Pernicious Anemia. Macrocytic anemia, glossitis, peripheral neuropathy, weakness, hyperreflexia, ataxia, and other neurological manifestations characterize classical vitamin B12 (cobalamin) deficiency. 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.
Making the world better, one answer at a time. The vascular system in plants have two components: xylem and pholem. The xylem helps in the transport of water absorbed through roots to all the aerial parts of the plant and the phloem helps in transporting the manufactured food from leaves to all other parts of the plant.he function of vascular tissue in plants is to carry and deliver nutrients,water and minerals through out the plant.
