Why are the pores that lose water found on the bottom surface of the leaf?

Warmth and wind currents take moisture away from leaves.





Most of the pores that lose water are found on the bottom surface of the leaves. Why is this?|||pores = stomata


if there we reversed the way the current leaf is now, then less photosynthesis will occur as guard cells and other cells which are on the bottom of the leaf has less chloroplast. so, if we turn it upside down, the leaf would have it%26#039;s side which has the most chloroplast away from the sun, which would cause less photosynthesis and more water will be lost as the sun will allow faster evaporation and plants would die faster.|||if the pores were on top of the leaf, when it rained, the tree would essentially drown. the tree needs to breath in a similar way that humans do, so if when it rained their pores were blocked by water, the tree would not be able to bring in the nescesary amounts of co2. even though the tree would be able to survive this, most likely, evolution benefits the best of a species, and since pores below the leaves are superior to pores ontop, the trees have evolved to all have pores below their leaves.
