Water Abundance and Salinity
Moisture
Humidity
Amount of water vapor increase with temperature.
Absolute humidity
Actual mass of water in certain volume of air.
Relative humidity
Percentage of absolute humidity if the air is saturated with water vapor at the same temperature and pressure.
Water vapour
The rate of water loss from the surface of an organism depends on the difference of vapor pressure between the surface and the air.
Increase in temperature cause higher rate of water vapor.
Water balance in plants
Therophytes
Annual plants that survive via seeds during dry or winter seasons.
Geophytes
Plants with underground stem.
Hemicrytophytes
Plants with buds near the surface of the ground.
Chamaephytes
Plants with renewal buds above the ground.
Phanerophytes
Plants with buds located outside and exposed.
Xerophytes
Plants that grow in dry condition.
Mesophytes
Plants that grow in environment with moderate amount of water .
Hydrophytes
Plants that grow in wet environment.
Halophytes
Plants that grow in salt flats of deserts and salt marshes.
Water environment
Freshwater
Marine water
Brakish water
Water balance in animals
Isotonic environment
the diffusion of water inside and outside of cells via osmosis are at the same rate.
Hypertonic environment
Ability of water molecule to diffuse via osmosis outside cells.
Hypotonic environment
Ability of water molecule to diffuse inside cells via osmosis.
