Mushrooms are fleshy, spore-bearing fruiting bodies of fungi, typically produced above ground on soil or another food source. They are neither plants nor animals, constituting their own kingdom: the Fungi. They include the familiar mushroom-forming species, as well as yeasts, moulds, smuts, and rusts. Fungi, including mushrooms, play a vital role in nature and to humans. They are responsible for breaking down dead materials, keeping us from drowning in a sea of leaf litter and fallen branches. They also have many uses, from making bread rise to creating antibiotics and other drugs.

What You'll Learn
Mushrooms are part of the Fungi kingdom, not plants
Mushrooms are part of the Fungi kingdom, which is separate from the plant kingdom. Fungi were long classified as plants, but in the 20th century, scientists began to recognise that they have unique traits that set them apart from plants.
Fungi are more closely related to animals than plants. They lack chlorophyll, which is used by plants for food production, and they don't make their own food through photosynthesis. Instead, they secrete digestive enzymes and absorb nutrients from their surroundings. This is a key ecological difference that separates fungi from plants.
Fungi also have unique cellular components that distinguish them from plants. For example, fungal cell walls contain chitin, not cellulose. They also reproduce by spreading tiny spores, which are like seeds, by the wind.
The part of the mushroom that is visible and edible is just a small part of the organism. Most of a mushroom's body is long, web-like strands called mycelium, which grow into the food source and absorb nutrients.
Fungi have their own set of health benefits that are unique from the traditional plant and animal food groups. They have been used for the production of antibiotics and enzymes, and in biological pesticides.

Fungi are more closely related to animals than plants
Although mushrooms are commonly thought of as vegetables due to their culinary usage, they are not a part of the plant kingdom. Mushrooms are the fleshy, spore-bearing fruiting bodies of fungi. The mycelium of the fungus grows underground, similar to the roots of a plant, and the spores within the gills are like seeds. However, mushrooms do not have chlorophyll for food production, and they do not make energy through photosynthesis like plants. Instead, they obtain energy by breaking down and eating dead organic matter, like fallen trees and leaves. This process of external digestion is more similar to how animals obtain energy.
Historically, fungi were classified as plants based on observations of their immobility and rigid cell walls. However, this classification has been updated due to advancements in molecular biology. Computational phylogenetics comparing eukaryotes revealed that fungi are more closely related to animals than to plants. In 1998, scientists discovered that fungi and animals shared a more recent common ancestor than plants and fungi. This common ancestor possessed a single, posterior flagellum, which is still present in primitive fungal spores and animal sperm today.
Fungi and animals form a clade called opisthokonta, further supporting their closer evolutionary relationship. While it may seem counterintuitive to think of mushrooms as more closely related to animals than plants, this classification is based on genetic and evolutionary evidence. The distinction between fungi and plants is important because it affects how we understand and support different organisms in scientific research, financial investments, and cultural appreciation.

Mushrooms lack chlorophyll and have to take nutrients from other materials
Mushrooms are a lot like plants, but they are not plants. Mushrooms are part of the Fungi kingdom, which also includes yeasts, moulds, smuts, and rusts. Fungi, including mushrooms, lack chlorophyll and have to take nutrients from other materials.
Plants make energy from sunlight through a process called photosynthesis. Chlorophyll is a vital component of photosynthesis, and it is this process that distinguishes plants from mushrooms and other fungi. Mushrooms, on the other hand, get their energy from other organisms, much like animals do. They break down and eat dead organic material, such as fallen trees, leaves, and dead animals. This process is called detritivory, and it is how fungi return nutrients to the soil for new plants to use.
The mushroom is just one part of the fungus, which is mostly underground. The visible mushroom is the fruiting body of the fungus, which produces spores to reproduce. The rest of the fungus is a network of long, web-like strands called mycelium, which grow into the food source. The mycelium secretes digestive enzymes to break down the dead tissue, and then absorbs the nutrients.
Mushrooms were long classified as plants, but it was eventually determined that they are more closely related to animals. They are neither plants nor animals, but constitute their own kingdom.

Mushrooms produce spores, not seeds
Mushrooms are part of the fungi kingdom, and while they were once classified as plants, they are now known to be more closely related to animals. Fungi, including mushrooms, produce spores, not seeds. These spores are produced on the gills of mushrooms and are released in a fine rain of powder. They are extremely small, with tens of thousands of spores able to fit on a pinhead.
The spores are spread by wind and if they land in a moist place with enough food and water, they will germinate and grow into a new mushroom. This process is how mushrooms reproduce. The spores are like seeds in that they give rise to new generations of fungi, but they are distinct in that they do not contain the fungus' genetic material. Instead, spores are spread to new locations where they may develop undesirable parental genetics.
The part of the mushroom that is visible and edible is just a small part of the organism. Most of a mushroom's body is long, web-like strands called mycelium, which grow underground and into the food source. The mycelium secretes digestive enzymes that break down the food, and then the nutrients are absorbed. This process is how fungi get their energy, as they do not use photosynthesis like plants do.
Mushrooms and other fungi are extremely important ecologically as they break down dead organic material and return nutrients to the soil. They also have unique health benefits that cannot be found in plants or animals.

Mushrooms grow from mycelium, not roots
Mushrooms are the fruiting bodies of fungi. They are not plants because they do not have chlorophyll for food production, and they are not animals because they do not eat and digest. Instead, they secrete enzymes for external digestion and then absorb the already-digested nutrients.
Mushrooms grow from mycelium, which is a network of thin filaments called hyphae. Each hypha is surrounded by a robust fungal cell wall that collects food, water, and nutrients to nourish the fungus. The mycelium also provides the mushroom with support and anchorage.
The mycelium grows underground, similar to the roots of a plant, and the mushroom fruits above ground. However, unlike plants, mycelium does not engage in cellular respiration or photosynthesis. Instead, it excretes enzymes that break down organic matter into usable nutrients, which it then absorbs.
The mycelial network is like the roots, trunk, branches, and leaves of a plant, while the mushrooms are the fruit. This network is hidden and remains unseen, as most of it is intertwined with the substrate it is growing on.
Supplements made from mycelium may contain varying levels of active compounds, and mycelium-based meat is a nutritious alternative to animal-based meat, with all the essential amino acids and significantly more benefits.
