Transport in Plants Flashcards
1
Q
What do xylem vessels do?
A
Transport water and minerals from the roots to the stem and leaves.
2
Q
What do phloem vessels do?
A
Transports food materials (mainly sucrose and amino acids) made by the plant from photosynthesising leaves to non-photosynthesising regions in the roots and stem.
3
Q
Where are xylem vessels and phloem vessels arranged?
A
These vessels are arranged throughout the root, stem and leaves in groups called vascular bundles.
4
Q
Why does water enter the root hair cells by osmosis?
A
This happens because soil water has a higher potential than the cytoplasm of the root hair cell.
