How does gas exchange occur in a leaf
WebJul 7, 2024 · The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night. How many alveoli are in lungs? Web13.4 Summary. Gas exchange. is the biological process through which gases are transferred across cell membranes to either enter or leave the blood. Gas exchange takes place continuously between the blood and cells throughout the body, and also between the blood and the air inside the lungs. Gas exchange in the lungs takes place in.
