Biology 3.1.3 Factors effecting transpiration
Cards in this deck (7)
- 1How does the number of leaves effect the rate of transpiration?More leaves = more transpiration as more water vapour is being lost at one time due to more leaves
- 2How does the number/size of stomata effect the rate of transpiration?More and bigger stomata increase the rate of transpiration
- 3How does the light intensity effect the rate of transpiration?Increased light intensity results in more open stomata, so more water vapour can diffuse out of the leaf
- 4How does temperature effect the rate of transpiration?Higher temperatures result in increased transpiration as the molecules have more kinetic energy so evaporate from the mesophyll cells more, increasing water potential gradient, making water diffuse out faster
- 5What is humidity?The amount of water vapour in the air compared to the total concentration of water that the air can hold
- 6How does humidity effect the rate of transpiration?Lowered humidity results in faster transpiration as if there is less water vapour in the air, there is a greater water potential gradient between the air and the leaf
- 7How does the amount of wind effect the rate of transpiration?The windier the conditions, the more transpiration as the wind will blow away the water left on the surface of the leaf, increasing the water potential gradient
