Which stem tissue is the oldest band of xylem found?
The oldest band of xylem in a stem tissue is typically found in the center of the stem, forming the heartwood. This is the most inner part of the stem where xylem cells have become non-functional and filled with resins, tannins, and other substances that make the wood hard and durable.
How do satellite cells differ from stem cells in terms of their function and role in tissue regeneration?
Satellite cells are a type of stem cell that specifically help repair and regenerate muscle tissue. Stem cells, on the other hand, have the ability to develop into different types of cells in the body. While both satellite cells and stem cells play a role in tissue regeneration, satellite cells are more specialized and focused on repairing muscle tissue.
Difference between monocotyledon and dicotyledon in stem?
1. at monocot stem. -stem hairs are absent. -sclerenchyma hypodermis. -internal tissue is not differentiated into different concentric layer but there is a common mass called ground tissue. -vascular bundles is found scattered in ground tissue. -presence of water cavity. 2. at dicot stem -stem hairs are present. -collenchyma hypodermis. -internal tissue is differentiated into hypodermis, cortex, endodermis, pericycle, medullary ray and pith. -vascular bundle is found between preicycle and pith. -water cavity is absent.
What is the difference between the arrangement of vascular tissue in the stems of dicots and monocots?
In young dicot and monocot stems do not increase in thickness. Xylem and phloem are arranged in vascular bundles in the cortex. In older stems and all woody stems, the vascular tissues form a cylinder between the cortex and the pith. The vascular bundles in a monocot are scattered throughout the stem.
What tissue occupies the center of the dicot stem?
cortex- In dicot stems, the cortex is located in the area between thevascular bundles and the epidermis. In monocot stems, it occupies the area surrounding the vascularbundles. The center of the stem is pith and may function as storage.
Dead cells which remain at the center of the stem are called?

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.
Which stem tissue is the oldest band of xylem found?
The oldest band of xylem in a stem tissue is typically found in the center of the stem, forming the heartwood. This is the most inner part of the stem where xylem cells have become non-functional and filled with resins, tannins, and other substances that make the wood hard and durable.
How many different types of tissue stem cells are there?
There are three different types of tissue stem cells in the body. They include the tissue stem cells also known as adult stem cells, embryonic stem cells, and induced pluripotent stem cells.
Which tissue contains xylem tissue?
The Stem
Growth tissue between xylem and phloem that produces additional xylem and phloem cells?
The dark center of a stem or root that is dead
What is the central part of a stem called?
The central part of a stem is called the pith. The pith is a spongy tissue located at the center of the stem, surrounded by the vascular tissues. It helps provide structural support and storage for nutrients in some plants.
What is the tissue that is commonly found on the stem of a plant?
Vascular tissue
What occupies the center of a plant cell?
A Vacuole
What is the center of roots called?
the stem
