6.3.2 Transpiration

• Lower humidity enhances transpiration.


  True
• Match the factor with its effect on transpiration:

  Temperature ↔️ Increases evaporation

  Humidity ↔️ Decreases evaporation

  Light Intensity ↔️ Opens stomata

  Wind Speed ↔️ Removes moisture
• Roots absorb water from the soil
• Water travels from the roots to the leaves through the xylem.

  True
• Where does water evaporate from during transpiration?

  Stomata
• Water evaporates from leaves through stomata.

  True
• Lower humidity allows more water to evaporate
• Transpiration facilitates the transport of water and dissolved minerals
• Transpiration is the process where water evaporates from the leaves
• More light causes stomata to open
• Transpiration facilitates the transport of water and minerals in plants.

  True
• What is the function of xylem in transpiration?

  Transport water and minerals
• Which structure absorbs water from the soil in plants?

  Roots
• How does higher temperature affect the rate of transpiration?

  Increases evaporation rates
• What is the role of wind in transpiration?

  Increases evaporation
• What is the role of roots in transpiration?

  Absorb water from soil
• What are stomata and their role in transpiration?

  Pores that release water vapor
• Water is absorbed by the roots
• Steps in the transpiration process

  1️⃣ Roots absorb water from the soil

  2️⃣ Water travels up the xylem vessels

  3️⃣ Water evaporates through stomata
• Higher temperatures speed up the rate of evaporation
• Transpiration helps cool the plant and facilitates the transport of water and minerals
• Stomata are tiny pores on the leaf surface that allow water vapor to exit
• Transpiration helps cool the plant by water evaporation.


  True
• Transpiration rate refers to the amount of water lost by a plant through transpiration
• Roots are responsible for absorbing water from the soil
• Transpiration drives the uptake of essential nutrients from the soil
• The weighing method measures water loss by comparing the plant's weight before and after
• Transpiration is the process where water evaporates from the leaves of plants
• Match the factor with its effect on transpiration:

  Temperature ↔️ Increases evaporation rate

  Humidity ↔️ Decreases evaporation rate

  Light Intensity ↔️ Opens stomata for more water loss

  Wind Speed ↔️ Removes moist air, enhancing evaporation
• Transpiration helps cool the plant by evaporation.


  True
• Nutrient uptake is driven by the flow of water through the plant.


  True
• The xylem transports water and minerals upward in the plant.


  True
• Main steps in the transpiration process

  1️⃣ Water is absorbed by roots

  2️⃣ Water travels up the xylem

  3️⃣ Water evaporates through stomata
• Match the plant adaptation with its effect on transpiration:

  Thick Cuticle ↔️ Reduces water evaporation

  Small Leaves ↔️ Decrease surface area for evaporation

  Sunken Stomata ↔️ Lower humidity around stomata

  Hairy Leaves ↔️ Trap moisture near leaf surface
• Transpiration rate is affected by environmental factors like temperature and humidity.
