A plant grows in a hot, dry habitat. Its leaves are rolled, with stomata on the inside of each roll.
How does this arrangement reduce water loss?
It traps dry air near stomata, increasing water vapour diffusion.
It traps dry air near stomata, reducing water vapour diffusion.
It traps moist air near stomata, reducing water vapour diffusion.
It traps moist air near stomata, increasing water vapour diffusion.
