Is the cell membrane permeable in animal cells?
I assume you mean semi-permerable membrane that is permeable to the solution (water) but not the solute (salt). Osmosis can only occur if the membrane does NOT allow salt to pass through. Osmosis is the movement of water across a semi-permeable membrane from an area of low salt concentration to higher salt concentration.
How do diffusion osmosis facilitated diffusion and active transport diffusion differ?
Diffusion is the movement of molecules from an area of greater concentration to an area of lesser concentration. e.g. Exchange of gases in the lungs or body tissues. Osmosis is the diffusion of water through a semi-permeable membrane from an area of low solute to an area of high solute concentration. Faciliated diffusion is the passive transport of molecules down a concentration gradient. It is simply diffusion that involves a protein to make diffusion happen more easily across a cell membrane. Active transport is the moving of substances across the cell membrane using the cell's energy. Molecules are moved against a concentration gradient, i.e they move from an area of lesser concentration to an area of greater concentration. Tlhis is done by a carrier molecules which gets its energy from ATP.
Why does diffusion occurs?
To reach an equilibrium of concentrated solute particle. It's the process by which particles move from an area of high concentration to an area of low concentration. A simple reason why this occurs is that particles are always bouncing off each other, and an area with a high concentration of particles would be harder for a particle to bounce into than one with very few particles.
What type of osomosis does tap water have?
Osmosis is the diffusion of water molecules. You may be thinking about the filtration method termed "reverse osmosis". The movement of water depends on the difference in solute concentration ocross a selectively permeable (lets water in/out) membrane. So the osmosis of tap water depends on its solute concentration relative to the other side of a membrane. In general, water moves from areas of high concentration to low concentration. This is why cabbage wilts when placed in salty water (more solutes in salty water means lower concentration of fresh water relative to the plant cells, so water leaves the cabbage as the cells become flaccid).
What is the Relationship solute concentration solvent concentration in osmosis?
In any situation, the more concentrated a solution is in terms of solute, the less concentrated it is in terms of solvent. This is important in osmosis as you have to be careful which way round you express things, because it is water which moves from where there is a lot of it to where there is less. Thus you have to understand that if you have a high concentration of sugar, you have a lower concentration of water.
If there is more solute inside a membrane than outside solute particles will move across the membrane to the?
Concentration Gradient
What will happen to the solute when dissolved in solvent?
the particles of the solute would be spread to the solvent particles.
How does osmosis happen?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane
What is the difference between filtration and ultrafiltration?
Filtration is done by a filter paper, while ultrafiltration is done by a semipermeable membrane. Solute particles that are 1-200nm in diameter can pass through filter paper, but cannot penetrate the semipermeable membrane. Only particles with a diameter less than 1nm can pass through the semipermeable membrane.
What is the difference between facilitates diffusion and solute pumping?
Facilitated diffusion is an example of passive transport, while solute pumping is an example of active transport. This means that facilitated diffusion does not require the use of energy, while solute pumping does. Sometimes, certain particles are either too big or lipid insoulble to pass through the cell membrane. Therefore, they need a protein carrier which acts like a tunnel. This allows these particles to pass through the cell membrane. However, solute pumping is when amino acids, some sugars, and ions are transported b solute pumps. Also, ATP energizes during solute pumping. Facilitated diffusion is an example of passive transport, while solute pumping is an example of active transport.

What is the opposite of osmosis?
Because diffusion is the movement of solute particles while osmosis is the movement of solvent molecules through a semipermeable membrane.
What happens to the particles in a solid when it dissolved?
The particles in the solid (solute) break apart and form links with the particles in the liquid (solvent). There are strong forces of attraction between the molecules and particles inside the solute. These forces keep the particles together and make the solute a solid because they attract the solute particles tightly together. There are also strong forces of attraction between the molecules and particles inside the solvent. These forces keep the particles together and make the solvent a liquid because they attract the solvent particles slightly together. There is also an attractive force between the solute and solvent particles. To break these forces and from a bond between the solute and solvent particles energy is needed. This energy is gained from heat (the process of dissolving is speeded up through heat.) In conclusion, the particles in a solute break apart of their attractive forces and form bonds with the solvent particles through the attraction between the solute and solvent particles and through the energy gained by heat.
Osmotic pressure is created by the presence in a fluid of small difusible moleules that easily move through the capillary membrane?
Osmotic pressure is the force exerted by the movement of solvent molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This movement equalizes the concentration on both sides of the membrane. The osmotic pressure is directly proportional to the concentration of solute particles in the fluid.
Difference in osmosis and diffusion?
Diffusion is the spread of particles through random motion from regions of higher concentration to regions of lower concentration.... Osmosis is the net movement of solvent molecules through a partially permiable membrane into a region of higher solute concentration, in order to equalize the solute concentrations on the two sides....
What is the movement of water through a selectively permeable membrane?
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
What happens to particles of a solute when they dissolve?
When a solution forms, particles of the solute leave each other.
How do solute molecules pass through the membrane?
The solute molecule, when passing through the membrane passively using a carrier protein, is called the substrate. The solute, or substrate will bind to the carrier protein from the outside, the carrier protein changes conformation, and the substrate is exposed to the inside of the membrane.
