What is meant by osmosis?
Here's the definition of osmosis that you will see in most text books: In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
What is a passive transport in biology?
Passive transport is a naturally-occurring phenomenon and does not require the cell to exert any of its energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration.
What is required for osmosis to occur?
For osmosis to occur the membrane must be permeable to water but impermeable to the solute and the concentration of the solute must be different on the two sides of the membrane. The pressure that is just sufficient to prevent water from moving across the membrane is referred to as osmotic pressure.
What are 2 examples of osmosis?

What is a good example of osmosis?
An example of osmosis occurs when a sugar solution and water, top, are separated by a semipermeable membrane. The solution's large sugar molecules cannot pass through the membrane into the water. Small water molecules move through the membrane until equilibrium is established, bottom.
What is correct osmosis?
Osmosis is the process of the movement of solvent molecules through a semipermeable membrane. The energy which drives this process is called osmotic pressure. Osmosis is of great importance in biological processes in plants and animals both. Thus, the correct answer is option D.
Is osmosis only with water?
When people discuss osmosis in biology, it always refers to the movement of water. You can consider osmosis to be a special case of diffusion in which diffusion occurs across a semipermeable membrane and only the water or other solvent moves.
What is osmosis and its application?
Definition. Osmosis is referred to as the net transportation of solvent molecules between two solutions with different concentrations separated by a semipermeable membrane which is only permeable to the relatively smaller solvent molecules but impermeable to the larger solute molecules or ions.
What are the applications of reverse osmosis?
RO is now being used in various applications including selective separation, purification, and concentration processes. In food industry, RO is applied for concentration of fruits and vegetable juices, pre-concentration of milk and whey, and dealcoholization of alcoholic beverage.
What is the purpose of osmosis?
Osmosis refers to the movement of fluid across a membrane in response to differing concentrations of solutes on the two sides of the membrane. Osmosis has been used since antiquity to preserve foods by dehydration with salt or sugar. The removal of water from a tissue by salt was referred to as imbibition.
What are the examples of osmosis in daily life?
To better explain this phenomenon, we have listed a few very good examples of osmosis that we encounter in everyday life.
Does osmosis happen in humans?
Osmosis plays an important role in the human body, especially in the gastro-intestinal system and the kidneys. Osmosis helps you get nutrients out of food. It also gets waste products out of your blood.
