ACHENE Meaning and
Definition
-
An achene is a type of dry, indehiscent fruit that is typically single-seeded and does not split open to release its seed. It is derived from a simple ovary and is surrounded by a thin, dry wall called the pericarp. The pericarp may consist of three layers, namely the exocarp, mesocarp, and endocarp. Achene fruits are commonly found in plants belonging to the Apiaceae, Asteraceae, and Rosaceae families, among others.
Typically small and lightweight, achene fruits often exhibit various shapes, ranging from oval to cylindrical or elongated forms. They also differ in texture, with some being smooth and others exhibiting distinct patterns or structures, such as wings or spines. The development and structure of an achene fruit are advantageous for dispersal mechanisms, allowing it to be easily carried by wind, water, or animals.
Achene fruits are characterized by their ability to release their seed only when the pericarp disintegrates or decays. This mechanism ensures the protection and preservation of the seed until favorable conditions for germination are present. They play a vital role in plant reproduction and dispersal, as the seeds are capable of growing into new plants under suitable environmental conditions. The term "achene" is rooted in Greek, meaning "small" or "little." Within the field of botany, understanding the nature and characteristics of achene fruits is crucial for the classification, identification, and study of plant species and their reproductive strategies.

Etymology of ACHENE
The word "achene" comes from the Latin word "achenium", which was originally derived from the Greek word "achenion". In Ancient Greek, "achenion" referred to a small container or receptacle. The Latin "achenium" specifically referred to a small, dry, one-seeded fruit that does not split open when ripe, characteristic of plants in the sunflower family (Asteraceae). Over time, the term "achene" came to be used as a more general botanical term for such fruits, regardless of their plant family.
