Transpiration Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is transpiration in plants?

Transpiration is the process in which water absorbed by the roots evaporates from the surface of the leaves.

What is a transpiration stream?

A transpiration stream is the steady movement of water through the xylem, driven by transpiration, which helps transport water against gravity.

Name two functions of transpiration besides water movement.

Transpiration keeps cells turgid to support plant structure and provides water for photosynthesis.

What role do stomata play in plants?

Stomata are tiny holes in the leaf’s surface that control gas exchange and are involved in water evaporation from the leaves.

How do guard cells regulate the size of stomata?

Guard cells become plump and turgid in the day, opening stomata, and become flaccid in low light, closing stomata.

Why do plants have more stomata on the underside of leaves?

To minimize water loss by evaporation, as the lower surface is shaded and cooler.
