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.
Vascular tissue Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the â¦ xylem and phloem. These two tissues transport fluid and nutrients internally. 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. For example, humans can pick up their nutrients (food/water, etc.) with their hands.
