Kurerutsa Mutauro[chinja | edit source]

  • Permeable zvinoreva chiro chinobvinina.
  • Semipermeable or selective permeability zvinotaura chiro chinosarura mheu dzinokwanisa kudarika pakubvinina, asi chiro ichi chichidzivisa dzimwe mheu kudarika. Nokumwe kutauro kunopfupisa tinokwanisa kuti nhengodzivo inosarura zvinobvinina kureva iyo selective permeability.
  • Mamwe mashoko anokwanisa kushanda kureva membranne ndeanoti: nhengopfunha kana mudzivo wenhengo. Shoko rokuti mudzivo (boundary) rinoreva pamuganhu panoperera nhengo, mutumbi kana kana chinhu chiri kucherechedzwa. Saka apa zvoreva kuti membrane inenge iri muganhu wenhengo. imwe kana muganhu unoganhura nhengo kubva kune dzimwe nhengo. Pahuwandu kunenge kuchinzi nhengodzivo zvakare.
