(2 points) (2 pts) Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves. 0 pts) Plants in hot, arid climates would have more stomata because they would need to release heat from the leaves to prevent dehydration. (0 pts) Plants in tropical climates would have fewer stomata because they would need to prevent the absorption of too much water from the atmosphere. (0 pts) Plants in tropical climates would have more stomata because they would need to absorb more water from the air than plants in arid climates. 0 /2 points 16.
