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.
There are two types of vascular tissue: xylem, which moves water, and phloem, which moves food. These structures are arranged differently in monocots and dicots. In monocots, which are flowering plants with only one seed leaf, the xylem and phloem are found in paired bundles throughout the stem.et's now look at some specialized types of vascular tissue found in plant stems that is surrounded by the ground tissue. Previously, the concept of vascular tissue was addressed. Remember that vascular tissue is the tissue used to transport water and nutrients throughout a plant.
