AS Biology, Plant transport Topic - Translocation. Explanation of sources and sinks and how assimilates move by mass flow through the phloem. Includes details of active loading in the companion cell, using proton pumps and cotransporters.
it is a shame this isn't what comes up first when looking for A Level B biology stuff because this channel is so underrated compared to other bio a level channels, especially for visual learners, the fact you draw everything out instead of using static images really really helps, thank you so much.
Your explanation is very detailed and clear which makes it easy to understand. Just found ur channel and im so glad since i will sat for the CIE As level bio next yr hopefully. Appreciate the good work!
