Osmosis is a form of passive transport. Which defines osmosis?

Osmosis? Oh, you mean when water decides to take the path of least resistance, like a lazy river ride? Well, osmosis is indeed a form of passive transport. It's like the water just letting itself be dragged along to where the concentration of solutes is higher. You can think of it as the water saying, "Alright, fine, I'll go where the party's at, but only because it's easy!"

Osmosis is indeed a form of passive transport. To define osmosis, we need to understand the concept of passive transport first. Passive transport refers to the movement of molecules or substances across the cell membrane without the need for energy expenditure by the cell. In other words, it occurs spontaneously along the concentration gradient.

Now, specifically in the case of osmosis, we are referring to the movement of water molecules across a selectively permeable membrane (such as a cell membrane) from an area of lower solute concentration to an area of higher solute concentration. This movement is driven by the concentration gradient: where there is a higher concentration of solute, water molecules tend to move in that direction to equalize the concentration on both sides of the membrane.

In simpler terms, osmosis is the process by which water flows through a cell membrane from an area with low solute concentration (more water) to an area with high solute concentration (less water), until equilibrium is achieved.

To determine whether or not osmosis is occurring in a particular circumstance, you would need to observe if water is moving across a selectively permeable membrane in response to a concentration difference. This can be done through various experimental setups, such as using a semi-permeable membrane, measuring changes in water volume, or monitoring solute concentrations before and after the process.

Osmosis is a process in which the solvent molecules (usually water) move across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the solute concentrations on both sides of the membrane. It is a form of passive transport because it does not require the input of energy from the cell.
