Diffusion can occur in any medium, whether it is liquid, solid, or gas. The middle of the bilayer is an area without water.
Factors Affecting the Rate of Osmosis Temperature - The higher the temperature, the faster the movement of water molecules across the semi permeable membrane.
To answer the question, you need to know the definitions of osmosis and diffusion and really understand what they mean. What would happen if a cell dissolved in water, like sugar does?
Simple diffusion and osmosis do not involve transport proteins. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Another example of a harmful osmotic effect is the use of table salt to kill leeches and slugs.
It is the movement of water from high water concentration to low water concentration. The key to remember about osmosis is that water flows from the solution with the lower solute concentration into the solution with higher solute concentration.
This can be confusing to understand because while the solvent particles are moving from higher to lower solvent concentration across the membrane, they are moving from lower to higher solute concentration from a more dilute solution to a region of more concentrated solution.
Tonicity When thinking about osmosis, we are always comparing solute concentrations between two solutions, and some standard terminology is commonly used to describe these differences: Isotonic: The solutions being compared have equal concentration of solutes.
In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration. The concentration of the diffusion substance equalizes to fill the available space.
