LAB 9: TRANSPIRATION

In this lab, the movement of water within a plant was examined.

What are the general concepts you really need to know?

  • This lab closely followed the review of transpiration in this book. Review how water moves up a plant (from roots to leaves) via capillary action. Don’t forget the important properties of water related to transpiration—hydrogen bonding, polarity, and adhesion and cohesion.
  • Identify the different vascular tissues that are involved in transport in plants (xylem and phloem).
