Transpiration

HideShow resource information
An increase in transpiration could be caused by?
More air movement
1 of 9
A decrease in transpiration could be caused by?
Lower temperatures
2 of 9
Xerophytic plants are......?
plants that are adapted to live in areas where their water loss due to transpiration exceeds their water uptake.
3 of 9
An adaption of a Xerophyte could be?
Rolled up leaves
4 of 9
How does the stomata in grooves help to reduce transpiration?
Traps moist air next to the leaf and therefore reduces the water potential gradient.
5 of 9
An example of a plant that has stomata in grooves is a.......?
Pine Tree
6 of 9
How does a higher temperature increase transpiration rate?
Increases the speed of movement of water molecules which increases the rate of evaporation of water therefore evaporation happens more quickly so the rate of transpiration increases.
7 of 9
What is the role of stomata in a plant?
Allow gases such as carbon dioxide, water vapor and oxygen to move rapidly into and out of the leaf. (gas exchange)
8 of 9
Limiting factors of photosynthesis are?
Water, light, temperature and carbon dioxide levels
