Understanding Selective Permeability

The video tutorial explains how materials move in and out of cells through the cell membrane, using a mesh bag as a demonstration tool. The bag's holes represent the selective permeability of the cell membrane, allowing some materials to pass while blocking others. This concept is crucial for understanding cellular processes.
