TRANSPIRATION Flashcards
1
Q
where is water absorped?
A
water is absorped through root hair cells
2
Q
how does water move by osmosis
A
SOIL -> ROOT HAIR CELL -> CORTEX CELLS -> XYLEM -> LEAF
3
Q
how does the leaf transpire?
A
WATER EVAPORATES IN MESOPHYLL AND EXISTS THROUGH STOMATA
4
Q
what is transpiration?
A
evaporation of water and exit from the stomata of plant leaves
5
Q
how does light increase transpiration rate?
A
TRIGGERS STOMATA TO OPEN
6
Q
how does temprature increase transpiration rate?
A
MORE KINETIC ENERGY, CAUSING EVAPORATION
7
Q
how does wind speed increase transpiration rate?
A
INCREASE IN WINDS REMOVE WATER FROM LEAFS SURFACE, MAINTAINING LARGE DIFFUSION GRADIENT
8
Q
how does humidity increase transpiration rate
A
DECREASE IN HUMIDITY CREATING HIGHER DIFFUSION GRADIENT
