No, agar is not a fungi.
Agar is a gelatinous substance derived from red algae, specifically agarophytes belonging to the phylum Rhodophyta. It is extracted from the cell walls of these algae and is composed primarily of the polysaccharide agarose. It is widely used as a solidifying agent in microbiological culture media, as well as in various food and biotechnological applications. Fungi, on the other hand, belong to a separate kingdom and are distinct organisms. Therefore, agar and fungi are completely different biological entities.
