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.
The outermost layer of a root is called the epidermis. It is a single layer of cells that protects and covers the root. In stems and leaves, the outermost layer is also called the epidermis, and it serves a similar protective function.
They have woody stems
Protective tissues in plant bodies are typically found in the epidermis, which is the outermost layer of cells. The epidermis is responsible for protecting the plant from physical damage, pathogens, and water loss. In woody plants, the outermost layer of the stem and roots is covered by a thick layer of protective tissue called the periderm, which replaces the epidermis in older parts of the plant.
The Epidermis
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.
Gymnosperms have woody stems, which are typically covered in a thick layer of protective bark. The stems of gymnosperms also often contain vascular tissues for water and nutrient transport.
No, the water lotus does not have a woody stem. It has a fleshy rhizome from which stems arise, but these stems are not woody.
Non-woody stems are called herbaceous plants. (Hur~Ba~Shus)
There are different kinds of stems some are woody and some are non-woody. Woody stems have alote of xylem tissue. Trees and shrubs have woody stems. The woody of conifers such as pine tree is soft wood.
No, herbaceous stems are typically soft and flexible, unlike woody stems which are hard and rigid. Herbaceous stems lack a true outer bark layer and are mainly composed of cells that allow for growth and flexibility.
No, their stems are green and quiet flexible, not woody.
