fungal hyphae tuaj yeem loj hlob ob peb meters thiab thauj cov dej thiab cov as-ham, tshwj xeeb tshaj yog nitrogen, phosphorus, potassium mus rau cov hauv paus hniav. Yog li ntawd, cov tsos mob ntawm cov as-ham tsis tshua muaj tshwm sim nyob rau hauv cov nroj tsuag uas nyob rau hauv no symbiotic koom haum. Kwv yees li 85% ntawm cov nroj tsuag vascular muaj cov koom haum endomycorrhizal. Tsis tas li ntawd, fungus tiv thaiv cov nroj tsuag los ntawm cov kab mob hauv paus. Yog li ntawd, mycorrhizae yog cov koom haum tseem ceeb hauv ecosystems.
Daim duab 02: Mycorrhizae
Ectomycorrhizae thiab endomycorrhizae yog ob yam tseem ceeb ntawm mycorrhizae. Ectomycorrhizae tsis tsim arbuscules thiab vesicles. Ntxiv mus, lawv hyphae tsis nkag mus rau hauv lub cortical hlwb ntawm cov nroj tsuag hauv paus. Txawm li cas los xij, ectomycorrhizae tseem ceeb heev vim tias lawv pab cov nroj tsuag los tshawb nrhiav cov as-ham hauv av thiab tiv thaiv cov cag ntoo los ntawm cov kab mob hauv paus. Meanwhile, nyob rau hauv endomycorrhizae, fungal hyphae nkag mus rau hauv lub cortical hlwb ntawm cov nroj tsuag keeb kwm thiab tsim vesicles thiab arbuscules. Endomycorrhizae yog ntau tshaj li ectomycorrhizae. Cov fungi los ntawm Ascomycota thiab Basidiomycota koom nrog tsim ectomycorrhizal koom haum thaum fungi los ntawm Glomeromycota koom nrog hauv kev tsim endomycorrhizae.
Dab tsi zoo sib xws ntawm Lichen thiab Mycorrhizae?
- Lichen thiab mycorrhizae yog ob hom kev sib raug zoo ntawm kev sib raug zoo uas muaj nyob ntawm ob hom sib txawv.
- Ntxiv mus, ob qho tib si kev sib koom tes ib txwm muaj cov kab mob fungus.
- Ob tog tau txais txiaj ntsig ntawm ob txoj kev sib raug zoo.
- Tsis tas li ntawd, ob qho tib si lichen thiab mycorrhizae yog ib qho tseem ceeb rau ecosystem sustenance.
Qhov txawv ntawm Lichen thiab Mycorrhizae yog dab tsi?
Lichen thiab mycorrhizae yog ob qho kev sib raug zoo ntawm kev sib raug zoo. Lichen tshwm sim ntawm cov kab mob thiab cov kab mob cyanobacterium lossis ntsuab alga thaum mycorrhiza tshwm sim ntawm cov fungus thiab cov hauv paus hniav. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lichen thiab mycorrhizae. Tsis tas li ntawd, feem ntau ascomycetes thiab basidiomycetes koom nrog hauv kev tsim cov lichens, thaum basidiomycetes, glomeromycetes thiab ob peb ascomycetes koom ua mycorrhizae. Yog li ntawd, qhov no kuj yog qhov txawv ntawm lichen thiab mycorrhizae.
Summary – Lichen vs Mycorrhizae
Lichen yog ib qho kev koom tes ntawm alga / lossis cyanobacterium thiab fungus. Ntawm qhov tod tes, mycorrhiza yog kev sib koom ua ke ntawm cov kab mob thiab cov hauv paus hniav ntawm cov nroj tsuag siab dua. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lichen thiab mycorrhizae. Ob lub koom haum yog cov piv txwv ntawm kev sib nrig sib. Thiab lawv muaj qhov tseem ceeb ntawm ecological ib yam nkaus.
