Osmosis

Transpiration is not a type of osmosis. Transpiration is the process by which water is absorbed by plant roots and released as vapour through the plant's leaves. Osmosis, on the other hand, is the movement of water molecules across a semi-permeable membrane from an area of higher water concentration to an area of lower water concentration.

I've seen it in Singapore

no

It is better then any other because it shows the concentration of water from an area of high concentration to an area of low concentration. It also shows water passing through a permeable membrane requireing NO energy at all.

Diffusion is when materials move from areas of high concentration (high amount) to areas of low concentration (low population).Osmosis is the same as diffusion, but it's only when WATER moves from areas of high concentration to areas of low concentration. STAY IN SCHOOL JUNIORS!!(and pee-wees too. . .)

Salt causes osmosis because it is a solute that creates a concentration gradient across a semi-permeable membrane. Water molecules move from an area of low solute concentration to an area of high solute concentration to try to equalize the concentration on both sides of the membrane, resulting in osmotic pressure.

It's easier to understand the similarities between osmosis and diffusion if we look at their differences.

Basically, diffusion is the random motion of particles along the concentration gradient (simply particles moving from high to low concentration)

Whereas osmosis is specifically the motion of water molecules across a selectively permeable membrane (think cell membrane) from an area of high water concentration (or potential) to an area of low water concentration (or potential)

So what's the same?

they both:

follow the gradient (high to low concentration) meaning they

do not require energy to occur

will continue until concentrations are equal on both sides

there are more similarities, but it might be easier just remembering that osmosis is just selective diffusion (esp for solvent molecules, most often water)

Osmosis is the diffraction of water through a permeable membrane using no energy, whereas active transport is the moving of particles across a membrane against a concentration gradient.

Basically, Osmosis moves water with no energy. Active transport moves particles, in general, with the use of chemical energy like ATP.

diffusion where solvent molecules move through a semi-permeable membrane from an area of higher concentration to an area of lower concentration. It is a passive process that helps to balance solute concentrations on either side of the membrane.

Someone has too much time on their hands.

when higher concentration and lower concentration are getting contact then a potential differences occurs and which generates electricity ,and that process is called osmosis ..

and when sea water gets contact with river water it generate electricity that process is called river osmosis...

how do you calculate the rate of osmosis

In osmosis, water molecules move from an area of high water concentration to an area of low water concentration across a selectively permeable membrane, such as a cell membrane. This process helps to balance the concentration of solutes on both sides of the membrane.

Water is NOT osmosis. Although, osmosis is a special term used for the diffusion of water (moves from area of high concentration to low concentration). Used to identify that it is water being diffused, commonly in biology.

Osmosis is the movement of solvent molecules (typically water) from an area of lower solute concentration to an area of higher solute concentration through a semipermeable membrane. It is a passive process and does not require energy input. Osmosis helps maintain water balance in cells and plays a key role in processes like nutrient uptake and waste removal.

Osmosis is a passive form of diffusion as it travels downa concentration gradiant, as opposed to active transport; a type of diffusion that can go against a conc. grad.

Diffusion is the movement of particles from an area of high concentration to that of a low concentration. Osmosis is the transfer of a solvent (usually water) through a semi-permeable membrane from an area of high concentration into an area of low concentration.

1.] Isotonic - concentrationg is the same on the outside and inside [dynamic equilibrium]

2.] Hypotonic - concentration of substances lower outside the cell, water flows in, turgor pressure increases, and cell bursts

3.] Hypertonic - concentration of substances higher outside the cell, water flows out and cell shrinks

For hypotonic solution, it means that the solution has lower concentration of solutes (salt, sugar etc) than inside the cell. If it is an animal cell, water will move from the hypotonic solution to inside the cell and the cell will swell and burst open. This is called cytolysis. For the plant cell, water will enter the cell and the cell wall enables the plant cell to swell and become turgid without bursting.

For hypertonic solution, it's actually the opposite of hypotonic solution.It actually means that the solution has higher concentration of solutes than inside the cell. For the animal cell, water leaves the cell through osmosis and it will shrink and tiny spikes appear on the cell membrane. This is called crenation. For the plant cell, its cytoplasm shrinks away from the cell wall. This is called plasmolysis.

Last but not least, the isotonic solution! This means that the concentration of solutes in the solution is equal to the conc of solutes inside the cell. The result: water moves equally in both direction and cell remains the same size. That's called dynamic equilibrium!

Isotonic, hypotonic, and hypertonic.

reverse osmosismay be define as a separation operation involve transfer by concentration gradient of a solvent through membrane in to a mixture solute and solvent , the transfer of solvent in the opposite direction is effected by imposing the pressure . is known as reverse osmosis

Osmosis is the movement of water across a partially permeable membrane down the concentration gradiant from an area of high concentration to an area of low concentration until an equilibrium is achieved.

Osmosis certainly does happen regularly in real life. Osmosis is the transportation of water from one side of a membrane to the other side of a membrane.

Osmosis is vital for maintaining the balance of water and solutes within living cells. It allows a cell to regulate its internal environment and ensure proper functioning. Osmosis is also key for nutrient uptake in plants and is essential for processes like kidney function and blood pressure regulation in animals.
