Kungani kuthiwa ama-embryonic izinso Escape: izici isakhiwo kanye nemvelaphi

Umzimba yiyona ngxenye sithombo esingatshalwanga usesikhundleni ezithile, elinesimo isakhiwo ethile futhi yenza imisebenzi ethile. Omunye wabo izinso. Naphezu kobungako nobuningi bayo encane, ke wenza imisebenzi eminingi ebalulekile. Kungani kuthiwa ama-embryonic izinso ukuphunyuka, uchaze lesi sihloko kafushane.

Isakhiwo izinso

Lokhu umzimba limelela ikusasa simila. Kungani izinso ngokuthi uhlelo of amahlumela embryonic? Zonke ngenxa yokulandelana kwayo ngokohlu. Kumila kuyinto izinso stem-embryonic ludlulele ukukhula Isigaxa. Nazi amaseli lendwangu zemfundo - meristem. Lapho kuqala inkathi evumayo abazaba okukhulu, okubangela ukuthuthukiswa yokuphunyuka.

Cabanga noma yisiphi izinso. Uzothola ukuthi kungaba brown, onsundu ngokuphaphathekile noma abe mpunga, bese ngaphandle embozwe izikali owomile. Lokhu Ushintshe amahlamvu ukuthi ukuvikela yokuphunyuka esizayo ekulimaleni. isithiyo engeziwe ngokumelene kwezimo ezingezinhle kwemvelo resin okuyinto isehlane ihlumela izikali. Kwezinye izitshalo ukuze azivikele okushisa kanye nokuntuleka umswakama, basuke embozwe fuzz obukhulu.

Ngakho, izinso yakhiwa stem ne internodes mfushane (ibanga phakathi amashidi) kanye namahlamvu. Uma uthi nhlá, ngeke bakholwe emva zonke lezi izingxenye zalesi sihlahla kuthiwa ukushintshwa. Yingakho izinso abizwa ngokuthi amahlumela embryonic.

A ezihlukahlukene izinso

amahlumela esingesihle ihlukaniswa ngokweminyaka izimfuneko ezithile. Omunye wabo - ubunjalo isikhundla kwi-stem. Kuye lokhu, izinso kukhona ezilingene apical. Eyokuqala ezinhlangothini isiqu, ngokuvamile in the axils amaqabunga. Kodwa kunokuningi okungakhulunywanga ngakho kule umthetho. Ngokwesibonelo, kalanchoe efihlekile esisogwini emaphethelweni leaf blade. Futhi raspberry - izimpande kanye izingxenye ngaphansi komhlaba sifanamsindvo. Abizwa adventitious efihlekile.

Kungani kuthiwa ama-embryonic izinso ukuphunyuka, thina usuyitholile kakade. Manje ake sibheke imibono yabo nokwakheka singularities.

vegetative efihlekile

uhlobo okunjalo izinso empandni embryonic yakhiwa leaf umklamo. Entwasahlobo, lapho ubude emini inyuka, baqala ukuthuthukisa kuqala. Kungani kuthiwa ama-embryonic izinso yokuphunyuka uchaza futhi yokuthi ngezindleko zabo kukhona ukudla. Vegetative yakha amahlamvu yokuphunyuka esingesihle. Kuyinto kulezi zitho izitshalo Kwenziwa inqubo ye-photosynthesis. Ikakhulukazi kuba entwasahlobo ezidingekayo lapho izihlahla lezihlahla "zingaphila" ngemva kwesikhathi ebusika. Ngokuba ukuthuthukiswa amaqabunga, izimbali, izithelo kanye impande izinhlelo kudingeka amandla. Autotrophs yakha yayo, usebenzisa izibopho amakhemikhali organic compounds, ikakhulukazi i-glucose monosaccharide. Le into ikhiqizwa plastids ka chloroplast eliluhlaza khona amanzi, amandla elanga futhi carbon dioxide. Lesi yisona sizathu esiyinhloko uchaze ukuthi kungani kungenzeka izinso ngokuthi yokuphunyuka esingesihle.

flower efihlekile

Uma ucabangela amahlumela oludala izitshalo bok, ungabona ukuthi akuzona zonke usayizi ofanayo. Labo makhulu, kukhona flower efihlekile. Phakathi kwabo bayatfutfuka izimbali. Kodwa izinso bolshinsvo phezu isitshalo elixutshwe. Bobabili babe nesiqalo futhi izimbali namaqabunga.

Kungani kungase izinso ngokuthi yokuphunyuka esingesihle? Futhi ngoba ngaphandle Ukuphunyuka amandla othola inqubo yokukhula zezitshalo eziphilayo.

Qala zigcwala entwasahlobo esibulalayo efihlekile, sekuqala ukuvela amahlumela. Futhi phakathi nayo yonke inkathi zezitshalo evumayo ikhula ngobukhulu.

izimo ukuthuthukiswa izinso

Development - lena esinye isizathu ukuthi kungani izinso ngokuthi amahlumela embryonic. Ukushisa, umswakama kanye amandla elanga izimo eziyisisekelo efihlekile ziqala ngaphansi kwazo ukuthuthukisa. Amaseli zihlukaniswe zemfundo izicubu kanzima, baphokophelele ishq. Internode elongate, umphumela uba sicu abasha lapho kukhona laluhlata kwetjani. Nge izikali singafi ngokuhamba kwesikhathi, njengoba isidingo ngabo imisebenzi ayisekho.

Uma sitshalo sikhula ngendlela sezulu zone athokomele, ukuthuthukiswa ebusika yezinso zayo kumisiwe. ke waqala entwasahlobo. Ezinye efihlekile khono lingahlala lingasebenzi iminyaka eminingi. Lolu hlobo izitshalo Reserve. Zibizwa ngokuthi ingalali. Uma ezilimele apical yokuphunyuka esingesihle, baqala ukuthuthukisa futhi yakha entsha sifanamsindvo namahlamvu.

Nokusebenza izinso isimo eyinhloko umjikelezo wokuphila. Ukuthuthukiswa listv kokwenza photosynthesis kanye negesi lokushintshisana, izimbali - ukuzala izitho, futhi amahlumela amasha - yilokho imisebenzi ebaluleke kakhulu kulezi izingxenye izitshalo, ngaphandle okuyinto ukukhula nokuthuthuka azinakwenzeka.
