transpiration Flashcards
_______ ______ is where photosynthesis takes place?
palisade mesophyll is where photosynthesis takes place
_________ is the evaporation of water vapour from the surface of a plant?
transpiration is the evaporation of water vapour from the surface of a plant
transpiration starts from ________ of water from cells inside leaf?
transpiration starts from evaporation of water from cells inside leaf
water vapour diffuses through air spaces in spongy mesophyll and out of leaf through _____?
water vapour diffuses through air spaces in spongy mesophyll and out of leaf through stomata
water passes through ____ into leaf to replace lost water?
water passes through xylem into leaf to replace lost water
finally, water is drawn into ____ ____ cells and up into xylem vessels to leaf?
finally, water is drawn into root hair cells and up to xylem vessels to leaf
transpiration brings in water into leaf, which is required for ______?
transpiration brings in water to leaf, which is required for photosynthesis
transpiration stream transports dissolved ______ ___ to plant?
transpiration stream transports dissolved mineral ions to plant
how does an increase in temperature affect rate of transpiration?
increased temperature increases rate of transpiration
why does increase in temperature increase rate of transpiration?
evaporation is faster at higher temp
how do dry conditions affect rate of transpiration?
rate is higher under dry conditions
why is rate of transpiration higher under drier conditions?
because wind removes any water vapour, allowing more water to evaporate
how does an increase in light intensity affect rate of transpiration?
increase in light intensity increases rate of transpiration
why does an increase in light intensity increase rate of transpiration?
because stomata opens up for photosynthesis
stomata are surrounded by 2 ____ __?
stomata are surrounded by 2 guard cells
