When the concentration of particles is the same on both sides?Explanation: When the concentration of particles is the same on both sides the cell has reached equilibrium . When the concentration of a substance is the same on both sides of a membrane The substance is?If the substance can cross the cell membrane, its particles will tend to move toward the area where it is less concentrated until equilibrium is reached. At that point, the concentration of the substance on both sides of the cell membrane will be the same. What happens during diffusion of molecules?Molecules can move into or out of cells by the process of diffusion . ... Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules. How do molecules move in diffusion?Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. ... The difference in the concentrations of the molecules in the two areas is called the concentration gradient. The kinetic energy of the molecules results in random motion, causing diffusion. 39 related questions found
A tea bag immersed in a cup of hot water will diffuse into the water and change its colour. A spray of perfume or room freshener will get diffused into the air by which we can sense the odour. Sugar gets dissolved evenly and sweetens the water without having to stir it.
Isotonic: The solutions being compared have equal concentration of solutes. Hypertonic: The solution with the higher concentration of solutes. Hypotonic: The solution with the lower concentration of solutes.
During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will: a. move across the membrane to the outside of the cell.
Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. ... The difference in the concentrations of the molecules in the two areas is called the concentration gradient.
Diffusion and active transport are two methods of transporting molecules across the cell membrane. Diffusion is a passive process, but active transport requires metabolic energy or an electrochemical gradient for the transportation of molecules across the membrane.
Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.
Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion. Some materials diffuse readily through the membrane, but others require specialized proteins, such as channels and transporters, to carry them into or out of the cell.
The concentration on both sides of the membrane will eventually reach DYNAMIC EQUILIBRIUM. The concentration of solutes will be the same on both sides of the membrane as water continues to move back and forth.
Diffusion of water molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal. ... the concentration of solute is the same on both sides of a membrane, and the cell volume will not change.
Diffusion occurs because molecules are always bumping into each other and moving from one to another concentration.
When the concentration is the same on both sides of the membrane, the movement of water molecules will be the same in both directions. At this point, the net exchange of water is zero and there is no further change in the liquid levels.
Concentration of a chemical in a solution refers to how many of the chemical's molecules are sitting in a small volume of the solution.
When the solute concentration outside the cell is higher than that in the cytosol, the solution outside is hypertonic to the cytosol, and water will diffuse outside of the cell.
Answer: (a) No, the two solutions do not have the same concentration.
Osmosis is a passive form of transport that results in equilibrium, but diffusion is an active form of transport. ... Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely.
A hypertonic solution is one that has a higher solute concentration outside the cell than inside. If a cell is placed in a hypertonic solution, the cell will shrink due to water osmotically moving out. ... Thus water molecules move from inside to outside the cell.
Some examples of diffusion that occurs in our daily life are given below.
The three types of diffusion are - simple diffusion, osmosis and facilitated diffusion.
The Diffusion Theory states that individuals go through a five-step process when adopting new ideas or innovations. These steps are awareness, interest, evaluation, trial and adoption (Surry, 1997). The first step in the process is awareness.

Robert J. Biology 6 months, 2 weeks ago During diffusion when the concentration of molecules on both sides of a membrane is the same the molecules will continue to move across the membrane… An isotonic solution is defined as two solutions of equal concentrations of solutes and water separated by a semipermeable membrane to allow water to move freely in and out of a cell. Learn the definition of an isotonic solution and explore real-world examples of it. Interpretation: Notice the rate of diffusion increases as the concentration gradient increases. If the concentration of molecules outside the cell is very high relative to the internal cell concentration the rate of diffusion will also be high. QUSTION: When the concentrations of solutions are the same on both sides of a membrane the two solutions are. Answer: Isotonic. If a cell is placed in an isotonic solution there will be no net flow of water into or out of the cell and the cell’s volume will remain stable. If the solute concentration outside the cell is the same as inside the cell and the solutes cannot cross the membrane then that solution is isotonic to the cell. When the solute concentration is higher in the external solution then the solution is known as a Hypertonic solution. It is a measure of the tonicity of the two solution systems.
Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid in this case) down its concentration gradient (into the cytoplasm). The passive forms of transport diffusion and osmosis move materials of small molecular weight across membranes. See also how long does it take to sail to europe When the concentration of solute and solvent are equal on both sides of the membrane?In an isotonic condition the relative concentrations of solute and solvent are equal on both sides of the membrane. There is no net water movement therefore there is no change in the size of the cell. During diffusion when the concentration of molecules on both sides of a membrane is the same the molecules will continue to move across the membrane… Which term describes when the concentration of a molecule is the same on both sides of the membrane?Since diffusion moves materials from an area of higher concentration to the lower it is described as moving solutes “down the concentration gradient.” The end result of diffusion is an equal concentration or equilibrium of molecules on both sides of the membrane. … What is the difference between osmolarity and tonicity?Osmolarity and tonicity are related but distinct concepts. … The terms are different because osmolarity takes into account the total concentration of penetrating solutes and non-penetrating solutes whereas tonicity takes into account the total concentration of non-freely penetrating solutes only. When solute concentration is equal on both sides of a semi permeable membrane?Membrane Transport 19.3) [4]. Osmotic pressure is the force required to prevent water movement across the semipermeable membrane. Net water movement continues until its potential reaches zero. When the concentration of solute is higher outside the cell?
A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell and the solutes cannot cross the membrane. If a cell is placed in a hypotonic solution there will be a net flow of water into the cell and the cell will gain volume. When the concentration of solute molecules outside the cell is equal to the concentration inside the cell the solution is?
Tonicity and cells
Hypertonic solution A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport particles will diffuse down a concentration gradient from areas of higher concentration to areas of lower concentration until they are evenly spaced. What kinds of molecules are involved in both active and passive processes of membrane passage?Channel proteins are used to transport materials in both processes. Carrier proteins are used to transport materials in both processes. Water moves through an aquaporin in both processes. ATP is required for both processes to occur. When molecules move down their concentration gradient they move from where they are?When molecules move down their concentration gradient they move from where they are more concentrated to where they are less concentrated. Diffusion across a biological membrane is called passive transport. When the concentration of solutes differ on the two sides?When the concentration of solutes differs on the two sides of a membrane permeable only to water what will occur? Possible Answers: Water will move across the membrane by active transport. Water will move across the membrane by facilitated diffusion. Diffusion is the movement of molecules from an area where the molecule is in high concentration to an area where the molecule is in lower concentration. … Facilitated diffusion is the movement of a molecule from an area of high concentration to an area of lower concentration with the help of a protein channel or carrier. Is osmosis and diffusion the same?Osmosis is a passive form of transport that results in equilibrium but diffusion is an active form of transport. … Osmosis only allows solvent molecules to move freely but diffusion allows both solvent and solute molecules to move freely. When both inside and outside of a cell have the same amount of water the cell has reached a stage of?when both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of equbilrium . When the concentration of a substance is the same throughout a space the substance is?
Biology (Ch. 4)
Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water. Salt is a solute when it is concentrated inside or outside the cell it will draw the water in its direction. During diffusion substances move from an area of high concentration to an area of low concentration until the concentration becomes equal throughout a space. Image showing the process of diffusion across the plasma membrane. Initially the concentration of molecules is higher on the outside. What do you call the phenomenon when you have a different concentration of materials on the inside and the outside of the cell?In passive transport substances move from an area of higher concentration to an area of lower concentration in a process called diffusion. A physical space in which there is a different concentration of a single substance is said to have a concentration gradient. What will eventually happen to the concentration on both sides of the membrane?
The concentration on both sides of the membrane will eventually reach DYNAMIC EQUILIBRIUM. The concentration of solutes will be the same on both sides of the membrane as water continues to move back and forth. … The cell in undergoing diffusion-water is moving from a higher to lower concentration.

A solution’s tonicity often directly correlates with the osmolarity of the solution. Osmolarity describes the total solute concentration of the solution. Does tonicity and osmolarity mean the same thing?They refer to the concept of concentrations of solutions and how they affect the osmotic pressure. However the way they express their effects is different from each other. … Therefore it can be said that tonicity is a measure of the external environment whereas osmolarity concerns the given solution itself. What is the relationship between tonicity and osmotic pressure?
Osmotic pressure and tonicity often are confusing to people. Both are scientific terms pertaining to pressure. Osmotic pressure is the pressure of a solution against a semipermeable membrane to prevent water from flowing inward across the membrane. Tonicity is the measure of this pressure. What is the relationship between tonicity and osmosis?“Tonicity is the ability of a solution to affect the fluid volume and pressure in a cell. If a solute cannot pass through a plasma membrane but remains more concentrated on one side of the membrane than on the other it causes osmosis.” The osmotic pressure driving water across an impermeable barrier increases with the difference in solute concentrations on either side of the barrier. … Osmotic pressure depends only on the number of solute particles not on their composition. Which side of the beaker is hypertonic?A beaker is divided by a selectively permeable membrane. To the left side of the partition a hypotonic glucose solution is added and to the right side a hypertonic glucose solution is added. When the concentration is the same on both sides outside and inside the solution is?If a cell is placed in an isotonic solution there will be no net flow of water into or out of the cell and the cell’s volume will remain stable. If the solute concentration outside the cell is the same as inside the cell and the solutes cannot cross the membrane then that solution is isotonic to the cell.
