stomata

Front

What are stomata?

Back

Stomata are tiny openings on the surface of leaves that allow for gas exchange, primarily oxygen and carbon dioxide.

Front

What are guard cells?

Back

Guard cells are specialized cells that surround each stoma and control its opening and closing.

Front

What is transpiration?

Back

Transpiration is the process of water vapor diffusing out of a leaf through the stomata.

Front

How do stomata respond to high temperatures?

Back

During higher temperatures, leaves will have fewer stomata to reduce water loss.

Front

What is the role of stomata in photosynthesis?

Back

Stomata allow carbon dioxide to enter the leaf, which is essential for photosynthesis.

Front

What is the relationship between stomata and water loss?

Back

Stomata facilitate water loss through transpiration, which helps in nutrient uptake and temperature regulation.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows water molecules to stick together, which is important for capillary action.

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to stick to other surfaces, such as the walls of xylem vessels.

Front

What is the function of xylem?

Back

Xylem is responsible for transporting water and dissolved minerals from the roots to the rest of the plant.

Front

What is the function of phloem?

Back

Phloem transports sugars and other metabolic products downward from the leaves.
