Uyini vacuole: izinhlobo kanye nezici izakhiwo

Amaseli zezitshalo nezilwane aqukethe ezihlukahlukene izakhiwo ukuthi enze nokugcinwa imisebenzi ako. Omunye wabo vacuole. Phakathi kwabo, babe ezinye umehluko omkhulu. Kulesi sihloko uzofunda ukuthi vacuole nokuthi kungani kudingeka ukuba izinto eziphilayo.

Permanent iseli isakhiwo

vacuoles Ngokuthi odnomembrannye organelles, nezitshalo nezilwane amaseli. Ezinye zazo yilezi idlula, kuyilapho abanye avele njengoba benjalo isidingo sokusebenza. Kuye isakhiwo esithile kulezi organelles bayakwazi ukugcina umsoco, uhlukanise kubo futhi yenza umsebenzi wokulawula.

izinhlobo izakhiwo

Kukhona izinhlobo ezintathu vacuoles. Ngo isitshalo amaseli contractile futhi wokugaya ukudla. Bona lokulawula ingcindezi osmotic, kukhishelwa ngaphandle izinsalela undigested futhi enze umsebenzi secretory. Kodwa izitshalo kukhona amathangi amakhulu aqukethe amanzi, okuyinto ziyoncibilika yonke impahla cell.

Vacuoles plant amaseli

Ngo plant cells abasha, lezi zakhiwo kungase hlala kakhulu konke okuqukethwe kwangaphakathi. Futhi kulula ukuchaza. Ngempela, umzimba ezikhulayo kudingeka eningi ejenti isipele ukuthuthukiswa. Uyini vacuole zezitshalo amaseli? Lokhu odnomembrannye amathangi amakhulu nge cell ubisi. Lesi sakamuva kuyinto amanzi nge carbohydrate oncibilikile izinsalela izinto neorganichskih. Isakhiwo ubisi cell sihlanganisa ezihlukahlukene imikhiqizo umzimba. Kungaba alkaloids, tannins. Kukhona futhi eba nezakhi zombala ezenza ukuthi ukunikeza umbala ezingxenyeni ezahlukene simila. Ngakho, vacuole kuseli isitshalo udlala indima "ithala".

contractile vacuole

Isakhiwo vacuole, okuyinto eyenza umsebenzi zokulawula abaphila ngayo ihluke ngokuphelele. Eziningi zalezi izakhiwo ezitholakala emangqamuzaneni emachibini protozoan zasolwandle. Uyini vacuole, okuyinto lokulawula turgor cell? Zimelela ibhamuza onesigqi, esemgwaqweni emhlabeni inethiwekhi ijabulise. Le ndlela zokuthutha uketshezi. Ngokusho tubules ketshezi ngokweqile kuqala livela cytoplasm phakathi vacuole, kodwa ngoba kakade iye isiphelile ngaphandle.

akazange kuphi ukuthola uketshezi olunqwabelene kuseli nokuthi kungani kudingeka zisuswe? Zonke daba imithetho yemvelo. Ngokusho kwabo, le nhlangano senzeka kusuka esifundeni lokuhlushwa ngaphezulu ukuze aphansi. Njengoba nosawoti imvelo amanzi ngaphezulu uqala kuthunyelwe esitokisini. ebusweni unit Its kungaba neze amelane nomfutho onjalo. Futhi ngenxa vacuoles contractile aqhubeka elifanayo ingcindezi osmotic nokulinganisela imvelo.

vacuole wokugaya ukudla

Wokugaya ukudla vacuole ninamathele izinto eziyinkimbinkimbi ku elula, ekwazi ukuncela umzimba. Letakhi bamelela imibuso impermanent. Bona Ngalolo ingxenye cytoplasm, lapho izinhlayiyana zokudla. Kungaba kokubili ukudla okuqinile futhi uketshezi. Elibazungezile kwakhiwa odnomembranny isitsha equkethe enzyme hydrolytic. Kuya ngemvelo okuqukethwe medium therein kushintsha kusuka azibukhali ane-alikhali. Lezi izinto eziphila abakhuthele ukusheshisa zamakhemikhali, kodwa hhayi ingxenye imikhiqizo yayo. Ngaphezu kwalokho, ngokusebenzisa udonga vacuoles ukudla engena cytoplasm futhi kugaywe. zesidumbu sakhe undigested labelwe ngokusebenzisa amangqamuzana esikhumba somuntu, noma imfundo ezikhethekile.

Ngakho, kulesi sihloko sabuka lokho vacuole, wahlangana ezihlukahlukene zabo. Kuye izici isakhiwo, ayakwazi ukugcina into, ninamathele kubo, noma esitokisini kanye nezinhlaka zayo.
