The stomata are meant for gaseous exchange, however transpiration also occurs when they are open.

Stomata are small pores in the underside of leaves. The primary function is to allow gaseous exchange between the plant's internal tissues and the atmosphere. Oxygen and water vapour (byproducts of photosynthesis) are released from the open stomata into the atmosphere; carbon dioxide present in the atmosphere is allowed to enter the stoma (this is required for photosynthesis.
Stomata are a plants way of exchanging gasses in photosynthesis. The stomata also are resoponsible for transpiration. Most plants have stomata on the under side of the leaf in order to prevent too much water loss. There already is a lot of stomata in leaves but I think you mean to ask "What would happen if the stomata were open all the time?" this would result in mass water loss and cause a plant to wilt.Edited answer:Large number of stomata will increase porocity of the leaves and will facilitate better gaseous exchange and more transpiration.
I had to find the answer to the question too. I think it is to allow gases to diffuse around the cells. It is too important for the gases oxygen when respiring and carbon dioxide when photosynthesis and water during transpiration

Although not necessary, the stomata during gaseous exchange also favour transpiration and provide passage to the microorganisms.
In dicot plants the lower epidermis is frequently ruptured by stomata and thus helps in gaseous exchange and transpiration.
Transpiration is the property that allows a vascular plant to move water from the roots up the stems to the leaves, carrying nutrients with it. This is a very old concept; actually transpiration is an essential evil to the plants. The plants have stomata for gaseous exchange and during this exchange of gases the water vapors also get diffused.
Help in gaseous exchange
gaseous exchange
in day light , they are open, and perform the following three functions 1 Transpiration 2 Gaseous exchange 3 Promotion of ascent of sap***
Gaseous exchange is a natural process, ventilation is a forced process.
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.
