Movement of Water Through the Roots of a Plant

In this video, we look at how water moves through the roots of a plant. First we look at how root hair cells are adapted for the maximum rate of absorption of water and mineral ions. We then explore how water moves through the cortex via the symplast and apoplast pathways. Finally, we look at how water moves through the endodermis, including the roles of the Casparian Strip and Root Pressure.
