how do substances like CO2 and water move in and out of the cell?

Asked by Tanvi Abc(student), +1 more on 9/9/12

Answers

The sustance like co2 move in cell through the difussion

the substance like water move in cell through osmosis

This all happen when the concentration of substance like co2 and water is more outside the cell and concentration is less inside the cell so the water and co2 meve in through slectively permeabe membrane

the substances  CO2 and H2O moves inside the cells through difussion and  osmosis respectively  by passing through the cell membrane.

BY THE PROCESS OF DIFFUSION

Posted by Rishabh Jain(student), on 9/9/12

Substances like co2 accumulates in high quantity inside the cell than outside of the cell .so by the process of diffusion co2 moves from a region of high concentration to a region of low water concentreation.

Water moves in and out of the cell that is from the region of high water concentration to a region of low water concentration by the process of osmosis.the movement of water in and out of the cell also depend upon the solution whether high concentrated or not i.e. hypertonic, hypotonic or isotonic

 Carbon Dioxide :

Diffusion  is the movement of particles from a region of high concentration to a region of low concentration. 

Carbon dioxide is a waste product of respiration. It is at a high concentration in your cells  because the cells make it. 

The carbon dioxide molecules diffuse into the blood because there is a lower concentration in there than in the cells. This is because the blood is always moving, so the carbon dioxide is carried away and does not build up.

Water diffuses through the permeable membrane (permeable - allows some small substances/molecules to pass through but not other larger substances/molecules eg. oxygen (O2), water (H20) and carbon dioxide (CO2) can diffuse freely in and out of the cell. The diffusion of water through the plasma membrane is done via osmosis.
