ORGANELLE Meaning and
Definition
-
Organelle refers to a specialized, distinct structure that is found within the cells of organisms. These structures are considered to be the functional units of cells and have specific roles in carrying out various cellular activities. Organelles are typically enclosed within a membrane and are present in both eukaryotic and prokaryotic cells.
In eukaryotic cells, which make up plants, animals, fungi, and protists, organelles are enclosed within a double-layered membrane called the nuclear envelope. Some of the most well-known organelles in eukaryotic cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and plastids (like chloroplasts in plants). Each organelle performs specific functions that contribute to the overall survival and functioning of the cell. For instance, the nucleus contains the genetic material and coordinates the cell's activities, while mitochondria generate energy for the cell through cellular respiration.
In prokaryotic cells, which include bacteria and archaea, organelles are simpler and lack a membrane. These organelles, often referred to as inclusion bodies, serve functions like energy storage, waste management, or maintaining cell shape.
Overall, organelles are crucial components of cells that carry out specialized functions needed for survival, growth, and reproduction. The presence and diversity of organelles highlight the complexity and efficiency of cellular organization and function.

Etymology of ORGANELLE
The word "organelle" is derived from the combination of two Greek words: "organelle" (ὀργανέλλα) and "organon" (ὄργανον).
The word "organon" means "instrument" or "tool" in Greek. It has been historically used to refer to various types of instruments or tools.
The suffix "-elle" is a diminutive form in Greek, typically used to indicate something small or subordinate.
Putting these two components together, "organelle" can be translated as "little organ" or "subordinate instrument/tool".
The term "organelle" was first coined in the early 20th century to describe specialized structures within cells that perform specific functions. The concept of organelles came about as scientists began to discover and study the various components and structures present within cells.
