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

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.

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.
