Transpiration in plants

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 called stomata in the leaves.

Front

What are the main functions of transpiration?

Back

The main functions of transpiration are to transport water and mineral salts from the roots to the leaves, and to help regulate temperature and maintain plant structure.

Front

What do plants lose during transpiration?

Back

Plants lose water in the form of water vapor during transpiration.

Front

How does temperature affect the rate of transpiration?

Back

As the surrounding temperature increases, the rate of transpiration increases, causing plants to lose water faster.

Front

What is guttation?

Back

Guttation is the process of water loss from plants in liquid form through hydathodes, which are openings at the edges of leaves.

Front

What happens to transpiration rates in low light conditions?

Back

The rate of transpiration is lower when the light intensity is lower.

Front

What is the role of stomata in transpiration?

Back

Stomata are small openings on the surface of leaves that allow water vapor to escape during transpiration.

Front

What is the function of the waxy cuticle on leaves?

Back

The waxy cuticle reduces the loss of water from the plants by evaporation.

Front

What factors can affect the rate of transpiration?

Back

Factors that can affect the rate of transpiration include temperature, humidity, wind speed, and light intensity.

Front

How does humidity affect transpiration?

Back

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