What are the six layers of a young woody stem?
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.
The outermost layer consisting of ground tissue in a stem is called what?
The outermost layer of ground tissue in a stem is called the cortex. It helps protect the inner layers of the stem and provides structural support.
Which organ do stem cells start differentiating to form a few weeks after conception?
Stem cells in the early embryo start differentiating to form the three primary germ layers - ectoderm, mesoderm, and endoderm. These layers give rise to all the tissues and organs in the body.
List in order the layers of tissue within a woody stem moving from the center of the stem to the outermost layer?
The layers of tissue within a woody stem, from the center to the outermost layer, are as follows: the pith, which is the central storage tissue; the xylem, responsible for water and nutrient transport; the cambium, a layer of actively dividing cells that facilitate growth; the phloem, which transports sugars; and finally, the bark, the protective outer layer.
What in order list in order the layers of tissue within a woody stem?
The layers of tissue in a woody stem, from the outermost to the innermost, are: the bark (which includes the protective outer layer and the phloem), the cambium (a thin layer of actively dividing cells), the xylem (which consists of heartwood and sapwood), and the pith at the center. The bark serves to protect the stem, the cambium is responsible for secondary growth, the xylem conducts water and nutrients, and the pith stores nutrients.
The inner layers of ground tissue in a stem?
pith

What is a pluripotent cell?
A stem cell that can differentiate into any cell (tissue) of the three germ layers.

Stem cells in the early embryo start differentiating to form the three primary germ layers - ectoderm, mesoderm, and endoderm. These layers give rise to all the tissues and organs in the body.
The rough outer layer of the woody stem is called?
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.

What term describes the kind of stem cell that can grow into all cell types in the body?
The term that describes stem cells capable of developing into all cell types in the body is "pluripotent stem cells." These cells can differentiate into nearly any cell type, including those from all three germ layers: ectoderm, mesoderm, and endoderm. An example of pluripotent stem cells is embryonic stem cells, which are derived from early-stage embryos.
Does pine tress have woody stem or soft stem?
Pine trees have a woody stem. The stem of a pine tree is characterized by its strong, sturdy structure, which allows the tree to support its height and weight. The woody stem is composed of layers of xylem and phloem tissues that provide structural support and transport water, nutrients, and sugars throughout the tree.
Is a pine tree a woody stem?
Yes, a pine tree has a woody stem. Woody stems are characterized by their hard, rigid structure, which allows trees like pines to grow tall and support their branches and leaves. In pines, the stem is composed of layers of bark, cambium, and wood, contributing to the tree's overall strength and stability.
What does the stem do for the stem?
Cambium, in plants can be defined as layers of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots. Secondary growth can be defined as occurring after the first season and results in increase in thickness
