Biology 2.4.2 Flashcards
Plants Contain 2 Types of Transport Vessel: (2)
-Xylem.
-Phloem.
What are the ‘Xylem’?
Transport Water & Mineral Ions from the Roots to the Stem & Leaves.
Explain the Structure of the Xylem.
It is Composed of Hollow Tubes Strengthened by Lignin Adapted for the Transport of Water in the Transpiration Stream.
What are the ‘Phloem’?
Transport Dissolved Sugars from P.sis. in the Leaves to Around the Plant for Growth & Repairing Plant Cells.
How do Root Hair Cells Intake Water from the Soil?
Osmosis.
How do Root Hair Cells Intake Mineral Ions from the Soil?
Active Transport.
How are Root Hair Cells Adapted to their Functions?
Permanent Vacuole for Increased SA:V; makes Osmosis & Active Transport easier.
