question 13 (1 point)
what is the function of stomata?
o a cells that make chlorophyll
o b tubes that move water
o c barriers that prevent seed drying
o d openings that allow gas exchange

Explanation:

Stomata are small openings on the surface of plant leaves. Their main function is to facilitate gas exchange, allowing carbon dioxide to enter for photosynthesis and oxygen to exit. They also play a role in transpiration (water vapor release).

• Option a: Chlorophyll is made in chloroplasts within plant cells, not by stomata.
• Option b: Tubes that move water are xylem vessels, not stomata.
• Option c: Structures that prevent seed drying are related to seed coatings or other seed - specific adaptations, not stomata.
• Option d: Stomata are indeed openings that allow gas exchange (e.g., \(CO_2\) in, \(O_2\) out).

Answer:

d. Openings that allow gas exchange
