**Membrane Simulation: Diffusion and Osmosis**In the scenario shown above, observe the simulation where the green spheres represent glucose molecules and the blue dots represent water molecules. The simulation models the process of diffusion across two membranes.### Explanation of the Simulation1. **Visual Elements:** - **Green Spheres:** These are glucose molecules. They are larger and are shown moving slowly, illustrating how larger molecules move through membranes. - **Blue Dots:** These are water molecules, smaller in size, moving more freely through the membrane, representing their role in osmosis.2. **Membrane Structure:** - The diagram includes two barriers, symbolizing selectively permeable membranes with variable pore sizes. These are represented by gaps in the barriers, allowing different rates of molecule passage.### Key Concepts:- **Diffusion:** The movement of molecules from an area of higher concentration to an area of lower concentration. In this simulation, both glucose (to a lesser extent) and water molecules exhibit this movement.- **Osmosis:** A specific kind of diffusion concerning the movement of water molecules across a semipermeable membrane. ### Observational Focus:- Notice how water molecules (blue) move more freely compared to glucose (green). This exemplifies the differences in permeability for different substances across a membrane. **Question for Consideration:**In the scenario above, the green spheres are glucose molecules, and the blue dots are water molecules. What form of transport is being observed?**Educational Task:**Watch the video clip linked in the simulation to further explore these concepts and answer the posed question regarding molecule transport across membranes.
