360Science™: Rate of Transpiration

firewatch

In this lab, the stomata, which regulate transpiration, will be observed, counted, and quantified. Pooling the class data, students will determine the average number of stomata per square millimeter of the plant species being tested.

Concepts

  • Transpiration
  • Adhesion
  • Cohesion
  • Osmotic potential
  • Turgor/pressure potential
