Cork cells form a protective layer around plant stems.
epidermis
The Epidermis
It is not an organism. It is a layer of cells in the cortex of a root or some stems. As such it is a tissue.
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.
Yes. Stems do have cells.
The outer layer of roots and stems, called the epidermis, develops from the protoderm, which is one of the three primary meristems in plant growth. The protoderm gives rise to the outer protective layer of cells that covers the plant's surface.
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 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.
The outermost layer of cells that covers roots, stems, leaves, and flower parts is called the epidermis. The epidermis helps protect the plant from water loss, pathogens, and physical damage. It also plays a role in gas exchange and nutrient absorption.
cambium. and it doesnt just seperates between xylem and phloem, it creates them.
The periderm is the secondary protective (dermal) tissue that replaces the epidermis during growth in thickness of stems and roots of gymnosperms and dicotyledons (i.e., secondary growth). Unlike the epidermis, the periderm is a multilayered tissue system, the bulk of which usually constitutes the cork, or phellem.
