Mushrooms are neither plants nor animals; they are fungi. Fungi have historically been grouped with plants, but this classification is no longer considered accurate. Fungi are more closely related to animals than plants, and they have their own unique characteristics that distinguish them from both plants and animals. For example, they do not photosynthesize like plants, nor do they ingest their food like animals. Instead, they live inside their food and secrete enzymes to dissolve nutrients before absorbing them. This unique ability makes fungi essential to decomposition and the beginning of a fundamental natural process that enables life.

What You'll Learn
Mushrooms are a type of fungus
The earliest attempts at classifying fungi were made by early taxonomists who observed mushrooms and determined that they were immobile and had rigid cell walls. These characteristics were sufficient for early scientists to conclude that fungi were not animals and to group them with plants. However, fungi are now understood to be more closely related to animals than to plants, sharing a common ancestor in the form of an opisthokont, a cell with a posterior flagellum, similar to human spermatozoids.
Fungi play a crucial role in nature and for humans. They are responsible for breaking down dead materials, keeping us from being overwhelmed by leaf litter and fallen branches. They also form mutually beneficial relationships with plants, helping them absorb water and minerals in exchange for nutrients. In addition, they are essential for bread, chocolate, cheese, soy sauce, beer, and wine production.
Fungi, including mushrooms, have been used in fashion and are known for their medicinal properties, with some strains of penicillin being isolated from fungi. Despite their importance, fungi are often overlooked in environmental, biodiversity, and conservation laws and policies. Efforts are being made to extend legal protections to fungi, recognizing their vital role in ecosystems.

Fungi are not plants
Fungi, including mushrooms, are not plants. They are their own kingdom. While fungi were historically classified as plants, this was due to the limitations of early taxonomic tools and methodologies. Today, we know that fungi are more closely related to animals than plants.
Fungi do not photosynthesize like plants. Instead, they secrete enzymes to dissolve the nutrients in their food and then absorb them. This is because, unlike plants, fungi lack chlorophyll and must take nutrients from other materials.
Fungi also reproduce differently from plants. Instead of seeds, mushrooms—the fruiting structures of fungi—produce spores, which are almost as fine as smoke. When spores land in a suitable place, they germinate and develop into a new fungus.
Fungi also form mutually beneficial relationships with the roots of plants, helping them to absorb water and minerals in exchange for nutrients. Many plants, including trees and orchids, cannot live without these fungal partners.

Fungi are not animals
Fungi, which include mushrooms, are not animals. They are their own kingdom, distinct from plants and animals. Fungi do not photosynthesize like plants, nor do they ingest food like animals. Instead, they live inside their food and secrete enzymes to dissolve nutrients, which they then absorb.
Fungi also lack chlorophyll and have to take nutrients from other materials. They produce spores, which are almost as fine as smoke, instead of seeds. When spores land in a suitable place, they germinate and develop into a new fungus.
Fungi include yeasts, molds, smuts, and rusts, in addition to the familiar mushroom-forming species. They play a vital role in nature and for humans. For example, they are responsible for breaking down dead materials, keeping us from being overwhelmed by leaf litter and fallen branches. They also have important applications in food and beverage production, such as in bread, chocolate, cheese, soy sauce, beer, and wine.
In the past, fungi were classified as plants, based on early observations of mushrooms, which suggested that fungi were immobile and had rigid cell walls. However, this classification has shifted with advances in molecular tools and a better understanding of evolution. Now, it is known that fungi are more closely related to animals than to plants, sharing a common ancestor in the form of an opisthokont, a cell with a posterior flagellum.

Fungi are closely related to animals
Mushrooms are neither plants nor animals. They are part of their own kingdom: the Fungi. This kingdom includes yeasts, moulds, smuts, and rusts, in addition to the mushroom-forming species. Fungi, unlike plants, lack chlorophyll and must obtain nutrients from other materials. They are also distinct from animals.
Fungi and animals are more closely related to each other than either is to plants. Phylogenetic analyses of 25 proteins revealed four insertions/deletions shared by animals and fungi but not plants, protists, or bacteria. These include a 12-amino acid insertion in translation elongation factor 1 alpha and three small gaps in enolase. This evidence suggests that animals and fungi are sister groups, while plants constitute an independent evolutionary lineage.
Further support for the close relationship between animals and fungi comes from the examination of the 90 kD heat shock family of protein sequences. Bootstrap analyses of these sequences show no support for either an animal-plant or fungal-plant clade, indicating that animals and fungi are more closely related.
The last common ancestor of plants, fungi, and animals lived earlier than the last common ancestor of fungi and animals. This means that fungi and animals are equally related to plants, but more closely related to each other. In 1998, scientists estimated that fungi split from animals about 1.538 billion years ago, while plants split from animals about 9 million years earlier. However, more recent research suggests that the divergence between animals and fungi may have occurred much earlier, approximately 1,360 million years ago.
Fungi play important roles in nature and for humans. They are responsible for breaking down dead materials, preventing leaf litter and fallen branches from accumulating. Some fungi form mutually beneficial relationships with plant roots, helping with water and mineral absorption while receiving nutrients in return. Fungi are also used in food production, such as in the fermentation process for bread, wine, and beer, and in the creation of antibiotics and other drugs.

Fungi are distinct in how they feed
Mushrooms are fungi, and fungi are distinct from plants and animals in how they feed. Fungi are heterotrophs, meaning they cannot produce their own food through photosynthesis like plants do. Instead, they acquire their food by absorbing dissolved molecules from their environment. They secrete digestive enzymes that break down organic matter, making it easier to absorb the nutrients. This process of decomposition is essential for recycling nutrients back into the ecosystem.
Fungi feed on dead or decaying organic matter, including dead plants and animals, and are thus known as saprotrophs or saprophytes. They play a crucial role in breaking down leaf litter and other debris, preventing their accumulation. Examples of saprotrophic fungi include shiitake and oyster mushrooms.
Some fungi are parasitic, feeding on living organisms without killing them. These parasitic fungi can cause diseases such as ergot, corn smut, Dutch elm disease, and ringworm. Many plants, including orchids, depend on symbiotic relationships with mycorrhizal fungi to help them acquire water and nutrients from the soil.
Fungi can also be predatory, actively capturing prey such as nematodes using specialized structures like constricting rings or adhesive nets.
The mode of feeding and nutrition defines the role of fungi in their environment. Fungi have evolved to utilize a wide variety of organic substrates for growth, including simple compounds found in their surroundings. This adaptability makes them versatile and integral members of their ecosystems.
