question 1 of 3

A student coats the lower and upper surfaces of half of the leaves on a small plant with petroleum jelly. She places the plant in a potometer, and compares the rate of transpiration in this set-up (set-up Q) with that of another plant of the same species and similar surface area (set-up C.) Which statement most likely states and explains her results?

About This Quiz & Worksheet

Transpiration is an important function in the biology of a plant, and this quiz/worksheet combo will help you test your understanding of the vocabulary surrounding the word. Some vocabulary terms you'll be assessed on include stomata and adhesion.

Quiz & Worksheet Goals

Be sure to understand the definition and concepts of:

  • Rate of transpiration
  • Kinetic energy
  • Xylem
  • Evaporation
  • Cohesion

Skills Practiced

This quiz and worksheet will test the following skills:

  • Reading comprehension - ensure that you draw the most important information from the related lesson on transpiration and the way that water exits plants
  • Problem solving - use acquired knowledge to solve practice problems
  • Critical thinking - apply relevant concepts to examine information about how the number of stomata affects the rate of transpiraiton
  • Distinguishing differences - compare and contrast the way that different environmental conditions affect the rate of transpiration

Additional Learning

Check out the lesson on Transpiration Biology Lab to learn more. This lesson covers the following objectives:

  • Define capillary action and learn about properties of water
  • Differentiate between cohesion and adhesion
  • Understand how a potometer is used to measure the rate of transpiration
  • Understand what the acronym TACT stands for
