Transpiration Quiz

What is transpiration?

• The loss of water vapour from the parts of the plant that are above ground

• The process of photosynthesis in plants

• The absorption of nutrients from the soil

• The growth of new leaves and stems

Through which part of the plant does water primarily move during transpiration?

• Stomata

• Root hair cells

• Xylem vessels

• Phloem vessels

What creates a large surface area for evaporation in leaves?

• The number of root hair cells

• The thickness of the leaf cuticle

• The presence of chlorophyll

• The many interconnecting air spaces between the mesophyll cells and the stomata

What is the main function of transpiration in plants?

• Transporting mineral ions

• Producing flowers

• Releasing oxygen

• Absorbing sunlight

What happens to water molecules in the xylem during transpiration?

• They break down into hydrogen and oxygen

• They form a continuous unbroken column due to cohesion

• They are stored in the roots

• They are converted into glucose

Which process helps to cool the plant down during transpiration?

• Absorption of sunlight

• Evaporation of water

• Photosynthesis

• Respiration

What is one of the effects of increased transpiration rate?

• Slower water uptake

• Increased leaf growth

• Decreased mineral absorption

• Faster water uptake

Which part of the plant is primarily responsible for water loss during transpiration?

• Stem

• Flowers

• Leaves

• Roots

What is the role of stomata in transpiration?

• Releasing water vapour

• Absorbing nutrients

• Storing water

• Producing chlorophyll

What is the primary reason for water moving up the xylem vessels?

• Gravity

• Transpiration pull

• Nutrient absorption

• Photosynthesis
