COLLAR CELL Meaning and
Definition
-
A collar cell, also known as a choanocyte, is a specialized cell found in sponges, which are multicellular aquatic organisms of the phylum Porifera. These cells are named for their characteristic collar-like structure, formed by a cylindrical or conical collar surrounding a flagellum.
Collar cells play a vital role in several essential functions within the sponge body. They are primarily responsible for filtering and capturing food particles from the surrounding water. By utilizing their flagella, collar cells create water currents within the sponge, guiding the flow through small openings called ostia. As water passes through the sponge, collar cells continuously beat their flagella, creating a force that propels water through the collar, thereby trapping tiny food particles in the sticky mucus secreted by the collar.
In addition to their role in nutrition, collar cells are also involved in gas exchange and waste removal. They exchange respiratory gases, such as oxygen and carbon dioxide, with the external environment, while simultaneously aiding in the expulsion of metabolic waste products from the sponge. Collar cells are often found lining the internal cavities of sponges, contributing to the overall efficient functioning of the organism.
The intricate structure and specialized functions of collar cells make them a vital part of the sponge's feeding and respiratory systems, enabling these unique organisms to survive and thrive in various aquatic environments.

Etymology of COLLAR CELL
The word "collar cell" is made up of two parts: "collar" and "cell". The term "collar" in this context refers to the appearance of a ring-like structure surrounding the base of the flagellum, which is characteristic of certain types of cells. It is called a collar because of its shape, resembling a collar worn around the neck.The word "cell" has its roots in the Latin word "cella", which means small room or chamber. In biology, a cell refers to the basic structural and functional unit of all living organisms.The term "collar cell" is commonly used in the field of biology to describe a type of specialized cell found in sponges (phylum Porifera). These cells, also known as choanocytes, have a collar-like structure that surrounds a flagellum. They play a crucial role in water filtration and food capture in sponges.
