What gases move into or out of our bodies by diffusion?
Oxygen moves into our bodies by diffusion, while carbon dioxide moves out of our bodies by the same process. Oxygen is taken in by our cells for cellular respiration, while carbon dioxide is the waste product produced by this process and is expelled from the body.
What sausage shaped cells control the size of opening that allow carbon dioxide and oxygen to move into and out of a leaf?
Guard cells control the size of openings called stomata on the surface of leaves. When the guard cells take up water, they swell and cause the stomata to open, allowing carbon dioxide to enter for photosynthesis. When they lose water, the guard cells shrink and the stomata close to prevent excessive water loss.
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.
The cells lining the air sacs in the lungs make up a?
The cells lining the air sacs in the lungs make up the alveolar epithelium. These cells are responsible for gas exchange, allowing oxygen to move from the air into the bloodstream and carbon dioxide to move out of the bloodstream into the air sacs to be exhaled.
Why does carbon dioxide moves into red blood cells by diffusion rather than by active transport?
Do you mean why does carbon dioxide diffuse out of the cells into the bloodstream? Diffusion is the movement of particles from a region of high concentration to a region of low concentration. Carbon dioxide is present in your body cells at a high concentration because the cells are making it. The process which makes carbon dioxide in cells is respiration. This is the release of energy from food. Carbon dioxide is a waste product of respiration. The carbon dioxide molecules diffuse into the blood because there is a lower concentration in the than in the cells. This is because the blood is always moving, so the carbon dioxide is carried away and does not build up. The difference in concentration between the cells and the blood keeps carbon dioxide diffusing in the correct direction.

How do carbon dioxide and oxygen move in and out of cells?
Carbon dioxide diffuses out of cells into the bloodstream and is transported to the lungs to be exhaled. Oxygen is taken up by red blood cells in the lungs and transported to cells where it diffuses into the cells to be used for energy production.
What gas moves into or out of cell diffusion?
Oxygen and carbon dioxide move into and out of cells through diffusion. Oxygen diffuses into cells to be used in cellular respiration, while carbon dioxide diffuses out of cells as a waste product of this process.
What sausage-shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of a leaf?
Guard cells control the size of openings (stomata) that allow carbon dioxide and oxygen to move into and out of a leaf. Guard cells change shape to open or close the stomata in response to environmental conditions like light intensity, humidity, and carbon dioxide levels.

What are the hollow spheres of cells within the lungs where oxygen and carbon dioxide are exchanged?
The alveoli are the hollow spheres of cells within the lungs where oxygen and carbon dioxide are exchanged. They are thin-walled, and closely associated with the thin-walled capillaries that surround them. Oxygen and carbon dioxide diffuse across these thin walls to move from the blood to the lungs.
What sausage shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of of a leaf?
The guard cells of a stoma perform this function.
