Question

how do substances like CO2 , O2 and 2ater move in or out of the cell. Explain
​

Answer 1

Explanation:

The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. ... When the concentration outside the cell becomes low and it is high inside the cell, they moves out.

Answer 2

• Water, carbon dioxide, and oxygen moves across the cell membrane by the process of diffusion (or osmosis for water molecules).

• CO2 which is a cellular waste gets accumulated in the cell. In the cells external environment, the concentration of CO2 is lower as compared to that inside the cell.

• As soon as there is a difference in concentration of CO2 inside and outside the cell, carbon dioxide moves from a region of high concentration to a region of low concentration.

• Similarly O2 also enters the cell by the process of diffusion when the concentration of O2 decreases inside the cell
