Transpiration Flashcard

Front

What is transpiration?

Back

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

Front

What are stomata?

Back

Stomata are microscopic holes in the leaves of plants that open and close to regulate the exchange of gases and the release of water vapor during transpiration.

Front

Why is transpiration important for plants?

Back

Transpiration helps in nutrient uptake, cooling the plant, and maintaining the flow of water and nutrients from the roots to the leaves.

Front

What happens to the water level when celery is placed in water?

Back

The water level drops significantly because the celery absorbs the water through its stem.

Front

How does water leave the plant?

Back

Water leaves the plant primarily through transpiration, which occurs at the leaves.

Front

What is the role of roots in transpiration?

Back

Roots absorb water from the soil, which is then transported through the plant to the leaves.

Front

What is the correct order of water movement in transpiration?

Back

The correct order is: Roots → Stem → Stomata.

Front

What are the main factors affecting the rate of transpiration?

Back

The main factors include temperature, humidity, wind speed, and light intensity.

Front

How do plants regulate transpiration?

Back

Plants regulate transpiration by opening and closing their stomata in response to environmental conditions.

Front

What is the difference between transpiration and evaporation?

Back

Transpiration is the release of water vapor from plants, while evaporation is the process of water turning into vapor from any surface.
