Transpiration Flashcard

Front

What is transpiration in plants?

Back

Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as water vapor through stomata in leaves.

Front

What are stomata?

Back

Stomata are microscopic holes in leaves that open and close to regulate gas exchange and allow water to transpire.

Front

What role does the xylem play in plants?

Back

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

What happens to the weight of celery when it is left in water for a period of time?

Back

The celery weighs a little more after being left in water, but not as much as the amount of water that has evaporated.

Front

What does the control vial of water demonstrate in an experiment on transpiration?

Back

The control vial of water demonstrates how much water evaporates in a day, providing a baseline for comparison.

Front

Why is transpiration important for plants?

Back

Transpiration helps in nutrient uptake, cooling the plant, and maintaining turgor pressure.

Front

What factors can affect the rate of transpiration?

Back

Factors include temperature, humidity, wind speed, and light intensity.

Front

How does temperature influence transpiration rates?

Back

Higher temperatures increase the rate of transpiration by causing water to evaporate more quickly.

Front

What is the relationship between humidity and transpiration?

Back

Higher humidity levels decrease the rate of transpiration because the air is already saturated with moisture.

Front

What is turgor pressure and why is it important?

Back

Turgor pressure is the pressure of water inside plant cells that helps maintain structure and support; it is crucial for plant rigidity.
