Movement of carbon dioxide

  1. Carbon dioxide is a gaseous molecule that freely moves in and out of the cell by simple diffusion.
  2. The process in which molecules interact and move from an area of higher concentration to an area of lower concentration is known as diffusion.
  3. It does not indulge any need for energy as CO2 can move freely through the cell membrane.

Movement of water

  1. Water moves in and out of the cell by the process of osmosis which is a form of diffusion
  2. The process in which the molecules move from lower solute concentration to higher solute concentration through the cell membrane i.e. the water molecules move from the area of lower to higher concentration is known as osmosis.
  3. The movement of H2O needs a concentration gradient and no energy.

Therefore, the substances like carbon dioxide and water move in and out of the cell using diffusion and osmosis.

Summary:

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

The substances like carbon dioxide and water move in and out of the cell using diffusion and osmosis.
