Ingxenye yezinto eziphilayo iyisithwali sokubuka esivamile ekufundiseni ngezinto eziphilayo. Izicubu namaseli ezilwane nezitshalo anqunywa abe yizicucu ezincane ngobuchwepheshe obukhethekile, bese efakwa umbala, okulula ukubona isakhiwo esincane ngaphansi kwe-microscope. Njengamaseli e-mesophyll ezitshalo namaseli e-epithelial ezilwane angavezwa ngokucacile ngengxenye yezinto eziphilayo.
Ngokombono wenqubo yokukhiqiza, ukucutshungulwa kwezingcezu zezinto eziphilayo kunaka imininingwane. Izinto ezintsha zezicubu kufanele zikhethwe kuqala ukuze kugwenywe ukuwohloka kweseli. Ngesikhathi senqubo yokuhlukanisa, ubukhulu besigaba (ngokuvamile ama-micron ambalwa kuya kwamashumi ama-micron) kulawulwa ukuqinisekisa ukuhanjiswa okuhle kokukhanya futhi kulula ukukubona ngaphansi kwe-microscope. Enkambisweni yokudaya, ama-agent afanele okufaka imibala azokhethwa ngokwezidingo zokubuka. Isibonelo, ukufaka i-hematoxylin kuvame ukusetshenziselwa ukubona i-nucleus, ukuze i-nucleus ibonakale imnyama futhi yakhe umehluko osobala ne-cytoplasm. Amanye ama-slide ezinto eziphilayo avalwe futhi aqiniswa ngengilazi yokumboza kanye neglue yokuvala ukuze kwandiswe isikhathi sokugcina ama-slide futhi kube lula ukusetshenziswa okuphindaphindiwe.
Ekusetshenzisweni kokufundisa, amaslayidi ezinto eziphilayo afanele izidingo ezahlukene zokubuka. Lapho befundisa “isakhiwo samaseli” esikoleni samabanga aphakathi, abafundi bangabona ngokuzenzakalelayo udonga lweseli, i-nucleus nezinye izakhiwo ngokubuka izingcezu zamaseli e-anyanisi e-epidermal, futhi baqonde ukwakheka okuyisisekelo kwamaseli. Ekuhlolweni kwezilwane zaseyunivesithi, ukubuka ingxenye ye-meiotic yama-locust spermatocytes kungabona ngokucacile inqubo yokushintsha kwe-chromosome, okusiza ukuqonda indlela yokwakheka kwamaseli ezinto eziphilayo. Ngaphezu kwalokho, amaslayidi ezinto eziphilayo angasetshenziswa futhi emisebenzini yamaqembu entshisekelo yangaphandle, ukuze abafundi bakwazi ukubuka ngokuzimela izicubu ezahlukene zezinto eziphilayo futhi bahlakulele intshisekelo yabo ekuhloleni.
Ekulondolozweni kwansuku zonke, ukugcinwa kwama-slide ezinto eziphilayo kulula. Ama-slide kufanele agcinwe ebhokisini elomile, elingangeni ukukhanya ukuze kugwenywe ukufiphala kombala webala elibangelwa ukukhanya kwelanga okuqondile. Phatha ama-slide ngobumnene ukuze uvimbele ingilazi yokumboza ukuthi ingaphuki; Uma kukhona uthuli ebusweni besilayi, sisule ngobumnene ngendwangu ethambile ehlanzekile. Lolu hlobo lwesilayi sezinto eziphilayo, olusiza ekubukeni okuncane kakhulu, lwenza ulwazi olungaqondakali lwezinto eziphilayo lube lula ukuluqonda ngesethulo esinembile, futhi lube ithuluzi eliwusizo lokufundisa ngezinto eziphilayo.
