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.
Phloem and xylem are the two main types of vascular tissue found in plants. Xylem is the tissue that mainly carries water, and a few minerals, in the system.Phloem is the tis â¦ sue that carries photosynthetic materials through the plant.ne kind of vascular tissue is called the xylem and is responsible for the upward transport of nutrients and water. Another is phloem which is responsible for the downward tra â¦ nsport of photosynthates, plant hormones and other control substances. + 15 others found this useful. Tina Hunt.
