Statement A: Leaves of dicots are dorsiventral leaves. 

Statement B: A dicot leaf has more number of stomata on the adaxial side than abaxial side. 

Dicot leaves are dorsiventral leaves because the adaxial side or ventral side is different from abaxial side or dorsal side. Dorsal side has more stomata in the epidermis and has spongy mesophyll. Ventral side has less or no stomata and it has palisade mesophyll.
