Water ralations Flashcards
Water regulation by plants
to gain water:
Grow or redirect roots
To not loose water:
Avoid droughts (ephemerals- only grow during rainy season and die when drought starts)
Reduce leaves to avoid evaporation
Live where there’s more water (under ground and nurse plants)
Waxy and though leaves
Animal adaptation
Increase uptake:
Drinking water(if you have acces)
Use fog
Metabolic water (glucose oxidation)
Osmoregulation
Regulation of solute balance and the Gail/loss of water
Osmosis
Water moves from areas of higher concentrationn to lower areas of concentration
isosmotic organisms
Body fluid of organisms contains same concetration of water and solutes as enviroments
HypOsmotic organimss
Body fluids contain higher concentrations of water (and lower in solutes) than environment (marine fish)
HypErosmotic organims
Body fluids of organims contains lower concetration of water(and higher solutes) than enviroment (freshwater fish)
