Oxygen leaves the leaf because it is actually useless to the plant. We breathe in oxygen, because we need it to survive, and we breathe out carbon monoxide, which is contained in our cells but is harmful to us. Plants work together with us - as we breathe out the carbon monoxide, they take it in because they need it, and in return they let out oxygen, which we need.
Stomata allow carbon dioxide to enter the leaf for photosynthesis, while also allowing oxygen and water vapor to exit the leaf through transpiration.
Gas exchange in leaves occurs through tiny openings called stomata. During photosynthesis, the stomata open to allow carbon dioxide to enter the leaf and oxygen to exit. During respiration, the opposite occurs, with the stomata opening to release carbon dioxide and take in oxygen.
Air spaces in the spongy layer of a leaf facilitate gas exchange by allowing for the movement of oxygen and carbon dioxide between the leaf cells and the external environment. This helps in photosynthesis by providing a pathway for carbon dioxide to reach the chloroplasts and for oxygen to exit the leaf during respiration.
Leaf gaseous exchange occurs through tiny pores called stomata on the surface of leaves. During photosynthesis, carbon dioxide enters the leaf through the stomata, while oxygen and water vapor exit the leaf through the same pores. This exchange of gases is crucial for the process of photosynthesis and respiration in plants.
The broad, flat shape of a plant's leaf maximizes the surface area available for absorbing sunlight. The presence of chloroplasts containing chlorophyll within the leaf cells allows for the absorption of light energy needed for photosynthesis. The presence of stomata on the leaf surface enables gas exchange, allowing carbon dioxide to enter for photosynthesis and oxygen to exit as a waste product.
The leaf has a wide range of pores which allow Carbon Dioxide to enter and Oxygen to exit.
Stomata allow carbon dioxide to enter the leaf for photosynthesis, while also allowing oxygen and water vapor to exit the leaf through transpiration.

A stomata, which allows for the exchange of oxygen to exit and carbon dioxide to enter.
Carbon dioxide enters the leaf through small openings called stomata. Inside the leaf, carbon dioxide is used in photosynthesis to produce oxygen and glucose. Oxygen and excess water exit the leaf through the stomata as byproducts of photosynthesis and transpiration, respectively.
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.
The exchange of gases in a leaf primarily occurs in the mesophyll cells, which are located in the interior layers of the leaf. The stomata, small openings on the surface of the leaf, also play a crucial role in gas exchange by allowing carbon dioxide to enter and oxygen to exit the leaf.
An air molecule can be drawn into a leaf through tiny openings called stomata. Stomata open and close to regulate gas exchange, allowing carbon dioxide to enter and oxygen to exit the leaf. This process is crucial for the leaf's photosynthesis and overall functioning.
