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.
Non-vascular plants such as mosses donât have vascular tissue, but in all other plants xylem transports water around the plant. Xylem cells are like zombies in that they are dead when functional. They donât, however, eat brains.At least, not that we know of.issues that make up part of the plant but are not vascular tissue or epidermis are called ground tissue. Ground tissue can be found inside and outside the ring of vascular tissue in the plant stem.
