Q

OSMOSIA

A
  • kontzentrazio desberdineko 2 disoluzio
  • mintz erdi iragazkor baten bitartez (solutu molek soilik) mintz plasmatiko
  • jario osmotikoa (hipotonikotik hipertonikora)
  • kontzentrazioak berdintzeko (ISOTONIKO) joera

Q

INGURUNE OSMOTIKOAK

A
  1. isotoniko : berdinduta = funtzionaltasun normal
  2. hipotoniko: ur gehio sartu = hanpadura/turgentzia= LISIA hemolisia
  3. hipertonikoa: ur gehio atera = zimurtu = LISIA plasmolisia

Q

SOL ETA GEL

A

sol: likido/ jariakor= ur kantitate handiagoa
gel: gelatinakor = ur kant txikiago (solutu molek artean ur molek harrapatuta)
1. endoplasma : sol
2. ektoplasma: gel zelularen zitosola 2 egoeratan = mugimendua
