Mushrooms are a lot like plants, but they are not plants. They are a type of fungus, constituting their own kingdom, separate from plants and animals. Fungi have their own unique set of health benefits that cannot be found in the traditional plant and animal food groups. Mushrooms are the fruiting body of some types of fungus, which grows underground or in rotting logs to distribute spores, similar to how plants spread seeds.

| What is a mushroom? | The fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or another food source. |
| How does it grow? | The fungus's mycelium grows underground, similar to the roots of a plant. The mushroom fruits above the ground, and the spores within the gills are like seeds. |
| How does it differ from plants? | Mushrooms are not plants because they lack chlorophyll for food production. They get their energy and nutrients by digesting other things. |
| How does it differ from animals? | Mushrooms are not animals because they do not eat and digest. Instead, the mycelium grows into and around the food source, secreting enzymes for external digestion. |

What You'll Learn
Mushrooms are a type of fungus
Mushrooms are the fruiting bodies of some types of fungus. The fungus's mycelium grows underground, similar to the roots of a plant, and the mushroom fruits above ground. Instead of seeds, mushrooms produce spores, which are like fine smoke and help the fungus spread across the ground or its occupant surface. Each mushroom has billions of spores. Mushrooms don't have chlorophyll and cannot produce their own food through photosynthesis like plants can. Instead, they get their energy and nutrients from digesting other things, like animals do.
Fungi have cell walls made rigid with chitin, rather than cellulose as in plants. Their cells usually have half of a full set of DNA, while in plants and animals, each cell has a full set, and only eggs and sperm have half sets. Fungi also lack chloroplasts, which are necessary for photosynthesis. These differences in basic cell function mean that fungi are distinct from plants and animals.
Fungi play an important role in nature and have many uses. Mycorrhizal fungi, for example, are important to many plants and are used by horticulturalists to encourage plant growth. Fungi are also used to create antibiotics and other drugs. In addition, fungi are present in many foods we eat, such as bread, beer, wine, and blue cheese.

Fungi are not plants
Mushrooms are a type of fungus, and fungi are not plants. While mushrooms may grow in a similar way to plants, they are fundamentally different. Fungi are a separate branch of life from plants and animals, constituting their own kingdom of life. Fungi include yeasts, moulds, smuts, and rusts, in addition to the more familiar mushroom-forming species.
Fungi have a unique method of feeding that distinguishes them from plants and animals. Unlike plants, fungi do not contain chlorophyll and cannot photosynthesize. Instead, they obtain their energy and nutrients by secreting digestive enzymes into their environment and absorbing nutrients from it. This process is similar to how animals feed, but fungi do not ingest their food like animals do. Fungi live inside their food and absorb nutrients from it.
Another key difference between fungi and plants is the composition of their cell walls. Plant cells are made rigid with cellulose, while fungi cells contain chitin. Additionally, plant cells typically store food as starches, whereas fungi store food as glycogen, similar to animals.
The classification of organisms is based on the function and structure of their cells, as well as their genetic lineage. While fungi may exhibit some plant-like and animal-like behaviours, their cellular structure and metabolism are distinct from those of plants. This classification is important because it affects how we understand, support, and engage with different organisms.
In summary, fungi are not plants. They have their own unique characteristics and play a crucial role in ecosystems and the transformation of organic compounds.

Fungi are closely related to animals
Mushrooms are the fruiting bodies of some types of fungus. They are neither plants nor animals. Fungi constitute their own kingdom, which includes the familiar mushroom-forming species, as well as yeasts, moulds, smuts, and rusts. Fungi and mushrooms are often associated with plants because they grow in similar ways. However, fungi do not have chloroplasts that photosynthesize; instead, they obtain their energy and nutrients by digesting other things, like animals do.
Fungi are, in fact, more closely related to animals than to plants. They form a clade called opisthokonta, which is named after a single, posterior flagellum present in their last common ancestor. This flagellum propels primitive fungal spores and animal sperm. Phylogenetic analysis of various proteins has also revealed that fungi and animals share a more recent common ancestor. This means that humans are more closely related to mushrooms than to tulips, for example.
Fungi and animals have been shown to be sister groups, while plants constitute an independent evolutionary lineage. The last common ancestor of plants, fungi, and animals was earlier than the last common ancestor of fungi and animals. This means that fungi and animals are equally related to plants. The plant/animal/fungi split occurred in single-cell days, with fungi splitting from animals about 1.538 billion years ago and plants splitting from animals about 1.547 billion years ago. This indicates that fungi and animals share a more recent evolutionary history.
Additionally, there are several fundamental differences between fungi and plants at the cellular level. Fungi have cell walls made rigid with chitin, while plants have cell walls made of cellulose. The cells of fungi usually have half of a full set of DNA, whereas in plants and animals, each cell has a full set, and only eggs and sperm have half sets. These differences provide further evidence that fungi are distinct from plants and more closely related to animals.

Mushrooms are the fruiting body of fungi
Mushrooms are a lot like plants, but they are not plants. They are also not animals. They constitute their own kingdom: the Fungi. Fungi include the familiar mushroom-forming species, as well as yeasts, moulds, smuts, and rusts.
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 are the fleshy, spore-bearing fruiting body of fungi. They are formed from hyphae, the tiny threads that make up the bulk of most fungi. A network of hyphae, known as a mycelium, extends in all directions through the soil. The gills on the underside of the mushroom cap produce microscopic spores, which are like mushroom versions of seeds. These spores help the fungus spread across the ground or its occupant surface.
The delineation between edible and poisonous fungi is not clear-cut, so a "mushroom" may be edible, poisonous, or unpalatable. Many mushrooms are famously delicious and nutritious, while others are notoriously deadly. Therefore, it is important not to eat any mushroom unless you are certain it is safe to eat.

Mushrooms produce spores
Mushrooms are the fruiting bodies of fungi. They are neither plants nor animals but constitute their own kingdom: the Fungi kingdom. Fungi, including mushrooms, produce spores to spread and find new food sources, create new strains, and ensure the survival of their species.
Spores are microscopic, single-celled reproductive structures that are almost as fine as smoke. They are often compared to plant seeds, and their name comes from the Greek word "sporā," which means "seed." However, spores are not the same as seeds. While plant seeds contain all the genetic material needed to grow a new plant, spores are non-motile single cells with a solid cell wall that do not contain much food. Therefore, spores must land in a spot with a suitable food source and specific environmental conditions, such as the correct temperature range and humidity levels, to germinate.
Mushrooms use convectively created airflows to disperse their spores. The distance spores disperse is influenced by factors such as the shape asymmetry and temperature differentials along the pileus, rather than the pileus diameter or the rate of spore production. The presence of nearby boundaries for the upward-flowing part of the current to climb can enhance spore dispersal. Mushrooms produce billions of spores daily, and a single mushroom can produce billions of spores in a day. However, most spores will never become new fungi due to various obstacles, such as the lack of a suitable food source and environmental conditions.
