In this episode, we look at transportation in cells. We will explainĀ how substances move into and out of cells, highlighting three key mechanisms.Ā
DiffusionĀ is described as the movement of particles from high to low concentration areas.Ā
OsmosisĀ is presented as a specific type of diffusion focusing on the movement of water across a semipermeable membrane.
Finally,Ā active transportĀ is characterized by the movement of particles against their concentration gradient, requiring energy.
The episode further clarifies the difference between diffusion and osmosis using the example of diluting blackcurrant squash in water.
