A Level Biology Revision "Movement of Water Through the Roots of a Plant"

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/...

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.
