Dab tsi yog a Sporangium ? A sporangium yog astructure hauv qee cov nroj tsuag thiab lwm yam kab mob uas raug them nrog kev tsim thiab khaws cov spores. Spores yog cov qauv haploid tsim nyob rau hauv cov kab mob uas pab kom germinate thiab tsim cov kab mob tshiab. Ib lo lus, lawv pab cov kab mob kom rov tsim dua.
Ntawm no, lub luag haujlwm ntawm Strobilus yog dab tsi?
Lub spirally txheej txheem sporophyll ntawm lub strobilus Dais spores nyob rau hauv lawv sporangium. Cov spores ntawm germination ua rau nce mus rau gametophytic tiam. Cov strobilus yog suav hais tias yog ib qho kev tsim menyuam yaus uas muaj cov kabmob spores.
Tsis tas li ntawd, qhov txawv ntawm Sporangia thiab Sporangium yog dab tsi? Raws li lub npe Qhov sib txawv ntawm sporangia thiab sporangium yog tias sporangia yog thaum sporangium yog (botany|mycology) ib rooj plaub, tshuaj ntsiav, los yog thawv uas spores yog tsim los ntawm ib tug kab mob.
Tsis tas li ntawd, dab tsi yog Sporangia hauv cov nroj tsuag?
A sporangium (pl., sporangia ) (modernLatin, los ntawm Greek σπόρος (sporos)'spore' + ?γγε?ον (angeion)'vessel') yog ib qho chaw nyob rau hauv uas spores raug tsim. Nws tuaj yeem tsim los ntawm ib lub xov tooj ntawm tes lossis tuaj yeem ua ntau lub cell. Tag nrho nroj tsuag , fungi, thiab ntau lwm yam kab mob sporangia ntawm qee lub sijhawm hauv lawv lub neej voj voog.
Puas yog Sporangium yog Sporophyte lossis Gametophyte?
Hauv sporophytes , nws tshwm sim hauv cov qauv hu ua sporangia ( sporangium yog ib qho lus). Thaum spores yog tsim nyob rau hauv a sporangium , lawv feem ntau tso rau saum huab cua. Ib qho haploid spore yuav raug mitosis, lossis cell division yam tsis muaj qhov txo qis ntawm chromosome, los ua ib tug multicellularhaploid. gametophyte.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Lub luag haujlwm ntawm lub cell membrane yog dab tsi thaum lub sijhawm thauj mus los?
Lub cell membrane yog xaiv permeable rau ions thiab organic molecules thiab tswj kev txav ntawm cov khoom hauv thiab tawm ntawm lub hlwb. Lub luag haujlwm tseem ceeb ntawm cov cell membrane yog los tiv thaiv lub cell ntawm nws ib puag ncig. Nws muaj phospholipid bilayer nrog embedded proteins
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
