Transpiration Rate Experiment Quiz

Which of the following is NOT a material required for the transpiration experiment?

• Filter paper strips

• 3% cobalt chloride solution

• Glass slides

• Bunsen burner

What is the purpose of dipping filter paper strips into the cobalt chloride solution?

• To make them waterproof

• To change their color to blue

• To sterilize them

• To prepare them for measuring transpiration

How long should the filter paper strips be left in the cobalt chloride solution?

• 10 to 15 minutes

• 3 to 5 minutes

• 20 to 25 minutes

• 1 to 2 minutes

What observation is made after 15 minutes regarding the cobalt chloride paper on the leaf surfaces?

• Both surfaces turn completely blue

• Both surfaces remain unchanged

• The lower surface turns pink faster than the upper surface

• The upper surface turns pink faster than the lower surface

What conclusion can be drawn from the experiment about the rate of transpiration?

• Both surfaces have the same rate of transpiration

• The lower surface has a higher rate of transpiration

• Transpiration does not occur in leaves

• The upper surface has a higher rate of transpiration
