Do a search on "stomata" and read about the function of stomata on plants.

opined:

Do plants actually absorb any water through their leaves? I thought
this is what roots were for.

I know people that like to spritz or spray their plants' leaves with
water. Is there really any point to this, other than cleaning the
leaves?

Thanks for your help.
