Ferns
­ Have vascular tissue ( a type of plant tissue specialized to conduct water and nutrients throughout the plant). January 10, 2017
• Cells walls have lignin makes the cell wall rigid, and together with the transport system, allows plants to reach great heights.
Vascular tissue can move fluids through the plant body, even against the force of gravity.
Two types of vascular tissue:
1) Xylem ­ carries water upward from the roots
2) Phloem ­ transports solutions of
nutrients and carbohydrates
