Factors that influence rate of diffusion
- The rate of diffusion depends on the concentration difference across the two sides of the membrane.
- The rate depends on the permeability of the plasma membrane to the diffusing substance.
- The rate of diffusion depends on the temperature of the solution.
- The rate of diffusion through a membrane is also directly proportional to the surface area of the membrane, which can be increased by such adaptations as microvilli.
the thickness of the cell membrane
the mass of the solute particles
the difference in the initial concentration gradient
*these are also factors that influence the rate of diffusion between extracellular and intracellular environments

What will happen if a partially permiable membrane is replaced with a non permiable membrane?
If a partially permeable membrane is replaced with a non-permeable membrane, no substances will be able to pass through the membrane. This will prevent the movement of molecules across the membrane and alter the osmotic balance between the two sides of the membrane. This could lead to changes in cell volume and affect cellular processes that rely on osmotic balance.
What does the plasma membrane do?
The plasma membrane is like the skin of the cell and lets only certain things in and out. It uses active and passive transport to let things in and out meaning that it uses energy only sometimes to let things in and out (this being active) and lets things move as they please at other time (this being passive)
Does increasing membrane permeability affect the time it takes for the osmometer to reach equilibrium?
Yes, increasing membrane permeability can affect the time it takes for the osmometer to reach equilibrium. Higher permeability allows for faster movement of solvent and solutes across the membrane, which can result in a quicker establishment of equilibrium between the two solutions.
What are the three things that affect diffusion?
Three main factors that affect diffusion are temperature (higher temperature increases rate of diffusion), concentration gradient (greater difference in concentration leads to faster diffusion), and surface area (larger surface area allows for more diffusion to occur).
What environmental factors affect diffusion?
Diffusion is affected by various environmental factors, like temperature.

What factors affect the diffusion of water?
One of the factors that affect the diffusion of water through a membrane by osmosis is the permeability of the membrane. The amount of water on each side of the membrane may also have an effect on water's diffusion. Water will diffuse to the side with little water to even out the concentration.
How do diffusion and osmosis affect cells?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, which helps cells take in nutrients and get rid of waste. Osmosis is the diffusion of water across a selectively permeable membrane, allowing cells to maintain their internal balance of water and solutes. Together, diffusion and osmosis are essential processes for cells to function properly and maintain homeostasis.
What factor affect osmosis?
Factors that affect osmosis include concentration gradient, pressure, temperature, and permeability of the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
What is osmosis and facilitated diffusion?
Diffusion is the net movement of particles(atoms,ions or molecules) from a region where are of higher concentration to a region where they are of lower concentration, down a concentration gradient.Factors that affect the rate of diffusion1.Temperature2.the concentration gradient3.Physical movement4 surface area to volume ratioThe passage of water from the less concentrated solution to the more concentrated solution across a partially permeable membrane is a process called osmosis
How does the cell membrane affect the contents of the cell?
It selectively lets things transport into and out of the Cell.
What will happen if a partially permiable membrane is replaced with a non permiable membrane?
If a partially permeable membrane is replaced with a non-permeable membrane, no substances will be able to pass through the membrane. This will prevent the movement of molecules across the membrane and alter the osmotic balance between the two sides of the membrane. This could lead to changes in cell volume and affect cellular processes that rely on osmotic balance.
How will an increase in cholesterol content in the plasma membrane affect the overall properties and functions of the membrane?
An increase in cholesterol content in the plasma membrane can make the membrane more rigid and less permeable. This can affect the membrane's ability to transport molecules, communicate with other cells, and maintain its structure.
How does surface area affect diffusion rate?
Diffusion is the movement of particles across a selectively permeable membrane, from a high concentration to a low concentration. So the larger the surface area, the quicker the rate of diffusion because there is more space to diffuse in.
How does osmotic potential affect diffusion?
Osmotic potential influences the movement of water molecules across a semi-permeable membrane. When there is a difference in osmotic potential between two solutions separated by a membrane, water will move from the area of lower solute concentration (higher water potential) to the area of higher solute concentration (lower water potential) to balance the concentrations. This affects the rate and direction of diffusion of solutes in and out of cells.
How the variation of pH affect the permeability of beet root plasma membrane?
Decreasing the pH from alkaline to acidic denatures the proteins within the membrane, making them less functional and efficient. This makes the cell membrane more permeable and allows the red dye, betalain to escape into the external solution via diffusion. The dye goes down a concentration gradient from a higher to a lower concentration.
How does diffusion affect the movement of water?
Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration. In the case of water, diffusion can affect its movement by causing it to spread out evenly in a solution or across a membrane. This can help to balance the concentration of water molecules on both sides of a barrier, such as a cell membrane, allowing for the movement of water to occur more easily.
