Pronunciation: [ˈɛndə͡ʊdəmˌɪs] (IPA)

The word "Endodermis" (pronounced [ˌɛndoʊˈdɜrmɪs]) is a term used in biology to describe the inner layer of cells in a plant's root cortex. The spelling of "Endodermis" is derived from two Greek roots: endo- meaning "within" and derma meaning "skin". The IPA phonetic transcription breaks down the pronunciation of the word into its individual sounds, including the syllables "en", "do", "der", and "mis".

ENDODERMIS Meaning and Definition

  1. The endodermis is a specialized tissue found in the roots and stems of vascular plants. It forms the innermost layer of the cortex in these organs and serves as a selective barrier for the movement of water and nutrients. The name "endodermis" originates from the Greek words "endo," meaning inner, and "derma," meaning skin, highlighting its position as the innermost layer.

    In roots, the endodermis comprises a single layer of tightly packed cells, with each cell having a distinct inner region known as the Casparian strip. This strip is characterized by the presence of a band made of suberin, a waxy substance that prevents the passage of water and solutes. As a result, all materials that penetrate the roots must pass through the endodermal cells via transport proteins.

    In stems, the endodermis plays a similar role, regulating the movement of substances between the outer tissues and the center of the stem. This is particularly important in woody plants, where the endodermis acts as a protective layer, preventing the ingress of pathogens or damaging substances.

    Overall, the endodermis acts as a gatekeeper for the plant, ensuring that nutrients and water are absorbed in an efficient and controlled manner. Its specialized structure and function make it a vital component of plant anatomy and physiology.

  2. In botany, the bundle-sheath enclosing the vascular bundles of stems and leaves.

Common Misspellings for ENDODERMIS

Etymology of ENDODERMIS

The word "endodermis" is derived from two Greek roots: "endo" meaning "inside" and "dermis" meaning "skin" or "layer".

In biological terms, the endodermis refers to the innermost layer of cells that surrounds the central cylinder (stele) of roots and stems in plants. It is involved in regulating the movement of water and nutrients from the roots to the rest of the plant. The name "endodermis" was given to this layer because it forms a protective barrier and separates the internal tissues from the external environment, much like the function of skin in animals.
