Transpiration: The Journey of Water Through Plants

The video tutorial explains plant transpiration, a process where plants absorb water through roots and release excess moisture into the air. This is demonstrated through an experiment using a plant, jar, and aluminum foil to observe moisture collection over time, illustrating transpiration's role in the water cycle.

What is the primary function of transpiration in plants?

• To attract pollinators

• To produce oxygen

• To release excess water into the atmosphere

• To absorb nutrients from the soil

Which part of the plant is primarily involved in transpiration?

• Flowers

• Leaves

• Stems

• Roots

What was used to prevent soil moisture from evaporating in the experiment?

• Aluminum foil

• Glass cover

• Plastic wrap

• Cloth

Why was aluminum foil chosen over plastic for the experiment?

• It is more durable

• It is cheaper

• It is easier to see on video

• It is more environmentally friendly

How often were observations made during the experiment?

• Every hour

• Every 30 minutes

• Every 20 minutes

• Every 10 minutes

What was observed on the sides of the jar during the experiment?

• Water vapor

• Plant roots

• Soil particles

• Insects

How long did it take to see significant moisture on the jar?

• 51 minutes

• 2 hours

• 32 minutes

• 10 minutes

What is the source of the moisture released by plants during transpiration?

• Rainwater

• Groundwater absorbed by roots

• Condensation

• Dew

What role does transpiration play in the water cycle?

• It reduces water pollution

• It helps in cloud formation

• It contributes to water evaporation

• It prevents soil erosion

What happens to the water absorbed by plant roots?

• It is stored in the roots

• It is used entirely for photosynthesis

• It is released into the atmosphere

• It is converted into nutrients
