**Educational Transcript: Membrane Diffusion and Osmosis****Section Overview:**In this section, we explore the concept of diffusion and osmosis across two membranes using a simulation.**Visual Aid Description:**- A screenshot from a membrane simulator video demonstrating diffusion and osmosis.- The screen shows a division with two different areas separated by membranes.- Green spheres represent glucose molecules, and blue dots represent water molecules.**Instructions:**Watch the video clip to understand how molecules move across the membranes and answer the following question:"In the scenario shown above, the green spheres are glucose molecules, and the blue dots are water molecules. In terms of concentration, will this solution reach equilibrium?"**Video Controls:**- Play/Pause button for the video is available.- A slider controls the "Pore Size" in the simulation, influencing the passage of molecules.- The video includes tracing options to monitor individual molecules.Understanding these concepts is crucial for comprehending how substances move in biological systems.

Diffusion is very important process of nature where substances present in excess amount will move…

The plasma membrane has a hydrophobic interior due to the two present in each phospholipid found in the phospholipid bilayer of the cell membrane. The plasma membrane allows some molecules to cross but not all. Therefore, the plasma membrane is said to be Molecules that are nonpolar and hydrophobic will cross the membrane with ease by Does this process require energy? When molecules move across the plasma membrane by passive transport, they will move down or with the_ from an area of concentration to an area of. concentration. Polar, hydrophilic molecules and charged ions will move across the plasma membrane by the process of_ This does not require energy, but it does require a A special case of diffusion is known as which is the movement of water across the plasma membrane.

Two containers with solutions of sucrose in water are connected by a semipermeable membrane that is only permeable to water. Each container has a piston above it. Using this information answer the following. If the concentration of sucrose in solution A is 150mM and in solution B it's 2mM, which of the following would occur? al Piston D will feel an upward pressure. No diffusion will occur. Sucrose will diffuse from solution A to soluion B. Piston C will feel an upward pressure.
