Worked practice questions

What is transpiration?

  1. Mineral production in leaves
  2. Root storage of water
  3. Water movement and evaporation
  4. Sugar release from plant roots
Show answer and solution

Correct answer: C. Water movement and evaporation

Transpiration is water movement through a plant followed by evaporation from aerial parts.

From which plant parts does transpiration occur?

  1. Aerial plant parts
  2. Root regions
  3. Belowground stems
  4. Seed surfaces
Show answer and solution

Correct answer: A. Aerial plant parts

Transpiration evaporates water from aerial parts such as leaves and stems.

Does transpiration directly require energy from the plant?

  1. Yes, it uses ATP
  2. Only at night
  3. No, it is passive
  4. Only in roots
Show answer and solution

Correct answer: C. No, it is passive

Transpiration is described as a passive process needing no energy expense.
