Hua Build: mau 'ike

Ovum - he wahine ke keka aeea, a iloko ona i kakauia he haploid 'ia paha o nā chromosomes. Kona papa kuhikuhiE manao - ka hoolilo ana o aaiaoe 'ike i fertilization. Ka 'ole o ka hua i loko oʻano hiki ke loa e lauwili. No ka laʻana, ka hua manu - e ka iʻa hua, hua manu, etc. Kēlā me kēia? Ueo o ka holoholona i kona mau ano.

Ka 'ole o ka manu hua

Paha ka loa luku ana mamuli o keia 'ole i nā hua o ka manu a me nā mea kolo, a pili i ka like' ole. Hua - he nunui hua manu, i mea oluolu e aʻo me ka kūikawā lako a pan.

Nā manuʻaiʻia hua he o yolk, albumen a me ka iwi. Kēlā me kēia no kēia mau constituent wahi i kona mau ano. Ke yolk mea he anuanu, yellowish, hoʻopoepoe 'ole aia ma ka waena konu o ka hua. Ua loaʻa he hailona o nā bipi kūpaluʻia, nā polokina, nā wikamina, pigments a me nā minelala hao hua. Kona papa kuhikuhiE manao - ka mea, o ka mana o ka embryo.

Top yolk uhiia me ka lahilahi, a anuanu vitellineʻili lahilahi, i ka ili o ka i hiki ke ike i kekahi mea uuku kahi o ka malamalama - he blastodisc, a i ka wahi mua fertilization oocyte nucleus.

Next ka hua manu keokeo, a ua maheleia i eha kala. Ua loaʻa i ka hailona o ke kumuʻiʻo, nā wikamina a me nā minelala hao. Eia hou, aia no he lysozyme - he kūikawā'ūhū, i ka mea he antibacterial hopena. Ma ke kumuʻiʻo, ahu iho i seep wale kinoea.

Kumuʻiʻo lole komoʻuʻuku nona podskorlupovymi mau waihoʻoluʻu ma waena a he mea he uuku nahā i. Shell hua - loa anuanu aiiay iwi hua, a heʻano nui o ka pōhaku paʻapuna. Eggshell hiki i kekahi mau thicknesses a me 'ia nā pōpō - o na ano hiʻona o kēlā me kēia kanaka? Ueo.

Ka 'ole o ke kanaka hua

Women ka hua - he ke keka aeea, a ua waiho waho, aʻoihana kaua i loko o nā follicles o ka ovary. Like nā holoholona, kanaka germ aeea ua papahana e ke hoʻouna i kekahi lākou o nā chromosomes i nā'ōlelo.

Akä naÿe i ka somatic, germ keena hua mai ma ka meiosis, no laila wale pihaʻi me haploid (i loko o kānaka he 23) he lākou o chromosomes. E e ho'ākāka 'ia ma lalo hiʻona o ka' ole o ke kanaka hua.

Ka mua kiʻiona hiʻona - o ka nui. Inā ka maʻamau somatic halepaahao ke keʻena kākaʻikahi aku i 20 micrometers, ke anawaena o ka wahine hua o ka hola 100 microns. Kēia anal aeea mea paʻa a me ka mea i loko o ka follicle a me ka hopena o ko lākou maturation.

Ke'ī mai, me ka 'ole o ka hua manu Ua like i nā keena ma ke kino, - ka mea, ua haku o ka nucleus, cytoplasm, a ua kaupalena i ka wai kokoʻili lahilahi. E like me ua oleloia, o ka haploid nucleus. Ke cytoplasm he he nui helu o ribosomes, mitochondria, a me EPS.

Nō hoʻi, ma ka halepaahao i kōā kaulike haawi ai-kapa yolk granules, a i aeea mana a hiki i kona pōkole i loko o ka uterine paia. Zheltkova Oe piha me ka mahuaola -ʻano nui bipi kūpaluʻia, a me ka uuku o ka nui kumuʻiʻo, nā wikamina a me nā minelala hao.

wahine hua mai i ka 'ole a me kekahi mau hou hiʻona. No ka laʻana, i loko o ka pā bola o ka cytoplasm komo kūikawā secretory granules. Me ka anal o sperm i loko o ka granule Contents ua hoʻokuʻuʻia a me ka hana ma luna o ka iwi o ka hua manu - like me ka hopena, e hoʻololi kona 'ole i loko o ia i ke alanui i ole'ē aʻe sperm hiki ole komo iloko o ia.

Kekahi hana hoihoi 'oiaio o ia ka helu o nā hua i ka wahine ua waiho hoʻi i loko o ka embryonic wā o? Acaeoey. Ua mea i loko o ke au o ka? Acaeoey o na ovaries i loko o ka fetus ua ano e hana i kekahi helu o follicles a me oocytes. I ka hoʻohālike ai i ke kane kino, i ke kaʻina hana o ka kahua o ka spermatozoa, mai puberty, ia mea mau.

E like me 'oe ke ike, i ka' ole o ka hua manu Ua maopopo a me ka mea oo pahuhopu nei me ka mana e hana ia.
