Question

Stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen that take place during what process?

Answer 1

photosynthesis

For photosynthesis, stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen. Stomata are flanked by guard cells that swell or shrink by taking in or losing water through osmosis. When they do, they open or close the stomata.
