Qhov sib txawv tseem ceeb ntawm zoospore thiab zygospore yog zoospore yog cov qauv haploid thaum zygospore yog cov qauv diploid.
Zoospores thiab zygospores yog ob hom spores tsim los ntawm kev sib xyaw ntawm unicellular gametes. Lawv yog cov qauv kev ua me nyuam. Ntxiv mus, ob hom spores no tshwm sim hauv sporangia. Txawm li cas los xij, zoospores yog swarm spores nrog locomotive peev xwm thaum zygospores tsis-motile.
Zoospore yog dab tsi?
Zoospore yog ib tug flagellated asexual spore tsim los ntawm protists, kab mob, thiab fungi. Lub flagellum muab motility rau zoospore. Lub flagellum tuaj yeem yog ob hom sib txawv: tinsel thiab whiplash. Cov no muaj nyob rau hauv ntau yam kev sib txuas. Tinsel flagella muaj lateral filaments hu ua mastigonemes. Lawv ua raws li lub rudder thiab muab kev ua haujlwm rau lub spores. Whiplash flagellum yog ncaj thiab pab txhawb lub zoospore los ntawm kev tshaj tawm.
Figure 01: Zoospore Types
Muaj plaub yam tseem ceeb ntawm eukaryotic zoospore: opisthokont, anisokont, heterokont, thiab zoospore nrog ib leeg anterior flagella. Opisthokont yog ib qho posterior whiplash flagellum. Nws yog tam sim no nyob rau hauv fungal division Chytridiomycota. Anisokont thiab heterokont yog biflagellate zoospores. Hauv anisokont, ob lub whiplash flagella nrog qhov ntev tsis sib xws. Heterokont muaj ob qho tib si whiplash thiab tinsel flagella.
Zygospore yog dab tsi?
Zygospore yog ib theem diploid ntawm lub voj voog kev ua me nyuam ntawm ntau cov fungi thiab protists. Lawv yog tsim los ntawm haploid hlwb ntawm nuclear fission. Fungal zygospores paub tab nyob rau hauv zygosporangia, ib zaug tshwj xeeb budding qauv yog fused. Cov qauv no tshwm sim hauv mycelia ntawm homothallic fungi lossis hauv ntau hom mating ntawm heterothallic fungi thiab chlamydospores. Tshwj xeeb, cov chav kawm fungal zygomycete tsim cov zygospores hauv lawv cov sporangia nyob rau ntawm qhov kawg ntawm sporangiophores.
Daim duab 02: Zygospore
Nyob hauv eukaryotic algae, zygospores tsim thaum lub unicellular gametes fuse nrog ib leeg. Cov gametes no koom nrog ntau hom kev sib tw. Zygospore ntau lawm yog muaj rau ntau hom Chlorophyta.
Zygospores poob qis vim muaj qhov sib txawv ntawm ib puag ncig xws li lub teeb, tshav kub, noo noo, thiab tshuaj lom neeg los ntawm cov nroj tsuag sib txawv, thiab lwm yam. Txawm li cas los xij, thaum cov xwm txheej zoo rov qab los, zygospore germination tshwm sim. Thaum lub sij hawm zygospore germination, vegetative hlwb raug tsim los ntawm meiosis.
Zoospore thiab Zygospore yog dab tsi?
- Ob lub zoospore thiab zygospore yog ob hom spores.
- Lawv yog cov qauv kev tsim tawm.
- Tsis tas li ntawd, fungi tsim ob qho tib si cov qauv no.
- Ntxiv thiab, ob hom kab mob tshwm sim hauv sporangia.
- Ntxiv mus, unicellular gametes fuse ua ke los tsim ob hom spores.
Qhov txawv ntawm Zoospore thiab Zygospore yog dab tsi?
Zoospore yog ib tug flagellated asexual spore uas tsim los ntawm protists, kab mob, thiab fungi qhov twg flagellum muab motility rau zoospore thaum zygospore yog lub diploid theem ntawm kev loj hlob voj voog ntawm ntau fungi thiab protists tsim los ntawm haploid hlwb ntawm nuclear fission. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm zoospore thiab zygospore. Tsis tas li ntawd, zoospore yog cov qauv haploid thaum zygospore yog cov qauv diploid. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm zoospore thiab zygospore.
Ntxiv mus, qhov sib txawv ntxiv ntawm zoospore thiab zygospore yog qhov zoospore yog ib qho liab qab spore uas tsis muaj cov phab ntsa tseem ceeb, tab sis zygospore muaj cov phab ntsa tuab. Qhov tseem ceeb, zoospores yog motile vim muaj flagella whereas zygospores tsis-motile vim tsis muaj flagella nyob rau hauv lawv. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm zoospore thiab zygospore yog motility.
Summary – Zoospore vs Zygospore
Spores xws li zoospore thiab zygospore yog cov qauv tsim tawm. Zoospores yog asexual spores tsim los ntawm protists, kab mob, thiab fungi. Ntxiv mus, lawv muaj flagella thiab yog motile spores. Nyob rau hauv sib piv, zygospores yog non-motile spores. Lawv yog cov theem diploid ntawm lub voj voog kev ua me nyuam ntawm ntau cov fungi thiab protists. Qhov sib txawv tseem ceeb ntawm zoospore thiab zygospore yog lawv qib ploidy. Zoospores yog haploid thaum zygospores yog diploid.
