stomata

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange between the plant and the environment.

Front

What is the primary function of stomata in plants?

Back

The primary function of stomata is to allow for gas exchange, specifically the intake of carbon dioxide and the release of oxygen.

Front

How do stomata contribute to photosynthesis?

Back

Stomata are essential for photosynthesis as they allow carbon dioxide to enter the leaf, which is necessary for the process.

Front

What is the relationship between stomata and transpiration?

Back

Stomata play a crucial role in transpiration by regulating the loss of water vapor from the plant to the atmosphere.

Front

What factors influence the opening and closing of stomata?

Back

Factors include light intensity, humidity, temperature, and the availability of water.

Front

What happens to stomata during high temperatures?

Back

During high temperatures, stomata tend to close to reduce water loss.

Front

What is the role of guard cells in relation to stomata?

Back

Guard cells surround each stoma and control its opening and closing, thus regulating gas exchange and water loss.

Front

What is cohesion in the context of water and stomata?

Back

Cohesion refers to the attraction between water molecules, which helps in the movement of water through the plant's xylem.

Front

What is adhesion in the context of water and stomata?

Back

Adhesion is the attraction between water molecules and the walls of the xylem vessels, aiding in the upward movement of water.

Front

How do stomata affect plant respiration?

Back

Stomata allow oxygen to exit and carbon dioxide to enter, which are essential for cellular respiration in plants.
