Question

How do substances like Co2 and water move in and out of the cell??


(ncert, chapter the fundamental unit of life class 9)​

Answer 1

Through the process of diffusion the substances like CO₂ and O₂ move in and out of cell from the region of high concentration to low concentration.

When the concentration of CO₂ and water is higher in external environment than that inside the cell, CO₂ and water moves inside the cell. When the concentration outside the cell becomes low and it is high inside the cell, they moves out.
