There are cells called guard cells on the tiny pores (stomata) on the underside of a leaf. According to the status of the gases inside the leaf cells, and the outside conditions, the guard cells allow air into the pores. This brings in carbon dioxide and releases oxygen, but also releases water vapor. This transpiration process can be used to cool the leaf as needed.
What else can I help you with?
How does lower epidermis adapt to do it job in the leaf?
In dicot plants the lower epidermis is frequently ruptured by stomata and thus helps in gaseous exchange and transpiration.
How does gaseous exchange with the surrounding occur in land plants?
It is because Co2(carbon dioxide) is transferred to the plant and the plant makes the Co2 Oxygen.
What is the life process that the pores in the leaves are responsible for?
Gaseous exchange
What is the function of water in a leaf?
Water in a leaf is crucial for photosynthesis, where it serves as a medium to transport nutrients and minerals throughout the leaf. Additionally, water helps maintain the turgidity of the leaf cells, providing structural support and enabling gas exchange through stomata.
What is the function of stomates in a plant?
Gaseous exchange and evaporation of water vapour
Where does gaseous exchange take place in a leaf'?
stomata
What allow gaseous exchange between leaf and atmosphere?
Stomata on the underside of the leaf control the passage of gases into and out of the leaf.
By what mechanism does gaseous exchange occur?
simple diffusion
What is the purpose of the spongy layer in a plant leaf?
The spongy layer in a plant leaf facilitate better gaseous exchange for photosynthesis and respiration.
What negative impact occurs when guard cells closing on the plant leaf?
The gaseous exchange is hampered.
How does gas exchange occur?
Gaseous exchange takes place when the volume of the chest cavity is increased or decreased.
What is the name for exchange of gas in the lungs?
gaseous exchange
How does the leaf gaseous exchange take place?
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.
Why are the spaces in the spongy mesophyll important?
I had to find the answer to the question too. I think it is to allow gases to diffuse around the cells. It is too important for the gases oxygen when respiring and carbon dioxide when photosynthesis and water during transpiration
How does lower epidermis adapt to do it job in the leaf?
In dicot plants the lower epidermis is frequently ruptured by stomata and thus helps in gaseous exchange and transpiration.
What is the difference between ventilation and gaseous exchange?
Gaseous exchange is a natural process, ventilation is a forced process.
Where is the site for gaseous exchange?
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.
