Transpiration

The video explains the process of water vapor loss from plants to the atmosphere, primarily through transpiration from leaves. It highlights the role of stomata in allowing water vapor to escape and describes how this loss creates a suction effect that helps move water from the roots against gravity.

What is the process called where water vapor is lost from plants to the atmosphere?

• Evaporation

• Condensation

• Precipitation

• Transpiration

Where does transpiration mainly occur in plants?

• Stems

• Roots

• Flowers

• Leaves

What are the tiny holes on the surface of leaves called?

• Chloroplasts

• Vacuoles

• Stomata

• Pores

How does water vapor escape from the leaves?

• Through the flowers

• Through the roots

• Through the stem

• Through stomata

What effect does the loss of water through transpiration have on water movement in plants?

• It creates a suction effect

• It creates a magnetic effect

• It creates a pressure effect

• It creates a gravitational effect
