Lower epidermis allows for gas exchange- due to presence of guard cells and stomata 3. Vascular tissue provides support - strong xylem tubes keep plant erect 4. epidermis provides for water conservation by cuticle production and ability to close stomates. 5. Vascular tissue= system of tubes = water transport 6. Vascular tissue = sugar and product transport, particularly phloem tissue
