Without stomata, plants could not exchange gases or perform proper transpiration. Photosynthesis, respiration and cooling would be affected. Water transport through transpiration pull would reduce, disturbing growth, food preparation and overall survival of the plant.
What do you think will happen if there were no stomata in the epidermis of the stem or leaves?

If stomata were absent, plants would face serious problems in gaseous exchange and transpiration. Carbon dioxide could not enter properly for photosynthesis and oxygen release would decrease. Transpiration pull responsible for upward water movement would also reduce. Plants would overheat, transport less water and minerals and fail to perform important life processes efficiently for healthy growth.
