transpiration and stomata Flashcards
1
Q
what are the 4 main things that effect transpiration rate
A
light intensity
temperature
air flow
humidity
2
Q
how does light intensity effect transpiration rate
A
the brighter the light the greater transpiration rate
photosynthesis cant happen in the dark so they need to be open to co2
3
Q
how does temperature effect transpiration rate
A
the warmer it is the faster transpiration happens
when its warm particles have more energy to diffuse out of the stomata
4
Q
how does air flow effect transpiration rate
A
the better the air flow around a leaf the better the transpiration
5
Q
how does humidity effect transpiration rate
A
the drier the air around the leaf the faster transpiration happens
6
Q
how can you estimate the rate of transpiration
A
by measuring the uptake of water by a plant
