THIS IS BECAUSE
TRANSPIRATION OF GASES AND LOOSING OF WATER FROM UPPER LEAVES STOMATA
THE WAXY LAYER CALLED AS CUTICLE IS PROTECTIVE LAYER ON UPPER SIDE OF LEAF
WHICH HELP TO PROTECT FROM ATMOSPHERE GERMS
THUS, UPPER STOMATA GET MOSTLY OPEN AND CLOSE BUT LOWER MOSTLY CLOSED

Answer:
The number of stomatas present on upper surface of a leaf are comparatively less to prevent excessive water loss through evaporation as it faces direct sunlight.
