The answer is the vascular cambium that divides the bark from the wood in woody stems.

The two kinds of stems are- 1.Herbaceous stems-They do not have developed ligneous structures. They are generally frail 2.Ligneous stems-They have developed rigid, stiffened structures, what we normally know as "wood".
Yes. As you can see, herbaceous stems are soft and green while woody stems are thick, hard and woody. Stems can be of several sorts, herbaceous and woody. The herbaceous stems are green and fairly bendable. The woody stems as their name implies, are covered by bark. The herbaceous stem has more pith for its size. The cambium which causes woody stems to get bigger in width is not as active in the herbaceous stems. Most herbaceous plants are annuals or planted yearly. The herbaceous stem has little notches where leaves develop. Woody stems have scars where twigs and fruit have dropped off and little openings for transpiration.

All dicots are woody if that is what you mean. Monocots are not woody so you will never see bark on a monocot.

The bark is useful by protecting the tree from "injury" and repelling diseases.

Periderm, also known as bark is the outermost layer of stems and roots of woody plants.
Yes, bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines and shrubs. Bark refers to all the tissues outside of the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost area of the periderm. The outer bark in older stems, includes the dead tissue on the surface of the stems, along with parts of the innermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees is also called the rhytidome. Products used by people that are derived from bark include: spices and other flavorings, tannin, resin, drugs, latex,poisons, various hallucinatory chemicals and cork. Bark has been used to make cloths, canoes, ropes and used as a surface for paintings and map making. A number of plants are also grown for their attractive or interesting bark colorations and surface textures or their bark is used as landscape mulch.

Yes, weeds have bark if they're nuisance shrubs, trees or woody vines. Bark refers to the outer covering of roots and stems in woody plants such as woody vines, trees and shrubs. Weeds refer to plants that grow where they aren't wanted or to plants whose usefulness is unknown or negated by their harmfulness. Therefore, a weed has bark when it's a question of a shrub, tree or woody vine growing where you don't want it or where it's causing harm to the environment.
Bark as a noun1. Tough protective covering of the woody stems and roots of trees and other woody plants2. The sound made by a dog3. A noise resembling the bark of a dog4. A sailing ship with 3 (or more) masts Bark as a Verb1. Speak in an unfriendly tone2. Cover with bark3. Remove the bark of a tree4. Make barking sounds5. Tan (a skin) with bark tannins
Stem - supporting structure of a plant, serving also to conduct and to store food materials. The stems of herbaceous and of woody plants differ: those of herbaceous plants are usually green and pliant and are covered by a thin epidermis instead of by the bark of woody plants. There is relatively more pith in herbaceous stems, and the cambium, which increases the diameter of woody stems, is usually almost inactive; it is therefore characteristic of herbaceous stems that, although they increase in height, their increase in diameter is small.
All dicots are woody if that is what you mean. Monocots are not woody so you will never see bark on a monocot.
Bark beetles are examples of insects that destroy plants.Specifically, a bark beetle gets under the outer protective bark of a woody plant. Bark beetles therefore manage to access a shrub's or tree's dead and living tissue. That access spells the beginning of the end for the woody plant in question since detection often occurs too late for appropriate treatment.
