Transpiration Flashcards
What are the 4 main factors that affect transpiration
Humidity
Wind
Light intensity
Temperature
How does light intensity affect transpiration
The brighter the light the greater the transpiration rate
More of
Photosynthesis, co2, stomata open more, more evaporation
How does wind affect transpiration
Faster transpiration rate
More:
Air movement/dryer air, water removed from surface of leaves, more evaporation
How does temperature (heat) affect transpiration
Faster transpiration rate \
More sun
More kinetic energy in water
How does humidity affect transpiration
more humidity/moisture in the air Less difference between water ion air and leaf Less water removed from surface of leaf Less evaporation Slower transpiration
What is transpiration
The loss of water from a plant, from the roots to the leaves
What is transpiration caused by
Evaporation and diffusion of water from a plants surface
Evaporation causes a shortage of water in the leaf, where is more water drawn up from
The rest of the plant, through the xylem
What is the transpiration stream
The constant flow of water through a plant
