How does oxygen exit a leaf?
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.
How carbon dioxide enter the leaves?
stomata
Describe the pathway followed by a water molecule from the time it enters a plant root to the time it enters a plant root to the time it escapes into the atmosphere from a leaf?
A water molecule enters a plant root through specialized cells called root hairs and moves up through the xylem tissue, driven by capillary action and transpiration pull. It then flows through the stem and into the leaf where it exits the plant through tiny pores called stomata as water vapor, a process known as transpiration.
State the function of the structures called stomata that are present in leaf epidermis?
The leaf surface has many tiny apertures called stomata. During respiration oxygen from the atmosphere diffuses into the stomata and then into the cells of the leaf. When carbon dioxide concentration in the cells increases, the stomata opens and releases carbon dioxide into the atmosphere.
A specific molecule that diffuses into the blood of the lung?
Oxygen is a specific molecule that diffuses into the blood in the lungs during the process of respiration. This exchange occurs in the alveoli, where oxygen moves from the air sacs into the bloodstream to be transported to tissues in the body.
What happens when the stomatas of a plant are facing the sun?
The guard cells in the stomata will swell and it will cause the pores to be at its widest and CO2 diffuses into the leaf and into the cells and it will be used for photosynthesis. It will also diffuse water vapour from the leaf.
How does an air molecule get sucked into a 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.
In plant cell where diffusion occurs?
Gas exchange for photosynthesis - CO2 from the air diffuses into the leaf, and 02 diffuses out of the leaf into the air
How does carbon dioxide get into the leaf?
through the pores in the stomata of the leaf
What is a specific molecule that diffuses into the blood at the lungs?
oxygen
How does Oxygen and carbon dioxide diffuse in and out of a leaf through the?
In a leaf, oxygen diffuses out through small openings called stomata on the underside of the leaf, while carbon dioxide diffuses in through the same stomata. This exchange of gases occurs due to differences in concentration and a process known as diffusion. Oxygen is a byproduct of photosynthesis, while carbon dioxide is needed for the process to occur.
What is the purpose of stomatas in the leaf?
microscopic pores found under a leaf.
How does most carbon dioxide reach the photosynthesising cells of a green leaf?
Carbon dioxide enters the leaf through small pores called stomata located primarily on the underside of the leaf. Once inside the leaf, carbon dioxide diffuses into the cells containing chloroplasts, where photosynthesis occurs. This process allows the plant to convert carbon dioxide into sugars using light energy.
What does the oxygen molecule do when it is in the alveoli?
It diffuses into the blood capillaries surrounding the alveoli.
What part of the leaf do gasses pass in and out of?
Tiny little pores on the leaf's surface called Stomata
Which diffuses faster between chlorine and argon?
Chlorine diffuses faster than argon because it is a lighter and smaller molecule. This allows chlorine to move more quickly through a medium compared to argon, which is a heavier and larger molecule.
How does oxygen exit a leaf?

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.
