The material used in this lab to simulate the permeability of a cell membrane is _________blank tubing.

The material used in this lab to simulate the permeability of a cell membrane is typically "dialysis tubing." Dialysis tubing mimics the semi-permeable nature of biological membranes, allowing certain molecules to pass through while restricting others. This characteristic makes it an effective tool for demonstrating how substances move across membranes in biological systems, which is fundamental to understanding cellular processes such as osmosis and diffusion. In experiments, the dialysis tubing can be filled with a specific solution and placed in another solution, allowing students to observe the movement of solutes and solvent across the tubing, simulating the behavior of cell membranes.
