IGBio 8.1&8.2 Transport in Plants: Xylem and Phloem

Front

How does water enter a plant?

Back

Water enters a plant by osmosis in root hair cells.

Front

What is it called when water sticks to water?

Back

Cohesion.

Front

What are xylem tubes made of?

Back

Xylem tubes are made of dead cells.

Front

What are phloem tubes made of?

Back

Phloem tubes are made of living cells.

Front

What part of the plant collects water?

Back

Roots.

Front

What is the primary function of xylem?

Back

The primary function of xylem is to transport water and minerals from the roots to the rest of the plant.

Front

What is the primary function of phloem?

Back

The primary function of phloem is to transport sugars and nutrients produced by photosynthesis from the leaves to other parts of the plant.

Front

What is adhesion in the context of plant transport?

Back

Adhesion is the attraction between water molecules and other substances, such as the walls of xylem vessels.

Front

What is capillary action?

Back

Capillary action is the ability of water to move upward through narrow spaces, such as xylem tubes, due to cohesion and adhesion.

Front

What role do root hair cells play in water absorption?

Back

Root hair cells increase the surface area for absorption and facilitate the uptake of water by osmosis.
