Yintoni na le vacuole: iintlobo kunye neempawu zezakhiwo

Iiseli izityalo kunye nezilwanyana ziqulathe iintlobo zezakhiwo ukuba enze imisebenzi yabo ebalulekileyo. Enye yazo vacuole. Phakathi kwabo, banalo umahluko omkhulu. Kweli nqaku uza kufunda oko vacuole yaye kutheni ukuze eziphilayo.

isakhiwo cell esisigxina

vacuoles ebizwa odnomembrannye organelles, iiseli izityalo kunye nezilwanyana. Ezinye zazo izakhiwo ezisisigxina, ngoxa abanye kuvela njengoko kokokunyanzelwa ezisebenzayo. Kuxhomekeka isakhiwo ethile kwezi organelles ayakwazi ukugcina izondlo, ahlukana yaye enze nowolawulo.

iintlobo zezakhiwo

Kukho iindidi ezintathu vacuoles. Xa iiseli lwezityalo contractile esiswini. Bona ukulawula uxinzelelo osmotic, abakhutshwa ngaphandle iintsalela undigested aze enze umsebenzi secretory. Kodwa ke izityalo amatanki ezinkulu eziqulathe amanzi, nto leyo zonke ngoku zichithakala nje impahla iseli.

Vacuoles ezitokisini plant

Xa iiseli isityalo esitsha, ezi zakhiwo unokuhlala kakhulu kwako konke okuqulathwe embilwini. Ke kulula ukuba uchaze. Eneneni, umzimba owandayo kakhulu arhente backup kuphuhliso. Yintoni na vacuole kweeseli zezityalo? Oku iitanki odnomembrannye enkulu iseli incindi. Le yokugqibela i amanzi kunye carbohydrate lichithakale kunye iintsalela izinto neorganichskih. Ubume esiseleni incindi nayo iquka iintlobo imveliso metabolic. Kusenokuba sezakhi, tannins. Kukho kwakhona zombala ezenza umbala iindawo ezahlukeneyo kwisityalo. Ngoko ke, lo vacuole kwisisele yezityalo udlala indima yokuba "indawo yokugcina".

contractile vacuole

Ubume vacuole, leyo ezisebenza umsebenzi ezilawulayo, yahlukile kakhulu. Uninzi lwezi zakhiwo ezifumaneka iiseli amatsha kunye protozoans zaselwandle. Yintoni na vacuole, elawula turgor yeseli? Bamele sinomoya izwekazi, nto leyo ifumaneka ehlabathini womnatha tubular. Le indlela zothutho ngenxa ulwelo. tubules Ngokutsho ulwelo kwemfuneko eza kuqala ukusuka kukho icytoplasm ukuya vacuole, kodwa ngenxa yokuba sele zoke ngaphandle.

u tlhele Apho fluid kwemfuneko kwiseli yaye kutheni kufuneka zisuswe? Zonke umcimbi imithetho physics. Ngokutsho kwabo, intshukumo lwenzeka ukusuka kummandla we ingqalelo ngaphezulu yesimo. Njengoko iityuwa kwi-bume amanzi amaninzi uqala ukuba kuthunyelwa kule seli. unit wayo umphezulu awukwazi nje ukumelana naloo mpembelelo. Kwaye ngenxa vacuoles contractile igcinwe umgangatho ofanayo yoxinzelelo osmotic kwaye siyinonophele indalo.

vacuole sokugaya

Sokugaya vacuole ninamathele ezintsonkothileyo izinto zibe lula, ezinako ukukulumkisela ukufunxa ngumzimba. Ezi zithinteli zizinto ezikhoyo impermanent. Baya kuthi ngaloo nxalenye kukho icytoplasm, apho amasuntswana ukutya. Kunokuba zombini eziqinileyo kunye ulwelo. Around kubo wabumba odnomembranny igutyana equlethe enzyme hydrolytic. Kuxhomekeka kuhlobo eliphakathi kokuqulathwe uziguqule asidi obrak. Ezi izinto eziphilayo esebenzayo isantya ekudibaneni kwemichiza, kodwa inxalenye imveliso yawo. Ngaphezu koko, udonga ukutya vacuoles engena kukho icytoplasm kunye kwetyiswe. amathambo akhe undigested eyabelwe iiseli ulusu, okanye ngemfundo eneemfuno ezizodwa.

Ngoko ke, kweli nqaku siza wajonga leswi vacuole, bahlangana kunye neentlobo zabo. Kuxhomekeka iimpawu isakhiwo, ayakwazi ukugcina into, ninamathele kuwo, nokuba ubengekho na iseli nezakhiwo zawo.
