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.
The vascular tissue in seedless vascular plants, like ferns, is made up of long,tube like cells. These cells carry water, minerals, and food to the cells throughout the plant.Non vascular plants like the moss are usually only a few cells thick.Vascular plants, on the other hand, can grow larger and thicker because the vascular tissue distributes water and nutrients to all plant cells. Vascular tissue is used to transport nutrients from the base of the plant to throughout the organism.     That's the gist of it.     Here's how it works:  â¦    First off, plants don't move like animals.
