General category: Biology.

Sub-category: Cellular membranes

Topic: Diffusion

Introduction:

Diffusion is the random movement of molecules in a given medium toward a state of equilibrium. Then, diffusion is the net movement from regions of greater concentration to regions of lesser concentration.

Step-by-step explanation:

First of all, remember that if a cell membrane divides a solution into separate compartments, the movement of the different solutes can be affected by the properties of the membrane. The passage of substances depends on whether the membrane is permeable or semi-permeable to different solutes.

Now, the concept of osmosis is based on the idea of diffusion. Osmosis is the diffusion of water across membranes. This means that water will diffuse from a region of its higher concentration (lower concentration of solutes) to a region of its lower concentration (higher concentration of solutes).

Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function. Remember that osmotic equilibrium is the ratio of intracellular fluid to the extracellular fluid. For example, osmotic balance is of vital importance in the functioning of the nephron.

We can conclude that the correct answer is:

Answer:

Osmosis:

Osmosis is the diffusion of water across membranes where the water will diffuse from a region of its higher concentration to a region of its lower concentration.

Biological importance of osmosis:

Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function.

Step-by-step explanation:

osmosis

refers to 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 cells partially permeable membrane

Importance

- it stabilizes the internal environment of the organism by balancing the level of water and intracellular fluids
