Gastrula, early multicellular embryo , muaj li ntawm ob los yog ntau tshaj cov kab mob germinal txheej Ectoderm, sab nraud ntawm peb txheej kab mob, los yog pawg ntawm cov hlwb, uas tshwm sim thaum ntxov ntawm kev loj hlob ntawm tus tsiaj embryo. https://www.britannica.com › science › ectoderm

ntawm cov hlwb uas ntau lub cev tom qab tau txais. Lub gastrula tsim los ntawm lub hollow, ib txheej txheej ntawm cov hlwb hu ua blastula blastula Blastula, hollow sphere ntawm cov hlwb, los yog blastomeres, tsim thaum lub sij hawm kev loj hlob ntawm lub embryo los ntawm rov cleavage ntawm ib tug fertilized. qe. Cov hlwb ntawm blastula tsim ib txheej txheej epithelial (npog) hu ua blastoderm, kaw cov kab noj kua dej, lub blastocoel. https://www.britannica.com › science › blastula

uas nws tus kheej yog cov khoom lag luam ntawm kev faib tawm ntawm tes rov ua dua, lossis cleavage, ntawm lub qe fertilized.
YPuas yog gastrula a blastocyst?
Blastocyst yog ib qho thaum ntxov embryonic theem hauv cov tsiaj txhu(lwm yam nws yog blastula), uas ua raws li kev loj hlob ntawm gastrula. … Blastocyst tau dhau los ua tus txheej txheem hu ua gastrulation uas cuam tshuam nrog kev tsiv teb tsaws ntawm embryonic hlwb thiab gastrula yuav tsim.
peb hom embryo yog dab tsi?
Los ntawm cov txheej txheem ntawm gastrulation, lub embryo sib txawv rau hauv peb hom ntaub so ntswg: ectoderm, ua rau daim tawv nqaij thiab lub paj hlwb; the mesoderm,los ntawm kev tsim cov ntaub so ntswg, cov hlab ntsha, cov leeg, thiab cov pob txha; thiab endoderm, uas ua rau lub plab zom mov, lub ntsws, thiab tso zis.
Cab dab tsi los ua gastrula?
Gastrulation txhais tau tias yog txheej txheem kev loj hlob thaum ntxov uas lub embryo hloov los ntawm ib txheej txheej ntawm epithelial cells(blastula) thiab rov ua dua rau hauv cov txheej txheem ntau thiab ntau qhov chaw hu ua gastrula.
3 txheej kab mob embryonic yog dab tsi?
Peb cov kab mob thawj zaug
Gastrulation yog ib theem tseem ceeb hauv kev loj hlob ntawm embryonic thaum pluripotent qia hlwb sib txawv rau hauv peb txheej txheej kab mob primordial: ectoderm, mesoderm thiab endoderm. Lub ectoderm ua rau cov tawv nqaij thiab lub paj hlwb.

Nyob rau hauv angiosperms, lub nucellus muaj cov embryo sac thiab yog ib puag ncig los ntawm integuments. Puas yog nucellus thiab embryo sac tib yam? Nws muaj peb ntu: kev sib koom ua ke, tsim nws txheej txheej, nucellus (lossis seem ntawm megasporangium), thiab poj niam gametophyte (tsim los ntawm haploid megaspore) hauv nws qhov chaw.

Thaum kawg ntawm 8 lub lis piam tom qab fertilization (10 lub lis piam ntawm cev xeeb tub), lub embryo yog suav tias yog ib tug fetus. Thaum lub sij hawm no, cov qauv uas twb tsim tau loj hlob thiab tsim. Cov hauv qab no yog cov cim thaum cev xeeb tub:

Nws kuj tau qhia tias hnyav fragmented embryos tsis cog [18]. Lwm cov neeg tshawb xyuas tau tshaj tawm tias kev hloov cov embryos nrog cov tawg loj ua rau txo qis kev cog qoob loo thiab cev xeeb tub ntau dua li thaum embryos nrog me me fragmentation tau pauv [

Embryoid lub cev (EBs) yog peb-dimensional aggregates ntawm pluripotent qia hlwb. EBs yog qhov sib txawv ntawm tib neeg embryonic qia hlwb rau hauv lub cev embryoid cuam tshuam peb txheej kab mob embryonic. Qhov txawv ntawm Embryoid thiab embryo yog dab tsi?

theem tom ntej hauv kev loj hlob embryonic yog tsim ntawm lub cev txoj kev npaj. Cov hlwb nyob rau hauv lub blastula rearrange lawv tus kheej spatially tsimpebtxheej ntawm cov hlwb. Cov txheej txheem no hu ua gastrulation. Thaum lub sij hawm gastrulation, lub blastula folds rau ntawm nws tus kheej los tsim peb txheej ntawm cell.
