The larger the molecule, the slower the rate of the osmosis; and the smaller the molecule, the slower the rate of osmosis.

Diffusion is defined as a movement of molecules?
Is Diffusion the movement of molecules from a greater to a lesser concentration.
What is diffusion in cells?
diffusion- passive transport in cells where molecules move from an area where there are more molecules to an area of fewer molecules.
Which process describes the movement of molecules from areas of high concentration to areas of low concentration-?
diffusion. novanet.
Which homeostatic process is characterized by the diffusion of water molecules?
The homeostatic process is characterized by the diffusion of water molecules is called osmosis. The special case of diffusion that involves the movement of water molecules across a membrane.Ê
What are some molecules that move by diffusion and osmosis?
Gas molecules move by diffusion, and water molecules move by osmosis. Edit: Osmosis refers only to water molecules (H2O) while diffusion refers to all over molecules.
The rate of diffusion depends on?
Concentration of molecules, size of particles and temperature
What are factors on which rate of diffusion depends?
Diffusion depends on where the higher and lower concentrations of solutes are (molecules move from high to low concentration), what kind of membrane (if any) the molecules are moving through, and in many cases how large and charged the molecules are.
What conditions affect diffusion?
Factors that may affect Diffusion rates are: Temperature, Concentration, Different tissue types, Molecular size, Surface area to volume ratio.
Diffusion is defined as a movement of molecules?
Is Diffusion the movement of molecules from a greater to a lesser concentration.
How does kinetic energy affect diffusion rate?
The greater the collision rate, the greater the diffusion rate. As the molecules of the substance that is diffusing are more concentrated, the molecules collide more. As they diffuse and spread apart, there are less collisions and diffusion slows down.
How does the molecular rate affect rate of diffusion?
First, we must understand what diffusion is! Diffusion is the movement of particles from a high concentration to a lower concentration, in order to reach equilibrium. Cells in particular need this to maintain homeostasis, or an internal equilibrium (stability). Do you mean molecular size or composition, perhaps? Bigger particles are harder to move than smaller molecules. Additionally, physical constitution of a particle will affect the rate of diffusion. Think of a mouse squeezing under a door as compared to a rock, of the same size. A mouse will more easily be able to squeeze through the gap Edit The rate of diffusion is inversely proportional to square root of its inverse of its molecular weight
What is the movement of molecules from greater to lower?
Diffusion.
What factors most affect the rate of diffusion in a liquid or agas?
Two factors which determine the rate of diffusion of a liquid in another liquid include temperature and particle size. The higher the temperature, the faster diffusion takes place, and the smaller the particle, the faster diffusion takes place.
What is diffusion in cells?
diffusion- passive transport in cells where molecules move from an area where there are more molecules to an area of fewer molecules.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
In the diffusion of liquids through agar what characteristic of liquid determines the rate at which it will travel through the agar?
The size of the molecules.
Diffusion is the movement of molecules from?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
