Fungi are eukaryotic organisms that include microorganisms such as yeasts and moulds, as well as mushrooms. Fungi are different from plants, bacteria, and some protists due to the presence of chitin in their cell walls. They are also different in that they do not photosynthesize. Fungi are heterotrophs and acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. They are also one of the most important decomposers of dead plant material, and the recycling of nutrients back into ecosystems. Fungi can be unicellular or multicellular, and mushrooms are multicellular fungi.

What You'll Learn
Mushrooms are the fruiting bodies of fungi
Mushrooms are multicellular fungi that are part of the kingdom Eumycota (true fungi or Eumycetes). Fungi are eukaryotic organisms with cell walls, and, except for yeast, most fungi are multicellular. Yeast is a common name for unicellular fungi.
The fruiting bodies of fungi are important for reproduction. They are also a source of food and have various industrial applications. Fungi are used in the production of antibiotics and enzymes used in detergents and industry. They are also used as biological pesticides to control weeds, plant diseases, and insect pests.
The study of fungi is known as mycology. Mycology is an important field of biology because fungi play crucial ecological and economic roles. Fungi are significant decomposers of dead plant material and recyclers of nutrients in ecosystems. They also help plants absorb more nutrients.

Fungi are mostly multicellular
Fungi are eukaryotic organisms, which means they have a nucleus enclosed by a membrane. They include microorganisms such as yeasts and moulds, as well as the more familiar mushrooms. With the exception of yeast, which is unicellular, fungi are multicellular. Yeast is a common name for a unicellular fungus, and around 1,500 species of fungi are recognised as yeasts.
Mushrooms are the fruiting bodies common to many species of fungi and are used to store and release spores into the environment. They are made from a collection of fungal cells called hyphae, which are woven together to produce a spore-bearing mushroom. Two groups of multicellular fungi contain over 95% of all species, one of which is called 'basidiomycetes', which includes the mushroom-producing fungi.
The evolution of multicellularity has been a major transition in the history of life. Fungi have solved some of the common challenges associated with the evolution of multi-celled organisms, such as apical growth, compartmentalisation, and cell-to-cell communication.

Fungi have chitin in their cell walls
Mushrooms are multicellular fungi. Fungi are eukaryotic organisms that are neither plants, animals, nor prokaryotes. They form a kingdom of their own. Most fungi are multicellular, although some are unicellular, such as yeast. Fungi are different from other living things due to the type of cell wall they have. Unlike plants, bacteria, and some protists, which have cell walls made from cellulose, the cell walls of fungi contain chitin.
Chitin is a polymer of N-acetylglucosamine, a glucose precursor. Fungi are heterotrophs, meaning they either take sugar from their environment or make it via gluconeogenesis. They do not have chloroplasts, so they cannot photosynthesize and produce glucose. Instead, they often derive sugar from the degradation of cellulose.
Chitin provides important structural stability to fungal cell walls. It is more flexible than cellulose and offers better structural support and protection for fungal cells. Chitin is more resistant to degradation by enzymes and other organisms, helping to protect fungal cells from external threats. It also forms tight junctions between cells, maintaining the integrity of fungal cell walls and preventing the entry of harmful substances.
Chitin is a key component of the fungal cell wall, which is located outside the plasma membrane. The cell wall is a skeleton that provides rigidity and defines the cellular structure. It is highly plastic and protects the cell from various stresses, particularly osmotic changes. The cell wall also allows interaction with the external environment, as some of its proteins are adhesins and receptors.
The presence of chitin in fungal cell walls has implications for medicine. As the components of fungal cell walls are not present in humans, they are an excellent target for antifungal therapy. β-glucans and mannans, for example, are useful diagnostic tools for detecting invasive fungal infections.

Yeast is a unicellular fungus
Fungi are eukaryotic organisms with cell walls made from a compound called chitin. They are different from plants, bacteria, and some protists, whose cell walls are made from other compounds like cellulose. Fungi can be multicellular or single-celled organisms, with the latter referred to as yeasts.
Yeasts are a type of unicellular fungus. They are easily distinguishable from other forms of eukaryotic unicellular life due to their unique method of cell division. When yeasts divide, they do so by budding a smaller cell from a larger one, whereas protists divide into two roughly equal cells. This suggests that yeasts may have descended from multicellular ancestors that formed vegetative propagules.
Yeasts are probably one of the earliest domesticated organisms. Archaeologists have found evidence of yeast use in ancient Egypt and Israel, including drawings of 4,000-year-old bakeries and breweries, as well as yeast colonies in vessels believed to have contained alcoholic beverages. Yeasts have been recognized as fungi for a long time, and this classification is due to their evolutionary history and close relationship to other fungi.
The yeast species Saccharomyces cerevisiae, also known as "true yeast," is a common type of yeast that plays a significant role in baking and the production of alcoholic beverages. It converts carbohydrates to carbon dioxide and alcohols through the process of fermentation. Other species of yeasts, such as Candida albicans, are opportunistic pathogens that can cause infections in humans.

Fungi are decomposers of dead plant material
Fungi, including mushrooms, are microorganisms that play a crucial role in the decomposition of dead plant material and the recycling of nutrients back into ecosystems. They are heterotrophs, meaning they rely on other organisms for nutrition. When plants and animals die, they become food sources for decomposers like fungi, bacteria, and earthworms.
Fungi are unique among living things due to the type of cell wall they possess. Their cell walls are composed of chitin, a compound that also occurs in the exoskeletons of insects, spiders, and other arthropods. This chitin provides structural support to the thin cells of the fungus. The vegetative body of a fungus can be either unicellular or multicellular. Most fungi are multicellular, and their cells are long, thread-like, and connected end-to-end, forming filaments called hyphae. These hyphae create a complex network called a mycelium, which has an incredibly high surface area to volume ratio, making fungi well-adapted to absorbing nutrients from their surroundings.
Mushrooms are the fruiting bodies of many species of fungi, used for storing and releasing spores into the environment. They are particularly common in damp areas, where they are most efficient at decomposing. The presence of mushrooms indicates the existence of fungi, which would otherwise be almost invisible. Fungi produce mushrooms to facilitate reproduction, as they release huge numbers of spores.
Fungi are essential decomposers of dead plant material, especially in forest ecosystems. They are the primary decomposers of litter, including fallen trees and branches with high concentrations of lignin. Fungi possess the necessary lignin-modifying enzymes to break down lignin, a chemically complex molecule, and cellulose in dead plants. By releasing enzymes, fungi decompose organic matter and subsequently absorb the nutrients from the decaying material. This process of decomposition returns vital nutrients to the soil, enhancing soil fertility and supporting plant growth.
