Mushrooms are a lot like plants, but they are not plants. They are fungi, and they constitute their own kingdom. They lack chlorophyll and have to take nutrients from other materials. They are made of cells and need energy to survive, grow and reproduce. They are neither plants nor animals, and they are not complete life forms. Mushrooms are usually thought of as the cap or top of the mushroom, but most of the fungi is actually hidden underground. They produce spores, which are almost as fine as smoke, and these spores help the fungus spread across the ground.

What You'll Learn
Mushrooms are part of the Fungi kingdom
Mushrooms are indeed part of the Fungi kingdom. They are neither plants nor animals, but their own distinct kingdom. Mushrooms and other fungi were once classified as part of the plant kingdom, but modern science has since separated them. Fungi are distinguished from plants by their lack of chlorophyll, their inability to photosynthesise, and their cell walls, which are made of chitin rather than cellulose.
Fungi, including mushrooms, are eukaryotic and heterotrophic, meaning they cannot produce their own food and must gain energy by consuming other organisms. They can obtain nutrients from both living and dead organic matter. Some fungi, known as saprophytes, digest nutrients from dead material such as leaves and fallen trees. Others, called parasites, digest materials from living tissues, such as the trees in which they are often found.
The mushrooms we see are the caps or toadstools of the fungus, which are the spore-bearing fruiting bodies. The fungus itself lives as a mycelium, a network of filaments infusing a patch of soil or wood. When conditions are right, the mycelium develops a mushroom, which emerges from the ground or the tree. Mushrooms produce spores, which are almost as fine as smoke, to help the fungus spread.
Fungi play an important role in the ecosystem, and many trees, orchids, and other plants cannot live without their fungal partners. They are also used by humans to make blue cheese, antibiotics, and other drugs.

Mushrooms are not complete life forms
Mushrooms are the “fleshy, spore-bearing fruiting body of a fungus", typically produced above ground. They are neither plants nor animals, but belong to their own kingdom: the Fungi. Fungi were once considered part of the plant kingdom, but modern science has distinguished them as separate due to several key differences.
Firstly, unlike plants, fungi are heterotrophic, meaning they cannot produce their own food and must gain energy by consuming other organisms. Plants, on the other hand, are autotrophic and can produce their own food through photosynthesis. Fungi also lack chlorophyll, which is essential for photosynthesis, and have cell walls made of chitin, whereas plants have cell walls of cellulose.
Secondly, the life cycle of mushrooms is very different from that of plants. Most of a mushroom's life cycle takes place underground or beneath the bark of dead or living trees. Before developing the mushroom structure, the fungus lives as a mycelium, a mat-like or net-like network of filaments infusing a patch of soil or wood. When conditions are right, the mycelium develops a fruiting structure, a mushroom, which emerges from the ground or the tree. Mushrooms produce spores, which are almost like smoke, instead of seeds. These spores help the fungus spread and eventually develop into a new mycelium.
Therefore, while mushrooms are living organisms, they are not complete life forms in the same way that plants or animals are. They are a unique type of organism that belongs to the kingdom Fungi and exhibits characteristics that are distinct from plants and animals.

Mushrooms are made of cells
Mushrooms are multicellular organisms, meaning they are composed of multiple cells. These cells are organised into a unique structure, with the mushroom's “cap” or “toadstool” being the most visible part. Underneath the cap are the gills, which produce microscopic spores that help the fungus spread. The gills are an important feature of mushroom morphology and can be free or attached to the stalk.
The stalk, or stem, provides support to the cap and can be central or off-centre. Some mushrooms, like puffballs, lack a distinct stalk but may have a supporting base. The combination of the cap, gills, and stalk forms the characteristic mushroom shape that is commonly recognised.
The cells that make up mushrooms have distinct characteristics. Unlike plants, which have cell walls made of cellulose, fungal cells have cell walls composed of chitin. This structural difference is one of the key factors that distinguish fungi from plants.
In summary, mushrooms are indeed made of cells, and their cellular composition is an essential aspect of their identity as fungi. Their cellular structure, along with their heterotrophic nature, sets them apart from other kingdoms of life and highlights their unique characteristics within the biological world.

Mushrooms need energy to survive
Mushrooms are a type of fungus, belonging to the Fungi kingdom. They are neither plants nor animals. Fungi are distinct from plants in that they lack chlorophyll and do not carry out photosynthesis. Instead, they derive their energy from external sources. Mushrooms, like other fungi, feed on nutrients from other materials. Some mushrooms derive their energy from dead organic matter, such as leaves and fallen trees, while others obtain their energy from living tissues, making them parasites.
Mushrooms are heterotrophic, meaning they cannot produce their own food and require an external source of energy to survive. They are composed of cells, which are the basic building blocks of life, and must obtain energy to live, grow, and reproduce. Mushrooms are not considered complete life forms, but rather organs of a larger fungal organism.
The part of the mushroom that is typically visible is the “cap" or "toadstool," which is the fleshy, spore-bearing fruiting body of the fungus. The stalk or stem may be central and support the cap, or it may be off-centre or absent altogether. The gills underneath the cap produce microscopic spores, which help the fungus spread. These spores are almost as fine as smoke and are used to classify and identify mushrooms.
Mushrooms play an important role in the ecosystem. They are responsible for decomposing organic matter and recycling nutrients back into the soil. Some mushrooms, known as mycorrhizal fungi, form mutually beneficial relationships with the roots of plants. They help plants absorb water and minerals, and in return, the plants provide nutrients for the fungi. This symbiotic relationship is essential for the survival of many trees, orchids, and other plants.
Mushrooms also have various uses for humans. They are a food source, with some types being cultivated and sold in grocery stores, while others are poisonous and should be avoided. Additionally, fungi are used in the production of antibiotics and other drugs, as well as in the fermentation process for creating cheese, wine, and beer.

Mushrooms are heterotrophic
Fungi are eukaryotic, meaning their cells have a nucleus, just like animal cells. They are also typically multicellular, with each fungus consisting of masses of thread-like structures called hyphae. These hyphae form a network called a mycelium, which can grow into a large and complex structure. The mycelium is the main body of the fungus, responsible for absorbing nutrients and carrying out other life functions.
Mushrooms, as the reproductive structures of fungi, play a crucial role in the life cycle of these organisms. They produce and release spores, which can be carried by wind or water to new locations. When spores land in a suitable environment, they can germinate and grow into new fungi, continuing the life cycle of these heterotrophic organisms.
While mushrooms are considered alive, they are not complete life forms in the same way that animals are. Instead, they are part of the fungus life cycle, which involves the growth and reproduction of the fungus through structures like hyphae, mycelium, and mushrooms. This cycle ensures the survival and propagation of the fungus across different environments.
In summary, mushrooms are heterotrophic organisms that belong to the kingdom Fungi. They play a vital role in the decomposition of organic matter and the recycling of nutrients in ecosystems. Their unique characteristics, such as heterotrophy and the ability to form complex mycelial networks, make them distinct from plants and other life forms.

Frequently asked questions
Mushrooms are living organisms, belonging to the kingdom Fungi. They are made of cells and require energy to survive.
Mushrooms are heterotrophic, meaning they cannot produce their own food. Instead, they get their nutrients from ingesting small pieces of other living organisms or dead organic matter, such as leaves and fallen trees.
The term "mushroom" usually refers to the cultivated white button mushroom, Agaricus bisporus. "Toadstool" generally refers to a poisonous mushroom. However, the delineation between edible and poisonous fungi is not always clear-cut, and some mushrooms that are typically edible can be poisonous depending on where they are growing.
