The rough outer layer of the woody stem is called bark. Bark acts as a protective barrier for the inner layers of the stem, helping to prevent damage from physical elements and pathogens.
The inner bark of a woody stem is composed of living tissue called the phloem, which transports nutrients produced through photosynthesis from the leaves to the rest of the plant. It is located just outside the cambium layer, which is responsible for producing new layers of phloem and xylem. The inner bark plays a crucial role in the overall health and growth of the plant.
The openings in the bark of woody plants that allow gas exchange are called lenticels. They are small, porous structures that facilitate the exchange of oxygen and carbon dioxide between the internal tissues of the plant and the external environment, helping to maintain proper cellular respiration.
Tree bark thickness varies depending on the type of tree, with some species having thin bark of only a few millimeters, while others may have bark that is several inches thick. Typically, the outer bark layer is thinner, while inner layers can be thicker and more protective.
Trees can get bark through a process called secondary growth, where they produce new tissue underneath the bark. The bark serves as a protective outer layer against pests, diseases, and environmental stressors. As the tree grows, the bark expands and gets thicker to accommodate the increasing size of the tree.
All dicots are woody if that is what you mean. Monocots are not woody so you will never see bark on a monocot.
The tissue that divides the bark from the wood in woody stems is called the vascular cambium. It is a layer of meristematic tissue that is responsible for secondary growth, producing new xylem (wood) and phloem (inner bark) cells.
The bark is useful by protecting the tree from "injury" and repelling diseases.
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.

They are fairly woody/bark-like in texture when dry.
The rough outer layer of the woody stem is called the bark. It serves to protect the inner tissues of the stem from damage caused by pests, diseases, and environmental factors.

The six layers of a young woody stem, from outermost to innermost, are the bark, cork cambium, cork, secondary phloem, vascular cambium, and secondary xylem. These layers provide structural support, transport nutrients and water, and protect the inner tissues of the stem.
A tree bark can be best described as tissues on a woody stem or root outside the vascular cambium.
