CO2 would have a very difficult time entering the plant and the plant could not make food or construction materials as all sugars made by the plant are based on the carbon in carbon dioxide.
the stomata are used to exchange water and air on the leaf surface.
plants for sake of adapation on upper side of leaf have less number of stomata for reducing the rate of transpiration compare with lowerside
the stomata will get blocked
On a dorsi-ventral leaf most of the stomata are found on the lower side of the leaf, that remains away from sunlight. On an iso-bilateral leaf stomata are present on both the sides, upper as well as lower.
Gases enter and exit a leaf through stomata. These are openings in the epidermis which are regulated by guard cells. Guard cells decide which gases can go in and out. The gas that goes in is carbon dioxide and the gas that goes out it oxygen.
Stomata
duckweeds does not have stem but only roots.
stomata is present on a leaf's lower surface. but in plants that float on water, stomata is present on a leaf's upper surface, and the lower surface is protected by a coating of wax.

Stomata....
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.

Stomata
Yes they do! All leaves have stomata, but the lotus's stomata are on the top of the leaf, not the bottom.
