Question

(7) How do substances travel in the cell ?​

Answer 1

Answer:

Substances travel through the process of diffusion and osmosis in the cell and through the cell. The cell wall serves as a barrier for the substances to move through the cell. However, water, carbon dioxide and oxygen are some molecules that can cross the cell membrane by diffusion.
