Transpiration in Plants Quiz

What is the primary function of stomata in plants?

• To produce chlorophyll

• To facilitate water loss

• To absorb sunlight

• To store nutrients

Which part of the stomata is responsible for opening and closing?

• Mesophyll cells

• Xylem vessels

• Guard cells

• Epidermal cells

What process describes the movement of water from a high to a low concentration in plants?

• Osmosis

• Transpiration

• Photosynthesis

• Diffusion

In a potometer experiment, why is it important to cut the stem under water?

• To prevent air from entering the stem

• To reduce water loss

• To increase the surface area

• To enhance photosynthesis

What is the purpose of using vaseline in a potometer setup?

• To prevent air leaks
