Translocation is the movement of dissolved substances (also called solutes or assimilates) through the phloem vessels. If you haven't already, make sure to read about the structure of the phloem vessels here first so you've got a good grounding to take this topic further. Source to Sink Solutes move from a source to a sink.... Continue Reading →
Water Transport in Plants – Exchange and Transport Ep 15
In the last post we looked at the structure of the xylem vessels, so now we're going to take a look at their function. Water transport in plants happens up the xylem vessels in a transpiration stream from roots to leaves due to the properties of water and transpiration at the leaves. Let's break the...

Xylem and Phloem Structure – Exchange and Transport Ep 14
Today we're starting on transport in plants. Plants don't have hearts or blood, but they still need to transport substances around because they are too big to rely on diffusion alone. The tissues involved in transport are the xylem vessels and the phloem vessels. In this article we will focus on the xylem and phloem... Continue Reading →
