How do substances like CO2 and water moves in and out of the cell? Discuss
The exchange of gases CO2 and O2 between cells takes place by diffusion process. Diffusion is the migration of a chemical from a high-concentration region to a low-concentration zone. CO2 is produced inside the cell as a result of respiration and accumulates in the cell, resulting in a high concentration of CO2 in the cell compared to the outside environment. However, because O2 is used inside the cell during respiration, its concentration declines inside the cell while remaining relatively high in the environment. As a result, CO2 diffuses out of the cell and O2 diffuses in.
