Agar is a city located in India. It is characterized by its geographical location within the country's regional landscape.
The term Agar is also associated with agar-agar, which is a jelly-like substance composed of polysaccharides. These substances are derived from the cell walls of specific species of red algae, primarily those from the Gracilaria genus and the Gelidiaceae family, also known as tengusa. These types of algae are classified as agarophytes.
