Kwai Build: general bayanai

Ovum - mace jima'i cell, wanda ya ƙunshi wata haploid sa na chromosomes. Its main nufi - da canja wurin da kwayoyin bayanai a lokacin hadi. A tsarin da kwai a cikin yanayi za a iya quite bambanta. Alal misali, kwai - yana da kifi qwai, kwai, da dai sauransu Kowane jinsi na dabba yana da halaye.

A tsarin da tsuntsu kwai

Zai yiwu mafi daukan hankali misali na wannan tsarin ne da qwai tsuntsaye da dabbobi masu rarrafe, wanda sun fi mayar da irin wannan tsarin. Kwai - wata babbar kwai, wanda shi ne sauki koyi ba tare da musamman kayan aiki.

Kaji qwai kunshi gwaiduwa, albumen da kuma harsashi. Kowace daga cikin wadannan bijiro da batun kafa sassa na da halaye. Gwaiduwa ne m, yellowish, madauwari tsarin dake a cikin cibiyar da kwai. Ya ƙunshi abubuwa da yawa na fats, sunadarai, bitamin, pigments da kuma ma'adanai qwai. Its main nufi - shi ne ikon da tayi.

Top gwaiduwa an rufe shi da wani bakin ciki da kuma m vitelline membrane, da farfajiya na wanda za a iya gani a kananan tabo haske - wani blastodisc, abin da yake a wurin kafin hadi oocyte tsakiya.

Next ne kwai fari, wanda ya kasu cikin hudu bukukuwa. Ya ƙunshi abubuwa da yawa na gina jiki, bitamin da kuma ma'adanai. Bugu da kari, akwai wani lysozyme - musamman enzyme, wanda yana da wani antibacterial sakamako. Ta hanyar gina jiki Layer iya seep kawai gas.

Protein mai rufi podskorlupovymi biyu bukukuwa tsakanin abin da akwai kananan rata. Shell Qwai - sosai m m harsashi qwai, wanda ya kunshi gaske na alli carbonate. Eggshell iya samun daban-daban thicknesses da kuma canza launi - shi ne halayyar siffofin kowane mutum jinsunan.

A tsarin da mutum qwai

Mata kwai - mai jima'i cell, wanda aka adana da kuma balaga a cikin follicles da kwai. Kamar dukan dabbobi, mutum jam cell da aka tsara don aika da wani sa na chromosomes a lokacin haifuwa.

A bambanci ga somatic, jam sel samar da meiosis, don haka ne kawai dauke da haploid (a cikin mutane shi ne 23) wani sa na chromosomes. Features na tsarin mutum qwai za a iya bayyana a kasa.

A farko rarrabe - ne size. Idan al'ada somatic cell bangaren da wuya ya wuce 20 micrometers, da diamita na mace kwai ne kamar 100 microns. Wannan jima'i cell ne mai ƙayyadadden ajali kuma shi ne a cikin follicle har zuwa karshen su maturation.

Saboda haka, tsarin da kwai ne kama da sauran Kwayoyin a cikin jiki - shi ne hada a tsakiya, cytoplasm, kuma aka iyakance zuwa cikin jini membrane. Kamar yadda aka ambata riga, da haploid tsakiya. A cytoplasm ƙunshi wata babbar lamba na ribosomes, mitochondria, kuma EPS.

Har ila yau, a ko'ina cikin cell an ko'ina rarraba da ake kira gwaiduwa granules, da samar cell ikon har da gabatarwar a cikin igiyar ciki bango. Zheltkova kumfa cika da na gina jiki - yafi fats da kuma karamin adadin furotin, bitamin da kuma ma'adanai.

mace kwai yana da wani tsari da kuma wasu karin fasali. Alal misali, a cikin matsanancin kwano na cytoplasm dauke da musamman secretory granules. Tare da shigar azzakari cikin farji daga maniyyi a cikin granule abinda ke ciki aka saki da kuma abubuwa a kan harsashi na kwai - a sakamakon, shi ya canjãwa da tsarin a cikin irin wannan hanyar da ba sauran maniyyi ba zai iya shiga da shi.

Wani mai ban sha'awa Gaskiyar ita ce, da yawan qwai a mace ne ya sa a baya a zamanin tayi zai kare na ci gaba. Yana da yake a cikin lokaci na ci gaba da ovaries a tayin da aka riga ya kafa wani yawan follicles da oocytes. Lokacin da idan aka kwatanta da namiji jiki, da aiwatar da samuwar ma'ana, tun lokacin balaga, shi ne m.

Kamar yadda ka gani, da tsarin da kwai ne quite takamaiman kuma Shi ne Mafi m tare da ayyuka da suka yi da shi.
