effect of environmental conditions on transpiration Flashcards
1
Q
temperature
A
water will evaporate quickly as the water molecules have more kinetic energy
2
Q
humidity
A
humid air - water vapour = smaller conc gradient so transpiration slows down
3
Q
wind speed
A
moving air - water vapour blown away from leaf - speeds up transpiration
4
Q
transpiration .. as wind speed ..
A
transpiration increases as wind speed increases
5
Q
transpiration .. as humidity ..
A
transpiration increases as humidity decreases
6
Q
transpiration .. as temperature ..
A
transpiration increase as temp increases
7
Q
light intensity does NOT affect
A
evaporation
8
Q
light intensity
A
in daylight stomata leaves are open to supply CO2 for photosynthesis
allows more water to diffuse out leaves into atmosphere
