Contractile vacuole umsebenzi ingenisiwe

Eli nqaku wazisa umfundi isakhiwo eziphilayo elula - ezizezi, igxininisa isakhiwo vacuole contractile ukwenza excretory (hayi kuphela) umsebenzi, uya kuthetha ngayo intsingiselo ilula kwaye ichaza neendlela ubukho babo bume.

Contractile vacuole. ukuba nombono

Vacuole (ukusuka vacuole French, ukusuka vacuus Latin ilizwi -. Engenanto), angabi nemingxuma ezincinane ungqukuva kwizisele izityalo nezilwanyana okanye kwiseli enye. Contractile vacuole ngakumbi eqhelekileyo phakathi eziphilayo elula ezihlala emanzini amatsha, umzekelo, phakathi protists ezifana amoeba proteus, Paramecium caudatum, apho wafumana igama layo lokuqala ukususela imilo lomzimba, ezifana imilo yomphantsi izihlangu. Ukongeza kwezi elula, izakhiwo twatse awafunyanwayo iiseli iziponji ezahlukeneyo yamanzi, ziphantsi spongillidae usapho.

Ubume vacuole contractile. iimpawu zayo

Contractile vacuole i organelles inwebu, nto leyo elenza ejection kolwelo engaphezulu evela kukho icytoplasm. Indawo nesakhiwo le yunithi yahluka xa eziphilayo ezahlukeneyo. I ezintsonkothileyo bubble-okanye tubular vacuoles ekuthiwa Spong, ulwelo ongena vacuole contractile. Ngenxa ukusebenza rhoqo kwenkqubo igcinwe esitalini cell umthamo. Xa elibangela babe vacuoles contractile, leyo zenza unit elawula uxinzelelo osmotic kwaye ukhonza ukuba osenyameni evela iimveliso ukubola komzimba. nje umzimba siquka iseli enye kuphela, nto leyo, inika yonke imisebenzi eyimfuneko yobomi. Abameli ezifana Paramecium caudatum, Amoeba Proteus, enye kwiseli enye le subkingdoms ilifa zonke iipropati ezimele.

Indima eziphilayo elula

Cage owenza yonke imisebenzi ebalulekileyo: ukhetho, yokuphefumla, ukuba nochuku, intshukumo, ukuzala, futhi umzimba. Elibangela ukuba ikuyo. Inani elikhulu kweentlobo kuhlala elwandle kunye fresh amanzi, abaninzi kulo umhlaba ufumile ukuze kuchaphazela ubomi bezityalo kwi imizimba yezilwanyana multicellular kunye nabantu. Kwindalo, esenza nje indima yococeko, njengoko inxaxheba ukuhamba kwezinto, ukuba ukutya kwizilwanyana ezininzi.

Contractile vacuole e Amoeba Proteus

Amoeba Proteus - ummeli rhizomes eklasini, akunjalo, ngokwahlukileyo kwamanye amalungu omzimba ifomu ngokusisigxina. Ukufudukela elandelayo nge prolegs. Ngoku makhe ukujamelana nabo, yintoni na umsebenzi vacuole contractile kwi amoebae. Lo mmiselo level xi osmotic ngaphakathi cell yayo. Yena ke Amoeba Proteus nga abunjwe ngayo nayiphi na inxalenye kwiseli. Esebenzisa inwebu engaphandle amanzi kwindalo lungena ngokukhululekileyo osmotically. Uyondelelwano lwee- kwesinyibilikisi esiseleni amoeba ngaphezulu kokusingqongileyo. Ngoko ke, umahluko xi ngaphakathi iiseli cebetshu nangaphaya. imisebenzi Contractile vacuole kwi amoeba - uhlobo isixhobo sokufunxa ukuba ovelisa amanzi agqithisileyo kwiseli lenyama. Nokuchithela bume Amoeba proteus ulwelo aqokelelwe ngayo kuyo nayiphi na inxalenye phezu komzimba.

Loo umsebenzi kwemigaqo vacuole contractile yamkelekile ukuba eziphilayo elula ezihlala emanzini ahlaziyekileyo. Kwiintlobo olwaye lwamfimfitha kweelwandle phila kwindawo apho uxinzelelo osmotic ingaphezulu emanzini aphilileyo, ezi zixhobo bakudala zancitshiswa okanye kunqabile kakhulu zidla bengekho. Around vacuoles contractile kwi eziphilayo kakhulu elula mitochondria bagxila ehambisa amandla ukwenza umsebenzi osmotic.

Ngaphandle osmoregulatory ezisebenza umsebenzi ebalulekileyo yokuphefumla, ngenxa kucocwa enikezela amanzi engenayo lichithakale oksijini. Yintoni na ke umsebenzi vacuole contractile? ukwenza nje umsebenzi excretory, ezizezi kunye amanzi asuka iimveliso pathways kwindawo yazo.

osmoregulation yokukhetha Breath nesabo ciliates

Umzimba wambu nje kwiqokobhe ashinyeneyo, nto leyo iba imilo rhoqo. Sidla iintsholongwane, kwakunye nezityalo, kuquka ezinye lenyama. Ciliates ephilayo sinzima ngaphezu koko kobume amoeba. Esiseleni, ngaphambili kunye nezihlangu angasemva ke vacuoles ezimbini contractile. Kule yunithi itanki distinguishable kunye tubules ezininzi ezincinane. Contractile vacuole rhoqo, ngenxa kwesi sakhiwo (microtubule), kwindawo esisigxina kwiseli.

Umsebenzi iphambili vacuoles contractile kwi kubomi ummeli elula - osmoregulation, njengoko amaxolo asuswa iiseli amanzi agqithisileyo, apho ungena iseli ngenxa kucocwa. Okokuqala, kukho iindumbisa imiphantsi abaziintloko, ngoko ke amanzi Impontshelwa kuzo kwitanki ekhethekileyo. Le dama lifinyele, abazahlulayo ukusuka kwisiphumo se Kusungulwe iyayondela amanzi alahlwayo. Esiseleni, ciliates ezi vacuoles contractile ezimbini, mvisiswano leyo, kwelinye icala, benza inkcaso. Ngenxa ukusebenza izixhobo ezimbini ezifana wasinika eqhubekayo. Ukongeza, amanzi lusoloko kuthunyelwa nge nemisebenzi vacuoles contractile. Bona zixinaniswe khosi kunye nokuhla frequency kuxhomekeke lobushushu kuma kulo.

Ngenxa yoko, bushushu (18 - 20 degrees Celsius), nezihlandlo izishunqulelo of vacuoles, njengako imizuzwana ezithile 10-15. Yaye xa sicinga ngokuba izihlangu zendalo zokuhlala na amanzi ngamanzi kunye nobukho kuwo yokuba ezibolayo emi, iqondo lobushushu eliphakathi kwi izidanga ezininzi kuyahlukana nedlela ngexesha lonyaka kwaye ngoko kangaphi izishunqulelo uyakwazi ukufikelela imizuzwana 20-25. iyure enye contractile vacuole kokuphilayo elula Ukuphosa ekwaziyo leseli isixa amanzi. ngokobukhulu bayo. Bandisa izondlo undigested ukutya, iimveliso isiphelo metabolic, nazo ibhaqwe oksijini nitrogen.

lenyama unyango Wastewater

Ukusebenza ejikelezayo elula izinto ngokwendalo kubaluleke kakhulu. Xa amadama ngenxa ekuhleni amdaka, zithembise nakancinane xa iintsholongwane ezininzi. Ngenxa yoko, kukho lenyama awohlukeneyo asetyenziswa ukutya kunye nale ntsholongwane, yaye ngaloo ndlela negalelo zendalo okugcina amanzi zokucoca.

isiphelo

Phezu kwako okulula kula elilodwa olunye-, umzimba yayo libunjwa iseli enye, kodwa wenza nemisebenzi yonke ephilayo, emangalisayo malilungiselelwe bume. Singaba ngisho kubonwa kwi isakhiwo vacuole contractile. Ukuza kuthi ga ngoku, sele kwaba kubaluleke kakhulu kwi nohlobo elula kwaye ukuthatha kwabo inxaxheba kumjikelo lomba.
