Humidity
Increased humidity decreases transpiration. This is because high water content outside the leaf will mean there is little difference in concentration, so the water will not be able to move- as it naturally does- from an area of high concontrartion to an area of low concentration.
Wind speed
Increased wind speed will increase transpiration. Because if the wind blows away the water vapour being produced their will be a greater difference in water concentration, meaning water will be able to continue leaving the leaf.
Temperature
Increased temperature increases transpiration, as increased heat makes evaporating easyer.
Light intensity
Increased light intensity increases transpiration, as more heat is absorbed by the leaf meaning more water will be evaporated, also there is more photosynthesis meaning more water is being transported through the leaf (so more will need to leave the leaf.)
when you say "water moves from an area of low concentration to high concentration" when discussing the effects of humidity, possibly make it clearer that you are referring to the concentration of other substances, not of water itself (which moves down a concentration of water gradient)
ReplyDeleteThink she just got them the wrong way round
DeleteAlso im in your science set (5E)
Delete*Concentration
ReplyDelete*easier
Light causes stomata to open in the leaves allowing water to escape also rather than saying that evaporating is easier it might be better to say that the rate of evaporation is increased with increased temperatures
