Isithombe: I-High-Resolution Micrograph Yamaseli Afufusayo Eyeast

Isithombe siwumfanekiso oseduze, onokucaca okuphezulu wamaseli eyeast abonwe ngaphansi kwesibonakhulu, ogcizelela ubunkimbinkimbi nobuhle bezwe elincanyana. Ukugxila okumaphakathi kuyiseli elikhulu, elimise okweqanda leyeast elithathwe phakathi kokuhluma okusebenzayo, inqubo yokuzala enobunono futhi ebalulekile ekuvuthweni. Ingqamuzana elincanyana, eliyindilinga lendodakazi liphuma endaweni yalo, elicishe liphelele kodwa lisaboshelwe kuseli lomzali, kuyilapho elinye ihlumela liqala ukuvela endaweni ehlukile. Le phethini yokuhluma okumbaxambili inikeza umbono wokukhula okuguquguqukayo nokwehlukana, okuyibonisa kahle indlela imvubelo esakazeka ngayo.

Imininingwane esodongeni lwamaseli iyamangalisa: ukuthungwa kwayo okungaphezulu kubonakala kune-dimpled, cishe ku-velvety, okubonisa ukwakheka okuyingqayizivele kwemvubelo. Umbala osagolide-tan wamaseli ugezwe ngokukhanya okuthambile, okuqondisayo okuthuthukisa ikhwalithi yawo enezinhlangothi ezintathu. Ijika ngalinye nekhonsathi ibamba okuvelele okucashile, kuyilapho izithunzi ezithambile ziboleka ukujula nokuba ngokoqobo. Ukusebenzisana kokukhanya nokuthungwa kuvumela umbukeli ukuthi abone iseli hhayi nje njengeyunithi yebhayoloji engabonakali, kodwa njengenhlangano ephilayo, ephilayo ehileleke enqubweni ebalulekile ye-metabolic.

Kuzungeze iseli elihlumayo elimaphakathi inkambu yamanye amaseli emvubelo, anikezwe ngokugxila okuthambile ngenxa yokujula kwensimu engajulile. Lawa maseli ayahluka ngosayizi nangomumo, okuphakamisa inani labantu abasezigabeni ezihlukene zomjikelezo wabo wokuphila. Ezinye ziyindilinga ngokuphelele, ezinye zibude kancane, kanti ezimbalwa zibonakala zisemagatsheni okuqala okuhluma. Amaseli angemuva angagxilile akha umuzwa wokujula nokwendlaleka kwendawo, kuyilapho eqinisekisa ukuthi iso lesibukeli likhangwa esihlokweni esingaphambili esibukhali, esinemininingwane.

Ingemuva elilufifi ngokwalo liphethe ithoni ethulisiwe esagolide-beige, engenazo iziphazamiso ezibonakalayo, eqinisa injongo yesayensi yesithombe. Lokhu kusetshenziswa ngokucophelela kokugxila okukhethiwe kubonisa umuzwa wokulunguza ngesibonakhulu, lapho indinyana encane yokucaca ihlukanisa iseli eyodwa noma iqoqo ngokumelene nendawo ebanzi, engacacile. Idlulisa kokubili ukunemba kwe-microscopy kanye nokusondelana okujulile kokutadisha izinto eziphilayo ezingeni lamaselula.

Ngokwesayensi, isithombe sibonisa okungaphezu nje kwe-morphology-sithwebula ingqikithi ye-yeast dynamics ekuvubeleni. Amaseli ahlumayo amelela ukukhula okunamandla, ukuphindaphinda okungaphansi kwamazinga emvubelo, ukuncipha, namandla kuzimo zokukhiqiza. Kusebenza njengesikhumbuzo esibonakalayo sokuthi yonke ipinti kabhiya, isinkwa ngasinye, sikweleta uhlamvu lwaso ngenxa yokuphindaphindeka okungabonakali okufana nalokhu okungafi lapha.

Ithoni yokubunjwa ingokwesayensi neyobuhle. Ukulungiswa okuhlanzekile nokucaca kobuchwepheshe kwenza isithombe silungele izinjongo zemfundo, ukukhombisa ukwakheka kwamaselula nokukhiqizwa kabusha. Ngesikhathi esifanayo, ukufudumala kokukhanya kanye nefreyimu yobuciko kuyayiphakamisa ngaphezu kwemibhalo ehlanzekile ibe yinto ecishe ibe yimifanekiso eqoshiwe. I-yeast cell ayibi nje indaba yokufunda kodwa ibe yinto yobuhle, ehlanganisa ubuciko obufihliwe besayensi yezinto eziphilayo.

Empeleni, isithombe sivala igebe phakathi kwesayensi yaselabhorethri nobuciko obubonakalayo. Idlulisa ubungqabavu be-yeast ekusebenzeni, ukunemba kwe-microscope, nobuhle bomklamo wemvelo. Ngokugxila engqamuzaneni elilodwa lemvubelo elisafufusa phakathi kwenani labantu elifiphele, likhipha inkimbinkimbi yempilo yamagciwane kusikhathi esicacile, esifinyelelekayo, okuvumela ababukeli ukuba babone kokubili imininingwane yobuchwepheshe yokuvutshelwa kanye nokumangalisa kobuhle besayensi yezinto eziphilayo.
