Transport in plants

Front

What is transpiration in plants?

Back

Transpiration is the process by which water vapor is released from the plant's leaves into the atmosphere, primarily through small openings called stomata.

Front

How does light intensity affect the transpiration rate?

Back

As light intensity increases, the transpiration rate also increases due to the opening of stomata for photosynthesis.

Front

What part of the plant is primarily responsible for water absorption?

Back

Roots are primarily responsible for absorbing water from the soil.

Front

What is the function of xylem in plants?

Back

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

Front

What is the function of phloem in plants?

Back

Phloem is responsible for transporting sugars and nutrients produced during photosynthesis from the leaves to other parts of the plant.

Front

Define osmosis in the context of plant transport.

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is diffusion in plants?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration, such as the movement of gases in and out of leaves.

Front

What direction do water and minerals move within the plant?

Back

Water and minerals move upward within the plant, from the roots to the leaves.

Front

What is the role of stomata in plant transport?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange and the release of water vapor during transpiration.

Front

What factors can affect the rate of transpiration?

Back

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