Tus sporangia (spore case) tshwm sim singly rau ntawm adaxial sab (sab sab sauv rau qia) ntawm nplooj. Cov lycophytes feem ntau dais conelike lug hu ua strobili, uas yog nruj aggregations ntawm sporophylls (sporangium-cov kabmob nplooj).
sporangia nyob qhov twg ntawm sporophyte?
Sporangia tsim cov spores haploid. Cov sporophyte loj hlob los ntawm gametophyte. Lub sporophyte yog diploid thiab gametophyte yog haploid. Sporangia daim ntawv ntawm the underside ntawm gametophyte.
sporangia nyob rau ntawm fern nyob qhov twg?
Fern Sori. Sori (singular: sorus) yog pawg ntawm sporangia (singular: sporangium), uas muaj spores. Sori feem ntau pom nyob rau hauv qab ntawm cov hniav. Cov tub ntxhais hluas sori feem ntau them los ntawm flaps ntawm cov ntaub so ntswg tiv thaiv hu ua indusia (singular: indusium).
Puas muaj sporangia nyob hauv cov ceg?
FUNGI | Txheej txheem cej luam ntawm Kev faib tawm ntawm Fungi
Absidia - pear-puab sporangia ua nyob rau hauv ib nrab whorls ntawm ntu ntu raws li cov ceg ntoo zoo li stolon. Sporangiospores subglobose rau ellipsoid. Cov ceg tsim cov rhizoids ntawm lub sijhawm tab sis tsis tawm tsam cov sporangiophores.
Sporangium yog dab tsi hauv cov nroj tsuag?
A sporangium (pl., sporangia) yog ib tsob ntoo lossis cov kab mob fungal uas tsim thiab muaj cov spores. Sporangia tshwm sim ntawm angiosperms, gymnosperms, ferns, fern phooj ywg, bryophytes, algae, thiab fungi. Lawv spores yogQee zaum hu ua sporangiospores.
