Key Difference – Txiv neej vs poj niam kab mob Cell
Tib neeg kev yug me nyuam koom nrog cov txiv neej thiab poj niam cov kab mob uas yog cov phev thiab ovum feem. Ob lub hlwb fuse hauv cov txheej txheem hu ua fertilization uas tom qab ntawd txhim kho mus rau hauv cov qauv hu ua zygote. Tom qab ntawd lub zygote yuav loj hlob mus rau hauv ib lub embryo uas ces faib mus rau hauv kev loj hlob ntawm ib tug kab mob. Cov txiv neej kab mob hlwb uas hu ua phev yog synthesized nyob rau hauv lub seminiferous tubules ntawm txiv neej testis, thiab cov poj niam kab mob hlwb uas hu ua ova yog synthesized thiab tsim nyob rau hauv cov poj niam zes qe menyuam. Cov txiv neej kab mob yog heterozygous nrog X thiab Y chromosomes thaum cov poj niam cov kab mob yog homozygous XX chromosomes (ob lub X chromosomes). Nov yog qhov sib txawv ntawm txiv neej thiab poj niam cov kab mob.
Txiv Neej Kab Mob yog dab tsi?
Nyob rau hauv cov ntsiab lus ntawm txiv neej kev yug me nyuam, cov kab mob ntawm cov menyuam yaus hu ua phev. Txiv neej cov kab mob hlwb yog heterozygous nrog muaj X thiab Y chromosomes. Cov phev yog tsim los ntawm cov txheej txheem hu ua spermatogenesis uas tshwm sim nyob rau hauv lub seminiferous tubules ntawm lub testis. Sperm cells tsis muaj peev xwm ntawm kev faib, thiab lawv lub neej luv luv. Cov phev yog tsim nrog lub peev xwm ntawm motility thiaj li ncav cuag poj niam kab mob cell; ovum thiab nkag mus rau nws uas ua tiav cov txheej txheem ntawm fertilization thiab tom qab ntawd txhim kho mus rau hauv cov qauv hu ua zygote. Qee cov phev yog nonmotile, thiab lawv raug hu ua spermatium. Lawv tsis muaj peev xwm ncav cuag ovum thiab fertilize vim tsis muaj motility.
Cov phev tib neeg yog haploid (n) uas muaj 23 chromosomes. Tib neeg phev muaj plaub qhov sib txawv uas suav nrog, lub taub hau, caj dab, nruab nrab daim thiab tus Tsov tus tw. Lub taub hau cheeb tsam yog ib tug ca disc-zoo li tus qauv uas muaj ib tug nucleus tsim ntawm nruj packed chromatin fibers. Ntawm thaj tsam ntawm lub taub hau, muaj cov hloov kho lysosome hu ua acrosome. Nws muaj hydrolytic vesicles uas koom nrog hauv kev degeneration ntawm phab ntsa ntawm lub zes qe menyuam los pab txhawb kev nkag mus thiab fusion ntawm cov phev nrog lub zes qe menyuam. Txawm tias ntau lab tus phev raug tso tawm, tsuas yog ib tus phev yuav fuse nrog lub zes qe menyuam. Lub caj dab cheeb tsam thiab qhov nruab nrab ntawm cov phev muaj ob centrioles, ib tug distal thiab ib tug proximal.
Daim duab 01: Cov kab mob phev
Lub zeem muag centriole cuam tshuam nrog kev sib cais ntawm lub zes qe menyuam. Lub distal centriole muab axial filament 9 + 2 ultra qauv uas tsim ib tug ntev flagellum nrog 9 + 2 ultra qauv; tus tail. Lub caj dab thaj tsam ntawm cov phev uas yog qhov pib ntawm tus flagellum feem ntau muaj mitochondria uas muab lub zog xav tau (ATP) rau kev txav ntawm cov phev los ntawm cov poj niam qhov chaw mos thiab mus cuag cov phev kom tiav. Tib neeg phev muaj s ntev flagellum; tus tail. Nws propels cov phev mus rau pem hauv ntej uas tso cai rau nws mus cuag poj niam ovum. Kwv yees li, 2/3 ntawm tag nrho qhov ntev ntawm cov phev yog them los ntawm tus Tsov tus tw. Nws yog npog los ntawm cov plasma membrane thiab yog surrounded los ntawm cytoplasm.
Poj niam kab mob yog dab tsi?
Nyob rau hauv cov ntsiab lus ntawm poj niam yug me nyuam, lub zes qe menyuam raug suav hais tias yog poj niam kab mob cell uas ua raws li poj niam cev xeeb tub. Lub zes qe menyuam yog haploid (n) nrog 23 chromosomes thiab homozygous nrog muaj XX chromosomes. Thaum tus txiv neej phev sib sau ua ke nrog lub zes qe menyuam, nws loj hlob mus rau hauv cov qauv dhia dej hu ua zygote uas ua tiav cov txheej txheem fertilization.
Daim duab 02: Cov qauv ntawm lub zes qe menyuam
Lub zes qe menyuam yog qhov sib piv ntau dua qhov loj dua thaum piv nrog tib neeg phev. Nws yog nonmotile. Lub zes qe menyuam yog ib puag ncig los ntawm cov txheej txheem sib txawv. Lub innermost pob tshab txheej yog hu ua vitelline membrane uas yog tsim los ntawm ovum. Sab nraud rau vitelline daim nyias nyias yog lub zona pellucida, uas yog tuab tsis yog cellular membrane. Zoo ib yam li vitelline daim nyias nyias, lub zona pellucida yog pob tshab. Nyob nruab nrab ntawm ob txheej ntawm tes, vitelline membrane thiab zona pellucida, qhov chaw nqaim yog tam sim no uas yog hu ua qhov chaw perivitelline. Sab nraud mus rau zona pellucida, ib txheej tuab ntawm cov xov tooj ntawm tes yog tam sim no hu ua corona radiata. Nws yog tsim los ntawm granulosa hlwb los yog follicular hlwb. Qhov kev txiav txim ntawm acrosome yuav pib nkag mus los ntawm granulosa hlwb ua ntej uas tom qab ntawd zom rau hauv cov txheej txheem ntawm tes.
Lub nucleus ntawm ovum yog nyob rau hauv nruab nrab ntawm lub cell. Nws yog embedded nyob rau hauv ib tug cytoplasm uas muaj ib tug tshwj xeeb tshuaj hu ua york. Nws tseem hu ua vitellus. Nws muab cov khoom noj uas yuav tsum tau ua rau lub zes qe menyuam thiab cov embryo loj hlob thaum cov txheej txheem fertilization tiav. Raws li tus nqi ntawm york tam sim no nyob rau hauv lub qe qe nyob rau hauv ntau yam kab mob, lawv muaj peb hom; microlecithal, tsawg npaum li cas ntawm york nyob rau hauv me me ovum; mesolecithal, ovum tam sim no nrog ib tug nruab nrab ntawm york thiab macrolecithal nrog ib tug loj npaum li cas ntawm yolk. Tib neeg ovum yog microlecithal. Vim lub eccentric positioning ntawm lub nucleus, tib neeg ovum, nws tsim polarity.
Dab tsi zoo sib xws ntawm txiv neej thiab poj niam kab mob?
- Ob leeg koom nrog hauv cov txheej txheem ntawm kev yug me nyuam uas cov phev cell sib sau ua ke nrog lub zes qe menyuam uas txhim kho mus rau hauv kev faib cov qauv hu ua zygote los ntawm fertilization.
- Ob lub hlwb yog haploid (n) nrog 23 chromosomes.

Summary – Txiv neej vs poj niam kab mob
Cov txiv neej thiab poj niam cov kab mob sib sau ua ib lub zygote los ntawm cov txheej txheem hu ua fertilization. Qhov no yog ib kauj ruam tseem ceeb hauv kev tsim noob neej. Cov phev, txiv neej kab mob ntawm tes yog tsim los ntawm plaub (04) cov qauv sib txawv xws li disc-shaped flattened taub hau, caj dab, nruab nrab daim thiab tus Tsov tus tw. Nyob rau thaj tsam ntawm lub taub hau, muaj cov hloov kho lysosome hu ua acrosome uas muaj hydrolytic vesicles uas koom nrog hauv kev degeneration ntawm phab ntsa ntawm lub zes qe menyuam. Lub zes qe menyuam yog cov qauv kheej kheej nrog cov txheej txheem sib txawv ntawm cov cell hauv ob sab phlu uas npog lub zes qe menyuam. Lub nucleus nyob eccentrically. Ob lub hlwb yog haploid (n) nrog 23 chromosomes. Qhov sib txawv tseem ceeb ntawm cov txiv neej thiab poj niam cov kab mob yog Txiv neej cov kab mob yog heterozygous nrog X thiab Y chromosomes whereas cov poj niam cov kab mob yog homozygous nrog ob X chromosomes.
