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.

What is active transport, and why is it necessary for the movement of sucrose in the phloem?

Describe the difference in directionality of water transport in the xylem compared to sugar transport in the phloem.
