MARGINAL PLATES Meaning and
Definition
-
Marginal plates refer to the specialized growths or structures found on the margins or edges of certain organisms, particularly those in the plant and animal kingdoms. These plates can be found in various forms depending on the organism in question.
In the botanical context, marginal plates are typically observed in certain types of leaves. These plates are thin, flat extensions or ridges that are positioned along the leaf edges. They may have distinct shapes and textures, such as serrated, toothed, lobed, or scalloped forms. Marginal plates in some plants serve protective functions, acting as a deterrent against herbivores or predators. They may also play a role in regulating the exchange of gases or reducing evaporation rates.
In the zoological context, marginal plates are commonly observed in marine invertebrates such as echinoderms, specifically in species like starfish, sea urchins, and sand dollars. These plates are calcified structures arranged along the edges of the animal's arm or body, providing support and protection. Marginal plates in echinoderms are typically rough-textured and interconnected, forming a rigid skeletal structure known as the test, which encloses and protects their internal organs.
Overall, the term "marginal plates" is used to describe the distinctive characteristics and adaptations seen at the periphery of certain organisms, serving various functions depending on the species.

Etymology of MARGINAL PLATES
The word "marginal" is derived from the Late Latin word "marginalis", which means "of or pertaining to a border". It comes from the Latin word "margo", meaning "edge" or "border".
The term "plate" in this context refers to a flat, thin, or extended piece of material. Its etymology can be traced back to the Old French word "plate", which means "small, flat, and thin piece of metal". This word originated from the Latin "plattus", meaning "flat" or "broad".
Therefore, the term "marginal plates" refers to thin, flat pieces located at the border or edge of something. In various domains, such as biology or geology, "marginal plates" specifically refers to the thin, flat structures found at the edges or borders of certain organisms or geological formations.
