Considering that leaf stomata have the conflicting functions of allowing gaseous carbon dioxide into the leaf, yet preserving the plant's supply of water, which of the following is NOT reasonable?
( ) Tree leaves that orient flat and present the top side to the sun would have most of their stomata on the bottom of the leaf
( ) A submerged-water plant would have no stomata
( ) Corn, oats, rice, and wheat (all monocots) have relatively upright blades with sunlight hitting both sides and would have stomata distributed fairly evenly on both sides
( ) Leaves of plants in dry areas will have more stomata than leaves of plants in humid areas
( ) Plants in arid environments open their stomata at night when temperatures are cooler and evaporation occurs less
Leaves of plants in dry areas will have more stomata than leaves of plants in humid areas
