How do CO2 and O2 move in and out of a plant leaf?
If you take a cross-section of a leaf and magnify it several times, you will see tiny pores on the underside. These holes are called stomata, and gaseous transfer takes place here, with carbon dioxide and oxygen entering and circulating inside the leaf. Waste gases from photosynthesis and respiration leave through the stomata as well. The oxygen diffuses out of the leaf because the concentration of oxygen is greater outside rather than inside the leaf (diffusion is the random movement of particles from an area of high concentration to an area of low concentration), down the concentration gradient. Likewise, the carbon dioxide diffuses into the cell because the concentration of carbon dioxide is greater outside the leaf than inside.
How does oxygen get out of the leaf cells and back into the air outside the plant?
Through a process called diffusion. This process is the random movement of molecules from an area of high concentration to an area of low concentration.
What happen when putting a peel of tradescantia into sodium chloride solution?
a leaf peeling of tradescantia is kept in 10% NaCl . after a few minutes we are likely to see exit of water from the cell.
What are small pores on the leaf surface called?
Small pores on the leaf surface are called stomata. They are responsible for regulating the exchange of gases, such as carbon dioxide and oxygen, during photosynthesis.
What do the stomata do for the leaf?
it gives the leaf food, carbon dioxide enters through tiny holes called stomata, Oxygen leaves plant through stomata. This is called respiration
When there is a low concentration of CO2 inside the lead do the stomata open or shut?
Hey, I figured it out when there is a low concentration of CO2 in the leaf the Stomata opens.
What does a larger number of leaf stomata indicate the growing climate of that plant?
A high concentration of of stomata indicates fast growth and that the plant lives in a wet climate.

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.
Where are the stomata located on the lower surface of a leaf?
The stomata are located on the lower surface of a leaf.
Is tradescantia monocot?
Yes, Tradescantia is a monocot because it belongs to the family Commelinaceae, which is a family of monocots. Monocots are characterized by having seeds with only one cotyledon or seed leaf, and Tradescantia exhibits this characteristic.
How do oxygen and carbon dioxide diffuse in and out of a leaf?
Oxygen and carbon dioxide diffuse in and out of a leaf through small openings called stomata. During photosynthesis, carbon dioxide enters the leaf through the stomata and oxygen exits. In the process of respiration, oxygen enters the leaf and carbon dioxide exits. This exchange of gases occurs through diffusion, where molecules move from areas of high concentration to areas of low concentration.
What are the small openings on a leaf that allow gasses to leave and enter the plant'?
It is controlled by a combination of the pressures/concentration gradients of the gases involved, and the guard cells of the stomata.
What is the small opening under a leaf called?
Stomata
How does carbon dioxide leAVE a leaf?
Carbon dioxide leaves a leaf through small openings called stomata on the surface of the leaf. The concentration of carbon dioxide inside the leaf is higher than in the atmosphere, causing it to diffuse out of the leaf through the stomata.
What happen when putting a peel of tradescantia into sodium chloride solution?
a leaf peeling of tradescantia is kept in 10% NaCl . after a few minutes we are likely to see exit of water from the cell.
