2.3.3 Factors Affecting Transpiration

• Water in plants is lost through small pores called stomata
• What is the process of transpiration in plants?

  Evaporation of water
• Higher temperatures increase the rate of transpiration


  True
• Higher wind speed increases the rate of transpiration
• What is the role of stomata in transpiration?

  Water vapor release
• Order the steps of water movement in transpiration:

  1️⃣ Water is absorbed by the roots

  2️⃣ Water is transported through the plant

  3️⃣ Water evaporates from the leaves

  4️⃣ Water vapor escapes through stomata
• The higher the number of open stomata, the higher the rate of transpiration


  True
• When light intensity increases, guard cells are triggered to open the stomata
• As temperature increases, the rate of transpiration also increases
• Transpiration involves the evaporation of water from the leaves of a plant through the stomata.


  True
• When light intensity increases, guard cells open the stomata
• High humidity reduces the rate of transpiration in plants.


  True
• How does wind speed affect the concentration gradient near the leaf surface?

  Increases the gradient
• Abundant water availability leads to high transpiration and open stomata.


  True
• How does higher humidity affect the rate of transpiration?

  It decreases the rate
• The stomata are located on the roots of plants

  False
• Higher wind speed increases the evaporation of water vapor, which in turn increases the rate of transpiration
• How does light intensity affect the opening of stomata?

  Higher opens stomata
• What triggers guard cells to open the stomata in plants?

  Increased light intensity
• Why does increased light intensity lead to a higher rate of transpiration?

  Stomata open wider
• Why does higher temperature increase the rate of transpiration?

  More kinetic energy of water molecules
• What are stomata and their primary role in transpiration?

  Small pores on leaf surface
• What happens to the kinetic energy of water molecules as temperature increases?

  Increases
• Higher humidity decreases the rate of transpiration in plants.
• What happens to transpiration when water availability is limited?

  Stomata close
• What is the process of transpiration in plants?

  Evaporation of water
• Higher temperatures increase the rate of transpiration.


  True
• Higher wind speed increases the rate of transpiration.
• What are stomata, and where are they located?

  Small pores on leaves
• Guard cells open the stomata when light intensity increases.


  True
• What is the effect of increased light intensity on transpiration?

  Increases transpiration
• Why does higher temperature increase transpiration?

  More kinetic energy
• Why does high humidity reduce transpiration rates?

  Reduces water vapor gradient
• What happens to transpiration when water availability is limited?

  Decreases due to closed stomata
• Water is absorbed by the roots, transported through the plant, and lost through the stomata
• What effect does higher humidity have on transpiration?

  Decreases it
• How does light intensity affect transpiration rates?

  Increases it
• Stomata allow water vapor to escape from the leaf, creating a driving force for water movement from the roots.
• Higher stomatal opening leads to a higher rate of transpiration.
• Higher temperatures increase the rate of transpiration.
