Osmosis is the transfer of solvent from a region of lower concentration to a region of higher concentration. Explore more about the definition of osmosis and osmotic pressure.
Hence the process of osmosis is so important as cells can burst if they take on too much water, or collapse if they lose too much. Osmolarity vs Molarity Molarity of a solution is defined as the concentration of a solute in that solution. It tells you how much of a solute is present....
it is the diffusion of solutes across a selectively permeable membrane. a selectively permeable membrane is one that allows only specific ions and molecules to pass through, while it obstructs the movement of others. osmosis: it is the movement of solvent molecules from the region of lower ...
Regarding Osmosis, why is a solvent poured into a cell with higher concentration needed in order to equalize it? Explain. Which process moves water molecules across the membrane of a cell? What is molecular movement in biology? Explain and give examples of cellular transport such as osmosis, ac...
In biology, this is a difference between the two processes. One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane. This can be confusing because ...

Osmosis:Osmosis might be described as a "sucking pressure" that causes the movement of water when the movement of particles dissolved in the water is impossible. This occurs when a membrane allows water, but not the dissolved particles ("solutes") in question, to pass through it. The driving...
Reverse osmosis is not a new purification technique. The first examples of osmosis through semipermeable membranes was described by Jean-Antoine Nollet in 1748. While the process was known in laboratories, it wasn't used for desalination of seawater until 1950 at the University of California in Lo...
What is osmosis as used in most processes of biology? When a cell is placed in a hypotonic solution what will happen? What type of solution is 100 percent distilled water in comparison to a cell? a. hypertonic b. hypotonic c. isotonic Will a plasmolysed cell be still alive and fully...
“In science, we define ‘creativity’ as an idea that is novel, good, and useful. It’s a little broader than the Oxford Dictionary’s definition, where it’s just the ability to create, because that doesn’t really say much. You can create something and it’s not very useful or it...
