Osmosis is simply the diffusion of water across a membrane - again from high to low concentration. In order to move against the concentration gradient from low to high concentrationparticles must
How do osmosis and dialysis releate to diffusion? Osmosis is the the diffusion of water or any soluble liquid across a semipermeable membrane such as the outer membrane of a cell. When water moves out of the cell faster then… the intake of water, the cell will shrink.
This is a hypertonic solution.
When the intake is greater than the output, the cell will grow. This is a hypotonic solution.
When a balance is achieved, water moving equally in and out of the cell, an isotonic solution is created. For example, a biology class put an egg in a vinegar solution. This causes the egg to grow because the vinegar was at a higher concentration then the inside of the egg and biology states that it will flow from a high concentration to low concentration.
When that same egg is placed in water, the vinegar flows out of the egg because the water was a lower solution of vinegar than the egg. So all of this comes down to the fact that in both osmosis and dialysis, something is being diffused through the cell's semipermeable membrane.
If you need a clearer explanation, ask you school's biology teacher s.The rate of absorption of water is lower, if the temperature is lowered this is because the mobility of water is decreases and the viscosity of liquid water increases.
Thus low temperature resists the free movement of water which in turn affects the rate of absorption. More the surface area to volume ratio, more is the diffusion. Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time.
Amoeba and some bacterias are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area. The surface area of the exchange membrane also affects the rate of diffusion.
The larger the surface area of the exchange membrane the faster particles diffuse. increasing the temperature will give particles more kinetic energy, making them move faster, thus increasing the rate of diffusion. Osmosis: Osmosis is the diffusion of water molecules.
AP Bio Osmosis and Diffusion lab Essay. Diffusion and Osmosis Lab Introduction: 1) The relationship between the rate of diffusion, volume and surface area is that the surface area of a subject somewhat correlates with the volume of the object. Osmosis is much slower than the rate of diffusion.
Osmosis is a inactive conveyance of H2O whereas diffusion is a inactive conveyance of solutes. We will write a custom essay sample on How Does The Concentration Affect Osmosis Biology Essay specifically for you.
Jun 11, · Cells need to excrete wastes and release heat at the same rate as it produces wastes and heat. If the cell becomes too large, there will not be enough surface area to excrete all the wastes and release all the heat produced by the cell (the volume is too much).Status: Resolved.
