This experiment aimed to understand cellular activities aided by examining cell membranes and transport using fluorescence microscopy. It enables us to see the dynamics and structure of cell membranes and the procedures involved in moving molecules across them up close. Knowledge of this is crucial to understanding the basic mechanics behind cellular activity.
2 observations I made two observations in the simulation: Aquaporins are a means of transporting water molecules as long as those molecules are transported by aquaporin against an electrochemical gradient. I also observed that some cell membranes selectively allow certain molecules and ions to pass through while it blocks others from doing so.

The term "tonicity" describes the difference in solute concentration between the inside and exterior of a cell, which affects the condition of the cell and water movement.
Patients are given a hypotonic intravenous fluid when their cells need to absorb water. Sometimes, a hypotonic IV solution is used when a patient is dehydrated. The hypotonic solution aids by rehydrating cells by encouraging water to migrate from the extracellular space into the cells.
The 2 key concepts that interested me were selective permeability and active transport.
