Question

Explain how diffusion facilitates the
movement of Oxygen and carbon-
dioxide in and out the cell.
respectively?

Answer 1

Answer:

For Animal...... As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. ... Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell.

For Plant .....

Carbon dioxide diffuses from the air through tiny pores in plant leaves called stomata. Oxygen produced by photosynthesis diffuses from the plant through the stomata into the atmosphere. In facilitated diffusion, larger molecules such as glucose, can not freely diffuse across cell membranes.....

Answer 2

Due to the diffusion there is movement of Oxygen and Carbon dioxide in and out of the cell.

Explanation:

• When the amount of carbon dioxide in a Cell increases then the carbon dioxide due to the process of diffusion  moves from the cell to the veins. This when carry the deoxygenated blood to the lungs.

• Again in the lungs due to diffusion carbon dioxide moves from the vein to the the Airways where carbon dioxide is removed from the body. In a similar process oxygen enters the body and gets circulated
