Plasma membranes are selectively permeable. The purpose of this experiment is to reveal how a form of diffusion in a semipermeable membrane works by creating a real life simulation of a semipermeable plasma membrane. This is done by building an imitation of a caterpillar’s digestive tract using dialysis tubing and glassware. The first material in this experiment is a small beaker representing the head and crop of the caterpillar. This beaker is filled with both starch and the enzyme α-amylase. This

An experimental lab conducted in class was tested‚ essentially to observe the effects of diffusion/osmosis. More specifically‚ according to‚ “merriam-webster.com/dictionary/diffusion‚” the process of diffusion causes particles to spread
