Fucus yog ntau lub cev xim av algae nrog lub neej voj voog piv rau tib neeg (Daim duab 7-9). Cov kab mob is diploid thiab tib lub hlwb haploid yog gametes, uas tuaj nyob rau hauv ob hom: qe loj, unflagellated thiab me me, flagellated phev.
Puas yog Fucus yog Haplontic?
Nws muaj Haplodiplotic life cycle. Lub fucus muaj lub voj voog lub neej diplontic. Ob tug txiv neej thiab poj niam fuse nyob rau hauv ostiole ntawm lub pob.
Ploidy ntawm Fucus yog dab tsi?
Fucus (rockweed), xim av alga, qhia txog keeb kwm ntawm lub neej diploid. Lub zygote ( 2n) dhau los ua embryo (sporophyte hluas heev) thiab loj hlob mus rau hauv cov laus Fucus nrog receptacles ntawm qhov kawg ntawm algae. … Syngamy tshwm sim thaum ob lub fuse thiab dhau los ua zygote (2n).(Nco ntsoov tias tsuas yog gametes yog 1n.)
YPuas yog xim av algae haploid lossis diploid?
Txhua xim av algae muaj ntau lub cellular thiab txhua tus mus dhau ib tiam neeg: diploid (2n) thiab haploid (n) theem alternate.
Lub cev ntawm Fucus yog dab tsi?
Cov nroj tsuag lub cev ntawm Fucus muaj leathery, parenchymatous, dichotomously branched ribbon-zoo li frond, qia-zoo li stipe thiab ib tug basal disc-zoo li holdfast los yog hapteron los ntawm uas nws yog txuas rau lub substratum (Fig. 109A).

Puas yog antheridium haploid lossis diploid?
Antheridium yog ib qho haploid qauv lossis lub cev tsim tawm thiab muaj txiv neej gametes (hu ua antherozoids lossis phev) . Puas yog archegonia haploid lossis diploid? Cov txiv neej thiab poj niam cov kabmob sib deev, antheridia thiab archegonia feem, yog tsim los ntawm cov nroj tsuag gametophytic.
Puas yog fucus protist?
Fucus yog perennial algae, qee qhov muaj lub neej ntev txog plaub xyoos. Lawv muaj cov zais zis zoo li ntab (pneumatocysts), disk-zoo li tus tuav rau clinging rau pob zeb, thiab cov ntaub npog npog uas tiv taus desiccation thiab kub hloov .
Puas yog spores haploid lossis diploid?
Nyob hauv cov nroj tsuag, spores yog feem ntau haploid thiab unicellularthiab yog tsim los ntawm meiosis hauv sporangium ntawm diploid sporophyte. Nyob rau hauv cov xwm txheej zoo, cov spores tuaj yeem txhim kho mus rau hauv cov kab mob tshiab uas siv mitotic division, tsim cov multicellular gametophyte, uas nws thiaj li mus ua gametes .
Puas yog basidiospores haploid lossis diploid?
Basidiospores feem ntau txhua tus muaj ib haploid nucleus uas yog cov khoom lag luam ntawm meiosis, thiab lawv tau tsim los ntawm cov kab mob tshwj xeeb hu ua basidia basidia A basidium (pl., basidia) yog ib hom kab mob fungal. microscopic sporangium (los yog spore-tsim qauv) pom nyob rau hauv hymenophore ntawm fruiting lub cev ntawm basidiomycete fungi uas tseem hu ua tertiary mycelium, tsim los ntawm theem nrab mycelium.
Puas yog xuab zeb yog pob zeb lossis tsis yog?
Qhov tau hais tias, ob pawg tseem ceeb ntawm cov ntawv xuab zeb yog silicon carbide thiab aluminium oxide Nyob rau hauv cov pawg no muaj ntxhib thiab nplua grits muaj, tab sis nws boils mus rau dab tsi ua haujlwm. sandpaper yog siv rau. Almandine yog garnet ntxhia uas feem ntau siv los ua cov ntawv xuab zeb .
