Plant Transpiration

What is the primary process through which roots absorb water?

• Evaporation

• Photosynthesis

• Osmosis

• Diffusion

In the transpiration experiment, why do water droplets appear inside bag A?

• Condensation of water vapor from the leaves

• Condensation from the air

What does cobalt chloride paper indicate when it turns pink?

• Presence of sunlight

• Presence of water

• Absence of water

• Presence of minerals

Why is transpiration more on the underside of leaves?

• Less water on the underside
