You must have seen fungus on your stale food. Haven’t you? It feels so disgusting and yucky! Isn’t it? But, do you know that fungi have a kingdom of their own? We are going to learn about them in this chapter. We will look at the characteristics and classifications of fungi.

Characteristics of Fungi
Now, we will look at the various characteristics of fungi kingdom.
Thallus Organisation
The plant body of true fungi is a thallus. It may be non-mycelial or mycelial. The non-mycelial forms are unicellular. However, they may form a pseudomycelium by budding. In mycelial forms, the plant body is made up of thread-like structures called hyphae(sing. hypha).
Cell Organisation
The cell wall of fungi is mainly made up of chitin and cellulose. Chitin is a polymer of N-acetyl glucosamine. On the other hand, the cellulose is nothing but a polymer of d-glucose. Besides, the cell wall may be made up of cellulose-glycogen, cellulose-chitin or polygalactosamine-galactan.
Nutrition
The fungi are achlorophyllous organisms. Hence, they cannot prepare their food. They live as heterotrophs i.e., as parasites and saprophytes. Some forms live symbiotically with other green forms.
Parasites: They usually obtain their food from a living host. A parasite could be facultative or obligate. The obligate parasites survive and settle on a living host throughout their life. The facultative parasites are saprophytes that have turned parasitic.
Saprophytes: These organisms procure their nutrition from dead and decaying organic matter. The saprophytes are either obligate or facultative. An obligate saprophyte remains saprophytic during its entire lifetime. While a facultative saprophyte is nothing but a parasite that has secondarily become saprophytic.
Symbionts: Some fungi develop in symbiotic association with the green or blue-green algae. These constitute the lichen. Here the algal component is photosynthetic. While the fungal component plays the reproductive part.
