Introduction

How do the vascular tissues work?



A12.1 Xylem and phloem in a buttercup plant
The xylem vascular tissue and the phloem vascular tissue are in charge of the movement of materials, such as water and glucose, around the plant. This may seem very similar to our veins and arteries that carry blood around our bodies, but they work in a very different way. The xylem tissue uses the special properties of water to transport it and any dissolved minerals from the roots to the leaves.

In this lesson, we will study these special water properties and, by the end of the lesson, you will be able to explain how the xylem vascular tissue and the phloem vascular tissue work.

  Targets

By the end of this lesson, you will be able to

  • explain the transport system in plants
  • explain the xylem and phloem tissues and the processes of transpiration, including turgor pressure, osmosis, diffusion, active transport, and root pressure in root hairs
  • explain the cohesion and adhesion properties of water
