Icandelo lebhayoloji licandelo eliqhelekileyo lokujonga izinto ezifundiswayo kwibhayoloji. Izicubu kunye neeseli zezilwanyana kunye nezityalo zinqunyulwa zibe ziingceba ezincinci ngetekhnoloji ekhethekileyo, emva koko zidaywe, nto leyo elula ukuyibona i-microstructure phantsi kwe-microscope. Ezifana neeseli ze-mesophyll zezityalo kunye neeseli ze-epithelial zezilwanyana zinokuboniswa ngokucacileyo ngecandelo lebhayoloji.
Ngokwembono yenkqubo yokwenziwa, ukucutshungulwa kwezilayi zebhayoloji kunikela ingqalelo kwiinkcukacha. Izinto ezintsha zethishu kufuneka zikhethwe kuqala ukuze kuthintelwe ukubola kweeseli. Ngexesha lenkqubo yokwahlulahlula, ubukhulu becandelo (ngesiqhelo zii-microns ezimbalwa ukuya kwi-ten of microns) buyalawulwa ukuqinisekisa ukuhanjiswa kokukhanya okuhle kwaye kulula ukukubona phantsi kwe-microscope. Kwinkqubo yokudaya, ii-arhente ezifanelekileyo zokufaka imibala ziya kukhethwa ngokweemfuno zokujonga. Umzekelo, i-hematoxylin staining idla ngokusetyenziswa ukujonga i-nucleus, ukuze i-nucleus ibonakale imnyama kwaye yenze umahluko ocacileyo kwi-cytoplasm. Ezinye ii-slides zebhayoloji zivalwe zaza zaqiniswa ngeglasi yokugquma kunye neglu yokutywina ukuze kwandiswe ixesha lokugcina ii-slides kwaye kube lula ukusetyenziswa ngokuphindaphindiweyo.
Ekusetyenzisweni kokufundisa, iislayidi zebhayoloji zifanelekile kwiimfuno ezahlukeneyo zokujonga. Xa befundisa "ulwakhiwo lweeseli" kwisikolo samabanga aphakathi, abafundi banokubona udonga lweseli, i-nucleus kunye nezinye izakhiwo ngokujonga izilayi zeeseli ze-anyanisi epidermal, kwaye baqonde ukwakheka okusisiseko kweeseli. Kwizilingo zezilwanyana zaseyunivesithi, ukujonga icandelo le-meiotic le-locust spermatocytes kunokubona ngokucacileyo inkqubo yokutshintsha kwe-chromosome, enceda ukuqonda indlela yokwakheka kweeseli zentsholongwane. Ukongeza, iislayidi zebhayoloji zingasetyenziselwa imisebenzi yamaqela anomdla ngaphandle kwesikolo, ukuze abafundi bakwazi ukujonga ngokuzimeleyo izicubu ezahlukeneyo zebhayoloji kwaye bahlakulele umdla wabo wokuhlola.
Kwindlela yokugcina izinto zemihla ngemihla, ukugcinwa kwezilayidi zezinto eziphilayo kulula. Ezi zilayidi mazigcinwe kwibhokisi eyomileyo, engakhanyiyo ukuze kuthintelwe ukuba umbala ungaphuki ngenxa yokukhanya kwelanga ngqo. Phatha izilayidi ngobunono ukuze uthintele ukuba iglasi yokugquma ingaphuki; Ukuba kukho uthuli kumphezulu wesilayi, sisule ngobunono ngelaphu elicocekileyo elithambileyo. Olu hlobo lwesilayidi sezinto eziphilayo, olunceda ukujonga izinto ngemicroscope, lwenza ulwazi olungabonakaliyo lwezinto eziphilayo lube lula ukuluqonda ngentetho ecacileyo, kwaye lube sisixhobo esisebenzayo sokufundisa izinto eziphilayo.
