For example, a peripheral neuropathy caused by a vitamin deficiency can be treated -- even reversed -- with vitamin therapy and an improved diet. Likewise, nerve damage brought on by alcohol abuse can often be stopped and improved by avoiding alcohol.
2. Vascular tissue - xylem and phloem in leaves form in strands called veins. Xylem forms on the upper side of a vein (on a vertical leaf, on the side next to the stem), and phloem on the lower side (side away from the stem). a. Veins are like a leaf's fingerprint and can be used to identify plants.
Both monocots and dicots form different leaves. Monocot leaves are characterized by their parallel veins, while dicots form âbranching veins.â. Leaves are another important structure of the plant because they are in charge of feeding the plant and carrying out the process of photosynthesis.
