Question

name the physical process by which gaseous substance can move across the plasma membrane how does it occur?​

Answer 1

:Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.

Answer 2

Answer:

Diffusion.

Explanation:

Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration. This movement occurs because the molecules are constantly colliding with one another. The net movement of the molecules is away from the region of high concentration to the region of low concentration.
