How are leaves adapted for gas exchange?
Leaves are adapted for gas exchange through a process called photosynthesis. During photosynthesis, leaves absorb carbon dioxide (CO2) from the air and release oxygen (O2) and water vapor (H2O) back into the air. This gas exchange occurs through tiny pores on the surface of leaves called stomata.
Stomata are surrounded by specialized cells called guard cells, which control their opening and closing. When the plant needs to take in carbon dioxide for photosynthesis, the guard cells open the stomata to allow the gas to diffuse into the leaf. At the same time, water vapor and oxygen are released through the same pores.
Leaves are also adapted for gas exchange through their thin, flat shape, which increases their surface area and allows for more efficient gas exchange. Additionally, the internal structure of leaves, which includes a network of veins and cells that transport water and nutrients, helps to maintain the balance of gases needed for photosynthesis. Overall, the adaptations of leaves enable efficient gas exchange and support the process of photosynthesis, which is essential for the survival of plants and the production of oxygen in the atmosphere.

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and glucose (C6H12O6). During photosynthesis, leaves absorb carbon dioxide through stomata, and release oxygen and water vapor back into the air.
Guard cells are specialized cells that surround stomata and control their opening and closing. When the plant needs to take in carbon dioxide for photosynthesis, the guard cells open the stomata to allow the gas to diffuse into the leaf. At the same time, water vapor and oxygen are released through the same pores.
Gas exchange is important for plant survival because it is necessary for photosynthesis, the process by which plants produce their own food and release oxygen into the atmosphere. Without efficient gas exchange, plants would not be able to absorb the carbon dioxide needed for photosynthesis or release the oxygen produced during this process.
