Mushrooms are neither plants nor animals. They are part of the Fungi kingdom, which includes yeasts, moulds, smuts, and rusts. Fungi were once included in the same kingdom as plants because they were sessile and resembled each other in some ways. However, we now know that fungi are more closely related to animals than plants. Fungi reproduce and spread through spores, which is more similar to how plants reproduce than animals. They also lack chlorophyll and have to take nutrients from other materials.

What You'll Learn
Mushrooms are fungi, which are not animals
Mushrooms are a member of the fungi kingdom, which is distinct from the animal kingdom. While mushrooms may resemble plants in some ways, they are not plants either. In fact, animals are more closely related to fungi than they are to plants.
The early classification of mushrooms as plants was based on the fact that both are sessile and share some key characteristics. However, fungi lack chloroplasts and chlorophyll, which are unifying features of plants. Unlike plants, fungi digest nutrients from dead or living material. They reproduce through spores, which is more similar to the method of reproduction in plants than in animals. However, the presence of cell walls and differences in food and digestion are enough for fungi to have their own kingdom, separate from that of plants and animals.
Modern classifications of species are based on molecular genetics. Analyses of the sequences of genes in different organisms have revealed that fungi, plants, and animals each make up distinct branches, with fungi more closely related to animals than to plants. This has led to the creation of separate kingdoms for fungi, plants, and animals, with fungi demanding further taxonomic attention.
Fungi include not only mushrooms but also yeasts, molds, smuts, and rusts. They play an important role in human life, being used in the production of bread, wine, beer, and blue cheese. They have also been used to create antibiotics and other drugs, such as penicillin.

Fungi reproduce differently to animals
Mushrooms are a type of fungus, and fungi are not classified as animals. In fact, fungi form their own kingdom, distinct from the animal kingdom. Fungi are more closely related to animals than they are to plants, but their reproductive methods are very different from those of animals.
Fungi reproduce by forming and releasing spores, which can be produced asexually or sexually. Asexual reproduction is the most common method, and it involves the formation of asexual spores, which are genetically identical to the parent fungus. These spores are produced by one parent only, through a process called mitosis, and they allow fungi to expand their distribution and colonize new environments.
During asexual reproduction, budding can occur in most yeasts and some filamentous fungi. In this process, a bud develops on the surface of the yeast cell or hypha, with its cytoplasm continuous with that of the parent cell. The nucleus of the parent cell divides, and one of the resulting nuclei migrates into the bud, which eventually detaches and becomes an independent yeast cell.
Fungi can also reproduce sexually, and this often occurs in response to adverse environmental conditions. Sexual reproduction introduces genetic variation into a population of fungi. It involves the fusion of two nuclei from two compatible mating types, which can result in the formation of spores.
In contrast, animal reproduction typically involves the formation of specialized reproductive cells called gametes, which combine during fertilization to form a zygote, which develops into a new individual. Animals also have distinct male and female sexes, whereas fungi have mating types that are not always clearly male or female.

Fungi are more closely related to animals than plants
Mushrooms are a type of fungus, and while they were once included in the same kingdom as plants due to their similarities in appearance and life history, they are now known to be more closely related to animals. In fact, humans are more closely related to mushrooms than mushrooms are to plants—meaning that your DNA is more similar to that of a mushroom than a mushroom's is to a tree's.
This classification is based on molecular genetics, which allows scientists to examine the sequences of genes in a set of organisms and infer the structure of the "family tree" that connects them. When this is done for fungi, plants, and animals, three distinct branches emerge, with the branch containing fungi being closer to the branch containing animals than the one with plants.
The distinction between fungi and plants can also be observed in their methods of reproduction and digestion. Fungi reproduce and spread through spores, which is more similar to the method used by plants than animals. However, fungi chemically digest their food, which sets them apart from plants, which photosynthesize.
While the last common ancestor of plants, fungi, and animals existed before the common ancestor of fungi and animals, the split between fungi and animals occurred more recently than the split between plants and animals. In 1998, scientists discovered that fungi split from animals about 1.538 billion years ago, whereas plants split from animals about 9 million years earlier. This provides further evidence that fungi are more closely related to animals than to plants.

Fungi are not immobile, unlike mushrooms
Mushrooms are a type of fungus, and while they may appear immobile, fungi are not. Fungi were once included in the same kingdom as plants because they resembled each other in some key ways and were distinct from animals. However, fungi are now recognized as a separate kingdom due to their distinct characteristics and evolutionary history. Fungi cells differ significantly from plant cells, and their metabolisms work differently.
Fungi are more closely related to animals than they are to plants. They can produce a variety of proteins that are also found in animals, such as chitin, which is present in both insect exoskeletons and the walls of mushroom cells. Additionally, fungi reproduce and spread through spores, which is more similar to plant reproduction than animal reproduction.
Fungi, including mushrooms, lack chlorophyll, the pigment that gives plants their green colour and allows them to harness energy from sunlight. Instead, they obtain their energy through other means. Only lichens, a type of fungus that encapsulates photosynthesizing organisms like green algae, can harness energy from the sun.
While mushrooms may appear immobile, fungi can exhibit movement through the growth and expansion of their hyphae, which are thread-like structures that make up the vegetative body of the fungus. This growth can be rapid and occur in various directions, allowing fungi to explore new sources of nutrients and spread over a wide area. Therefore, while mushrooms themselves may not move, the fungi that produce them are capable of movement and expansion.
In summary, while mushrooms may appear immobile and similar to plants, they belong to the distinct kingdom of Fungi. Fungi are dynamic organisms that exhibit movement through the growth of their hyphae and are more closely related to animals in terms of evolutionary history and certain biological characteristics.

Fungi have their own kingdom
Mushrooms are a type of fungus, and fungi form their own kingdom, distinct from the plant and animal kingdoms. Fungi used to be classified as part of the plant kingdom due to similarities in lifestyle and morphology. However, fungi are not plants, and in fact, animals are more closely related to fungi than they are to plants.
Fungi reproduce and spread through spores, which is more similar to plant reproduction than animal reproduction. However, the presence of cell walls and the absence of chloroplasts, as well as differences in food and digestion, are enough for fungi to have their own kingdom.
Fungi, like animals, are heterotrophs, meaning they acquire their food by absorbing dissolved organic molecules by secreting digestive enzymes into their environment. They do not photosynthesize. Fungi are the principal decomposers in ecological systems.
There is a vast number of fungus species, with estimates ranging from 2.2 to 3.8 million species. However, the global biodiversity of the fungus kingdom is not fully understood, and new species are being discovered every year. The potential of the fungi kingdom is immense and largely untapped, with ongoing research into how we can utilise this complex and mysterious kingdom.
