How Oxygen Is Transferred in Plants

Oxygen produced in the plant by splitting the water molecule. Oxygen is a by product of photosynthesis. In the plant oxygen flows out of the stoma. Oxygen is also released through roots. Plants need oxygen for photosynthesis. Plants have adapted to exchange gas such as lenticels. Plants usually don’t use gas exchange at night because they will be wasting c02.

Roots are designed to transport water and minerals to the plant. However, roots can also release oxygen. Roots also gather oxygen from the soil. Roots have a large surface area to gather more water. Which means that the oxygen is dispersed over a large area. The oxygen is returned to the soil. It can also flow to other places in the form of runoff.

Leaves have a wide surface area in order to capture more carbon dioxide. It also helps in the release of oxygen. Leaves are covered with stomas which release oxygen. The stomas work by opening up to let the gases in and out. The cell that controls the stoma is the guard cell. Pair of guard cells gather water and open the stoma. When the guard cells lose water the stoma closes. Oxygen flows out of the stoma when it is open. Also, lenticels are found in the bark and they exchange oxygen and other gases.
