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.
Let'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.It acts like roads and plumbing, moving around nutrients and water needed by the plant. There are two types of vascular tissue: xylem and phloem.Xylem transports water and dissolved minerals, while phloem transports food. Previously it was pointed out that an easy way to remember which vascular tissue is which is that 'phloem' and 'food' both start with the same sound.et's now look at some specialized types of vascular tissue found in plant stems that is surrounded by the ground tissue.
