Key Difference – Zoospore vs Zygote
Cov qauv kev sib txuas sib txawv yog tsim los ntawm ntau hom kab mob hauv lawv lub neej. Lawv txawv cov qauv, tab sis lawv feem ntau sib koom ua ke. Zoospores thiab zygotes yog ob lub ntsiab ntawm cov qauv kev tsim tawm los ntawm cov kab mob. Zoospores yog tsim los ntawm protists, fungi, thiab kab mob. Lawv yog cov motile microscopic asexual spores uas dais flagellum rau locomotion. Ib tug zygote yog ib tug diploid (2n) kev sib deev qauv uas tsis yog-motile thiab tsim vim fusion ntawm ob hom haploid (n) gametes. Qhov sib txawv tseem ceeb ntawm zoospore thiab zygote yog tias zoospores yog tsim thaum lub sij hawm yug me nyuam asexual thaum zygotes raug tsim tawm hauv kev sib deev.
Zoospore yog dab tsi?
Hom kab mob xws li kab mob, protists, thiab fungi tsim motile asexual spores nrog flagella hu ua zoospores. Lub morphology ntawm flagella txawv ntawm kab mob mus rau lwm yam kab mob. Eukaryotic zoospore yog plaub hom morphological sib txawv:
Opisthokont: Lawv muaj ib qho ntev posterior whiplash flagellum.
Anisokont: Lawv muaj ob lub pob zeb whiplash ntawm ob sab ntawm lub cev thiab muaj qhov ntev tsis sib xws.
Zoospore: Lawv muaj ib qho anterior tinsel hom flagellum.
Heterokont: Lawv muaj ib lub tinsel hom flagellum thiab lwm yam whiplash hom flagellum txuas rau sab xub ntiag ntawm kab mob.
Figure 01: Zoospores
Fungal zoospores tsis muaj cov phab ntsa ntawm tes thiab tsis tuaj yeem raug faib. Lawv yog tshwj xeeb rau dispersal thiab rhiab heev rau ntau yam sib txawv ib puag ncig stimuli. Lub zoospore tuaj yeem yog haploid (n) lossis diploid (2n).
Zygote yog dab tsi?
Lub zygote yog eukaryotic diploid (2n) cov qauv kev yug me nyuam uas tau tsim nrog kev sib xyaw ntawm ob haploid (n) gametes los ntawm cov txheej txheem hu ua fertilization. Lub zygote loj hlob mus rau hauv ib tug multicellular kab mob ntawm mitosis. Nyob rau hauv cov ntsiab lus ntawm ib tug unicellular kab mob lub neej voj voog, lub zygote undergoes meiosis, uas ua rau ib tug haploid (n) ib leeg cell kab mob. Hauv fungi, ob lub haploid (n) gametes sib sau ua ke thiab tsim ib lub diploid (2n) zygote los ntawm cov txheej txheem hu ua karyogamy. Raws li hom hom, zygote tuaj yeem raug mitosis lossis meiosis. Nyob rau hauv cov nroj tsuag, fertilization ntawm ob meiotically unreduced gametes (gametes tam sim no nrog ib tug somatic chromosome tooj) ua rau tsim ib tug zygote uas yog polyploid (muaj 3 los yog ntau tshaj chromosomes ntau tshaj li niaj zaus).
Daim duab 02: Zygote
Hauv tib neeg, haploid (n) txiv neej gamete (phev) thiab haploid (2n) poj niam gamete (ovum) fuse los ua ib lub diploid (2n) zygote. Lub zygote tom qab ntawd dhau los ua ntau theem ntawm kev txhim kho uas ua rau muaj cov xeeb ntxwv tshiab.
Zoospore thiab Zygote yog dab tsi?
- Zoospore thiab zygote yog cov qauv tsim thaum lub sijhawm yug me nyuam.
- Ob leeg ua rau kev txhim kho lub cev tshiab.

Summary – Zoospore vs Zygote
Zoospore thiab zygote yog ob hom kev ua me nyuam sib txawv uas tsim los ntawm ntau hom kab mob. Lub zoospores yog asexual microscopic motile qauv uas muaj ib tug flagellum rau locomotion. Lub eukaryotic zoospore muaj plaub lub qauv sib txawv uas txawv morphologically vim muaj ntau hom flagella lawv muaj. Lub luag haujlwm tshwj xeeb ntawm lub zoospore yog dispersal, thiab lawv tau tsim cov txheej txheem sib txawv rau kev hloov pauv. Ib tug zygote yog tshwm sim los ntawm kev sib deev fertilization nyob rau hauv uas ob haploid (n) gametes sib sau ua ke. Lawv yog nonmotile thiab tsis muaj flagella. Ib tug zygote feem ntau yog diploid thiab tsis ua lub luag haujlwm tseem ceeb hauv kev tawg. Qhov no yog qhov txawv ntawm zoospore thiab zygote. Ua cov qauv kev ua me nyuam, ob qho tib si cov qauv sib koom ua ke sib xws thiab ua rau tsim cov xeeb ntxwv tshiab.
