Ubume yesiphaluka wentyatyambo. Iintyatyambo Italasi kwaye dioecious

Kwindalo, kukho imibala ezininzi ezahlukeneyo. Ezinye eqaqambileyo ezintle, enye - ezilula ngokucacileyo. Yintoni na isizathu? Ngaba kunokwenzeka ukuba achaze i-oganogram? Kubonakala ukuba ngenene. Kodwa yintoni ukuchaza scheme? isakhiwo Flower kwizityalo ezahlukeneyo yahluke kakhulu. Kodwa umahluko loqobo alinjalo ngohlobo okanye ubuhle ezinamagqabi bayo. Kakhulu ebalulekileyo oko ngaphakathi kuye.

umsebenzi flower

Ukuze izityalo ziyazala ngokwabo, kufuneka amalungu okuzala. Ukuze wenze oku, ezinye iintlobo baye bafunda ukuba kubekho ubomi entsha esuka ngamasebe ingcambu. Abanye kwavela intyatyambo njengoko organ ngokwesini zaseprayimari ngexesha zazivelela. Yeyona ukuvela kunye ekukhuleni iiseli ezikhokelela emva uvuvuzelo nokwanda yembewu. Umzekeliso ngentla ibonisa isakhiwo uhlobo olufanayo scheme intyatyambo. Kungani ukuba le fom?

Kukholelwa ukuba intyantyambo - yemvelaphi amagqabi. Baya wenza olukhulu engaqhelekanga, njengoko baqhelana neemeko zokusingqongileyo. Abanye "wafunda" lokuzimela ngomungu. Okunye umoya trust. Abanye butshintshe ngendlela efana ukutsala izinambuzane inkangeleko yazo. Bathi, behamba besuka kwenye imbali komnye siyofuna umpe bazamela ukuthwala umungu.

Isakhiwo Scheme wentyatyambo

Yintoni na ilungu lokuzala? Ngokuqhelekileyo, le ntyatyambo ilungu lokugqibela isebe engundoqo iasi eme nkqo okanye lateral. Sibangelwa amathupha kwakheka kwi amahlumelo elifutshane, kwaye awunakuze ube emagqabini. Indawo apho iqala avuke esikhondweni, ebizwa ngokuba isitya. Kuya ekushenxeni kude kuyo "eshiya" ngokwemigaqo olukhulu kwinkqubo yophuhliso ngamabonandenzile.

Ubume wentyatyambo (uhlobo yesekethe ngokubanzi) uyakwazi kuvavanywa umzekelo ifoto ukuba iyalahlwa ngezantsi. It kungabonakala isitya eqinileyo. Ukusuka ikhula perianth. indima yayo zamabanga kwaye nokhuselo kwiindawo ezibalulekileyo kule mbali. Perianth kunokuba ocacile ibe ikomityi kunye phehla. Kunokuba elula unprepossessing, umbala efanayo. Kwaye kwezinye iimeko, yahlulelwe kwii sepals kunye ezinamagqabi eqaqambileyo, izinambuzane kunye zabo.

Yintoni ingakumbi isakhiwo lwangaphakathi wentyatyambo? Scheme izityalo ilungu Italasi ekuzaleni ebonisa ubukho istameni (organelles oyindoda) kunye carpel (ababhinqileyo). Kwakhona ezi iindawo ezingundoqo intyatyambo. Bona apha emazantsi kwisingqusho isiseko ekwanti - maqanda, Ovule equlathe ngasentla - umhlathi ekuthwaleni, phezu kwaso kwincam - Senga. Stamen iquka filament ezingcakacileyo, nto leyo iqhele nkomo.

Italasi and dioecious iintyatyambo

Yintoni na isiseko sale yokuhlela? Yintoni umahluko wabo? Ubume zeesekethe kunye neentyatyambo Italasi dioecious iseti ezahlukeneyo organelles zokuzala. Gqibezela ikhithi busenza ukuba kunye stamens kunye pistil (ulala). Ukuba, ke, eziveliswe kuphela pistil, imbali ingqalelo obhinqileyo, kwaye xa kuphela stamens - inkunzi. Kuzo zombini ezi meko, ukuthetha ngalo amalungu azo okuzala izityalo dioecious.

Yintoni na isakhiwo scheme olukhethekeliyo mbali? Kukho nenye yokuhlela. Ngeentyatyambo bunjalo ishishini kulula, uvuvuzelo yabo lwenzeka ngaphandle naziphi na iingxaki. Ekubeni imeko dioecious kube nzima ngakumbi. Kusenokubakho iinketho ezimbini. Olunye uhlobo iintyatyambo kumgaqo nabakhonzazana, nabakhonzi akhule kunye micingeni mnye (monoecious). Kulo mzekelo, uvuvuzelo kuba lula. Abanye baye inkunzi kunye neentyatyambo nemazi ziveliswa kwi ezahlukeneyo izityalo (dioecious), kwaye zibekwe enye kwenye ezikude kakhulu.

iimpawu

Esi sikimu (structure intyatyambo) kwenza kube lula ukuqonda kakuhle kwisahlulo zezityalo ngumgaqo ngokwesini. iintyatyambo bunjalo (ezinamagqabi), bakholisa ukuba ngaphantsi eliqaqambileyo. Oku kungenxa kufutshane inkunzi organelles ababhinqileyo. Nokuba umntu ezisasaza izinambuzane ngokwaneleyo. Kwezinye zezinto eziphilayo stamens ngokubanzi amalungiselelo ukuze umungu, ubutyobo, xa ufumana phezu pistil. iintyatyambo Dioecious umungu ngokwabo akakwazi. Ngoko ke, zalo zabo imibala eqaqambileyo ukutsala izinambuzane.

Kukho okunye ukuhlelwa. Ezinye izityalo okwentyatyambo ngo-3 - kweeveki ezi-4 emva ayihlwayelayo (yonyaka), ngoxa abanye kuphela kunyaka wesibini okanye wesithathu (ixesha elide). Eminye imithi ukufikelela ngokubanzi ukukhula ngokwesondo kuphela emva kweminyaka elishumi. Enye inxalenye esityalo esezansi ixesha ezinzileyo, abanye (komapile) "ngokwenza" ngalo lonke ixesha. Ngenxa yoko, kunye rhoqo efanayo kukho eya ivuthwa inyukela iziqhamo kunye nembewu.

Kakuhle eli intyatyambo ovula ufikelelo amalungu main okuzala. Njengoko ekukhuleni iiseli intsholongwane lwenzeka kuqala dehiscence ibiselityatyambile. Perianth obala: kuqala, sepals, ezinamagqabi ngoko. Njengoko ukuvuthwa ukufikelela evulekileyo ngokupheleleyo anthers kunye stamens aluthinteli kwimbono ibala noyinkazana umungu eyindoda.
