It is common, however, to encounter patients with vitamin B12 deficiency who have atypical clinical or laboratory features.
Nutrient, Liquid and Energy Distribution. Most of the advantages of vascular tissues stem from this functional one: A tracheophyte's xylem and phloem--which comprise the vascular system and are housed in the stem--enable liquids, nutrients and energy to be transported and distributed throughout the whole of the plant.
Best Answer: Vascular plants have lignified tissues that gives them physical support. Lignin gives the hard surface of plants that let them grow taller than nonvascular plants.Vascular plants also have vascular tissues: xylem and phloem that transport nutrients from roots to shoots and vice versa.While non-vascular plants don't have tissues that transport nutrients from and to different parts of the plant.

Therefore, they can grow quite tall and still all cells can obtain water and nutrients.
