Qhov Tseem Ceeb Qhov txawv - Sporangia vs Gametangia
Kev tsim tawm yog ob hom; kev yug me nyuam ntawm kev sib deev thiab kev yug me nyuam asexual. Feem ntau ntawm cov fungi qhia asexual reproduction thaum ib co siv kev sib deev kev sib deev. Asexual reproduction yog ua tiav los ntawm kev tsim cov spores. Asexual spores yog tsim nyob rau hauv cov qauv hu ua sporangia. Yog li ntawd, sporangia yog asexual reproductive lub cev. Kev sib deev kev sib deev yog ua tiav los ntawm kev tsim cov hlwb hu ua gametes. Gametes yog haploid, thiab fusion ntawm ob tug txiv neej thiab poj niam gametes tsim ib tug diploid zygote, uas tom qab ntawd tsim mus rau hauv lub cev tshiab. Gametes yog tsim nyob rau hauv cov qauv hu ua gametangia. Qhov sib txawv tseem ceeb ntawm sporangia thiab gametangia yog tias sporangia yog cov qauv kev sib deev uas tsim cov spores asexual thaum gametangia yog cov qauv kev sib deev uas tsim kev sib deev spores lossis gametes.
Sporangia yog dab tsi?
Sporangium (plural - Sporangia) yog ib qho qauv uas tsim cov spores asexual. Sporangia muaj ntau cov nroj tsuag, bryophytes, algae thiab fungi. Spores yog tsim nyob rau hauv lub sporangia los ntawm mitotic los yog meiotic cell divisions. Sporangium tuaj yeem yog ib lub xovtooj ntawm tes lossis multicellular qauv. Sporangia tsim ntau spores thiab tiv thaiv cov spores kom txog thaum lawv loj hlob txaus rau dispersal.
Daim duab 01: Sporangia
Feem ntau ntawm cov sporangia yog kheej kheej lossis cylindrical hauv cov duab. Thaum cov spores npaj txhij rau dispersal, sporangia phab ntsa tawg thiab tso cov spores rau ib puag ncig. Sporangia yog tsim nyob rau hauv sporophytes. Sporophytes yog diploid. Li no, sporangia tsim spores tsuas yog los ntawm meiosis.
Gametangia yog dab tsi?
Gametangium (plural – Gametangia) yog ib qho qauv tshwj xeeb uas gametes tau tsim hauv algae, ferns, fungi thiab nroj tsuag. Gametes yog ob hom; txiv neej gamete thiab poj niam gamete. Lawv yog cov hlwb sib deev. Gametes yog tsim thaum lub sij hawm sib deev. Gametes tsuas muaj ib pawg chromosomes thiab yog li lawv haploid. Thaum ob gametes sib txawv yog fused, nws ua rau lub cell diploid hu ua zygote. Ib tug zygote yog kev sib deev diploid cell, uas tom qab ntawd tsim mus rau hauv ib lub cev tshiab.
Gametangia yog ob hom feem ntau; poj niam gametangia thiab txiv neej gametangia. Poj niam gametangia hu ua archegonia los yog oogonia feem ntau nyob rau hauv algae thiab fungi thiab primitive nroj tsuag nrog rau gymnosperms. Hauv angiosperms, poj niam gametangia hu ua embryo sacs. Poj niam gametangia muab qhov chaw rau fertilization. Txij li cov poj niam gametes (qe hlwb) tsis yog-motile, motile txiv neej gametes ncav cuag poj niam gametangia rau fertilization.
Daim duab 02: Archegonia thiab Antheridia
Txiv neej gametangia raug xa mus ua antheridia. Antheridia tsim cov phev thiab tso tawm rau sab nraud rau syngamy. Gametangia muaj nyob rau hauv gametophytic tiam. Gametophytes yog cov qauv haploid.
Dab tsi yog qhov zoo sib xws ntawm Sporangia thiab Gametangia?
- Sporangia thiab gametangia yog cov qauv kev tsim tawm.
- Ob lub qauv tsim cov spores lossis cov hlwb uas tsim nyog los tsim cov tiam tom ntej.
- Nyob rau hauv ob qho tib si, mitosis lossis meiosis tshwm sim thaum lub sijhawm tsim khoom.
- Ob lub qauv muaj nyob hauv cov kab mob fungi, algae, liverworts, mosses thiab lwm yam.
- Cov spores thiab gametes uas yog tsim los ntawm sporangia thiab gametangia yog haploid.
- Sporangia thiab gametangia tsim cov spores thiab gametes uas tiv taus rau ib puag ncig hnyav.

Summary – Sporangia vs Gametangia
Sporangia thiab Gametangia yog cov kab mob sib kis ntawm ntau pawg kab mob. Sporangia tsim spores. Sporangia feem ntau yog cov qauv asexual uas tsim cov spores asexual. Lawv tuaj yeem yog ib leeg-celled lossis multicellular qauv. Ib tug loj tus naj npawb ntawm spores yog tsim nyob rau hauv lub sporangia, thiab thaum lawv matured, sporangia phab ntsa tawg thiab tso cov spores rau ib puag ncig. Thaum cov spores ua tau raws li cov zaub mov tsim nyog thiab cov xwm txheej, lawv tsim cov kab mob tshiab. Sporangia yog nyob rau hauv cov sporophytes. Gametangia tsim gametes lossis cov hlwb sib deev. Muaj ob hom gametes; txiv neej gametes los yog phev thiab poj niam gametes los yog qe hlwb. Gametangia yog cov qauv kev sib deev. Thiab lawv kuj yog cov qauv haploid. Yog li, gametangia tsim gametes los ntawm mitosis. Gametangia nyob hauv gametophyte. Qhov no yog qhov txawv ntawm sporangia thiab gametangia.
