- vapor pressure deficit
- difference between WVP and SWVP at a particular temperature
- what does high VPD indicate?
- water vapor content in air is below saturation, evaporative water loss by organisms is higher
- gradient of water
- water moves down concentration gradient
- where is water more concentrated?
- in freshwater
- aquatic organisms
- aqueous solution bounded by a selectively permeable membrane floating in another aqueous solution
- osmosis
- diffusion of water through a semipermeable membrane
- water regulation of land animals...
- -drinking -food -absorbed by air -evaporation -secretion/excretion
- water can be gained via metabolism through what?
- oxidation of glucose -C6H12O6 = 6CO2 + 6H20
- metabolic water
- water released during cellular respiration
- animals in dry climates water loss?
- lose less water
- water regulation on land plants
- -roots -air -transpiration -secretion (nectar)
- water conservation by plants and animals?
- -waterproof covering -concentrated urine/feces -condensing water vapor in breath -behavorial changes -thick leaves -few stomata -preiodic dormancy
