-Phloem.
2
Q
What are the ‘Xylem’?
A
Transport Water & Mineral Ions from the Roots to the Stem & Leaves.
3
Q
Explain the Structure of the Xylem.
A
It is Composed of Hollow Tubes Strengthened by Lignin Adapted for the Transport of Water in the Transpiration Stream.
4
Q
What are the ‘Phloem’?
A
Transport Dissolved Sugars from P.sis. in the Leaves to Around the Plant for Growth & Repairing Plant Cells.

Osmosis.
6
Q
How do Root Hair Cells Intake Mineral Ions from the Soil?
A
Active Transport.
7
Q
How are Root Hair Cells Adapted to their Functions?
