Just like a wall‚ the membrane is also somewhat permeable‚ except that the membrane takes a much more active role in determining what is allowed in to the cell and what is kept out. The plasma membrane is a very thin structure‚ which has some very important tasks. One of the main tasks that it performs

    move across the cell membrane is that the carbon dioxide molecules spread out rapidly out your red blood cells down their concentration gradient to your lungs. When water molecules move freely through your cell membrane is called osmosis as we learned last unit. The reason why molecules move across the cell membrane is because they are small molecules that have no charge like oxygen which the cell membrane need to survive. So basically the molecules that move across the cell membrane are necessary

    are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house

    Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation
