Transport in Plants

Question 1

What do xylem vessels do?

Answer 1

Transport water and minerals from the roots to the stem and leaves.

Question 2

What do phloem vessels do?

Answer 2

Transports food materials (mainly sucrose and amino acids) made by the plant from photosynthesising leaves to non-photosynthesising regions in the roots and stem.

Question 3

Where are xylem vessels and phloem vessels arranged?

Answer 3

These vessels are arranged throughout the root, stem and leaves in groups called vascular bundles.

Question 4

Why does water enter the root hair cells by osmosis?

Answer 4

This happens because soil water has a higher potential than the cytoplasm of the root hair cell.
