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.
What determines the osmotic pressure of any given solution?
Osmotic pressure of saline (0.91% NaCl w/v) is arround 0.0085 ATM.The osmotic pressure is 7.58 ATM at 25 °C. P=MRT The molarity of 0.9% NaCl is 0.155M. But it has 2 ions per formula so 0.31 mol/L * 0.082 latm/Kmol * 298K= 7.58 ATM
What is the difference between hydraulic pressure and hydrostatic pressure?
Hydrostatic pressure is the pressure of a "standing liquid" and hydraulic pressure is the pressure in a fluid system that is being acted on by a compressor or pump. Let's look more closely. Let's say we're on a boat on the ocean and we slide over the side and into the water. We can feel the water pressure on us. As we move deeper into the water, that is, we dive deeper, the hydrostatic pressure increases. If we took ping pong balls with us as we dove deeper, they'd eventually be crushed by hydrostatic pressure. The pressure can be looked at as the weight of the water column (due to its height) on whatever is submerged. In a hydraulic system, a pump pressurizes the system to some level set by the controller and the safety (pressure release) systems. Some systems operate at pressures that are out of sight because they are so high. The hydraulic pressure is "artificial" in that a pump created it, and hydrostatic pressure is "natural" and is created by the weight of the column of the liquid creating it.
What is an example of tugor pressure?
Turgid pressure is the outward pressure that happens in a plant cell when the vacuoles and cytoplasm fill up with water. It pushes the plasma membrane against the cell wall of bacteria, plant, and fungi cells.
What are the causes of high suction pressure?
Suction is caused by an are of negative pressure.
How does water move during osmosis?
osmotic pressure should produce a net movement of water into a typical cell that is surrounded by water

What is the different between turgor pressure and diffusion?
The difference of turgor pressure and diffusion is that turgor pressure is an osmotic pressure exerted by the contents of a plant cell against its cell wall; while diffusion is a movement of molecules from an area higher concentration to an area lower concentration.
What is your conclusion to osmosis?
Osmosis can be defined by many example one is when slices of the potato are mixed with a high concentration of salt solution we can see the potatoes are shrink because the water from potato moves to the salt solution. Osmosis may occur when there is a partially-permeable membrane, such as a cell membrane. When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration (outside the cell) to one of high solute concentration (inside the cell), this is called osmosis. The cell membrane is selectively permeable, so only necessary materials are let into the cell and waste left out. Plant cell under different environments Osmotic pressure is the main cause of support in many plants. The osmotic entry of water raises the turgor pressure exerted against the cell wall, until it equals the osmotic pressure, creating a steady state.
All the factors that could cause water to evaporate.?
The most important factors are: temperature, pressure, water area exposed, stirring.
What happens to a animal cell in pure water an explain Why this does not happen in a plant cell?
Similar to placing an animal cell into water, the cell will swell and could burst, depending on the rigidity of the cell wall. This occurs because the osmotic pressure from dissolved solids is greater inside the cell than in the water. This osmotic pressure would then allow a passive diffusion of water into the area of greater solute density and thus expand the volume of the cell until equilibration or bursting.
Definition of osmosis?
The movement of water through a semipermeable membrane in order to equalize the osmotic concentration of a solute.Osmosis is the movement of water from an area of high water concentration (low solute) to an area of low water concentration (high solute).

How does turgo pressure help plants?
turgor pressure pushes the plasma membrane against the cell wall of plant, bacteria, and fungi cells as well as those protist cells which have cell walls. This pressure, turgidity, is caused by the osmotic flow of water from area of low solute concentration outside of the cell into the cell's vacuole, which has a higher solute concentration.
What is the tendency of water to move from an area of higher water concentration to an area of lower concentration?
osmosis. The water moves down an osmotic gradient from a dilute solution of ions to a move concentrated solution through a partially permiable membrane.
Why does malnutrition cause pot belly or cause like a pot belly in the stomach area?
They dont get enough protein in their diet so their capillary colloidal osmotic pressure goes down. This allows water to leak into the interstitium causing edema. Ascites (the name for pot belly in malnutrition) is when this fluid leaks into the peritoneal cavity (the space between the lining of the abdomen and abdominal organs) giving the appearance of a pot belly.
