Xylem and Phloem - Part 3 - Translocation - Transport in Plants

The video explains how water and minerals move up the plant through the xylem, driven by transpiration. It contrasts this with the phloem, where sugars and amino acids are actively transported in multiple directions. The phloem uses active transport to move sucrose from sources to sinks, with companion cells providing energy. The video concludes with a summary of these transport processes.
