Which structures allow the flow of carbon dioxide into a plant?

The correct answer is: stomata

Stomata are microscopic openings-pores located on the surface of a leaf (sometimes on stems) necessary for gas exchange. The opening and closing of pores are regulated processes thanks to guard cells that surround stomata. Stomata allow carbon dioxide take in, for photosynthesis but they also help in reducing the water loss by closing when conditions are hot or dry.
