CENTRAL CYLINDER Meaning and
Definition
-
The term "central cylinder" refers to the specialized region found within the stems and roots of vascular plants. It is a crucial anatomical component that functions in conducting water, minerals, and other essential nutrients throughout the plant. The central cylinder is also known as the "stele" and serves as the main structural support system for the plant.
Within the central cylinder, several key tissues are present. The most significant tissue is the vascular tissue, which consists of two types: xylem and phloem. Xylem cells transport water and minerals from the roots to other areas of the plant, primarily through their hollowed-out vessels. In contrast, phloem cells transport organic nutrients, such as sugars, produced in the leaves to other parts of the plant.
The central cylinder also contains the endodermis, a specialized layer of cells that surround the vascular tissue. The endodermis helps regulate the movement of water and nutrients by acting as a selective barrier. Additionally, the central cylinder often houses the pericycle, a layer of cells responsible for lateral root formation, allowing the plant to expand its root system and increase nutrient uptake.
Overall, the central cylinder is a crucial component of the plant's structure and functionality, playing a vital role in nutrient transport, support, and root expansion.

Etymology of CENTRAL CYLINDER
The term "central cylinder" doesn't have a specific etymology on its own because it is a combination of two common English words. However, the word "central" and the word "cylinder" do have their own respective origins.
The word "central" comes from the Late Latin word "centralis", which means "of or pertaining to a center". It is derived from the Latin word "centrum", meaning "center", which ultimately comes from the Greek word "kéntron".
The word "cylinder" has its roots in the Latin word "cylindrus", which is derived from the Greek word "kulindros". It refers to a solid geometric shape with parallel circular bases and a curved surface.
Therefore, when these two words are combined, "central cylinder" refers to a cylinder that is centrally positioned or located at the center of something.
