Mushrooms are a type of fungus and are considered living organisms, despite being very different from other living things like plants and animals. They are more closely related to humans than plants. Mushrooms get their energy from decomposing plant and animal matter, meaning they absorb energy from dead plants and animals. They can be found in dark, damp places like caves or under logs, but also in sunny spots like lawns or the sides of trees. When fungi reproduce, mushrooms are formed, and they release spores that are carried to a place where they will germinate.

What You'll Learn
Mushrooms are a type of fungus
Mushrooms are more closely related to humans than they are to plants. This is because we share a more recent common ancestor with all fungi than we do with plants. This means that mushrooms are more closely related to us than they are to a tulip, for example.
Mushrooms get their energy from decomposing plant and animal matter. They absorb energy from dead plants and animals, which is why they can be found in dark, damp places like under logs or inside caves. However, they can also be found in sunny spots, like on lawns or the sides of trees.
The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus. The term "mushroom" is used to describe the fleshy fruiting bodies of some Ascomycota. These bodies produce microscopic spores, called basidiospores, on their gills. The gills are located on the underside of the cap, or pileus, of the mushroom. These spores help the fungus spread across the ground or its occupant surface.
Mushrooms are neither plants nor animals, but they do play a vital role in nature and for humans. They are saprophytes, which means they break down dead materials and keep us from drowning in a sea of leaf litter and fallen branches and sticks.

They are living organisms
Mushrooms are indeed living organisms. They are a type of fungus, which is a member of the Fungi Kingdom of life. Fungi are distinct from other living things like plants and animals. Unlike plants, mushrooms do not rely on sunlight for energy. Instead, they obtain their energy by breaking down dead organic matter, such as leaves, plants, and even living organisms in some cases. This process of decomposition is essential for creating soil, which is necessary for the survival of many living organisms, including trees.
Mushrooms are versatile and can be found in various environments, including dark, damp places like under logs or in caves, as well as sunnier spots like lawns or tree sides. They are typically characterised by their "'cap' or top, which is bell-shaped and sits atop the 'stalk' or 'stem'. However, most of the fungi are actually hidden underground, forming a vast network called a mycelium. This network is made up of filaments called hyphae, which connect to the stem of the mushroom.
The term "mushroom" is typically used to describe the fleshy, spore-bearing fruiting bodies of certain fungi. These fruiting bodies produce microscopic spores, which help the fungus spread across the ground or its occupant surface. Mushrooms can vary in shape and size, and some even develop a poison that can be dangerous to humans. However, many species of mushrooms are edible and provide essential nutrients to humans and other organisms.
Fungi, including mushrooms, have a unique relationship with plants and other organisms. They can form saprophytic, parasitic, commensal, or mutualistic relationships. In a saprophytic relationship, mushrooms benefit by digesting the tissues of dead plants and trees, creating a beneficial cycle that breaks down dead plant material to create soil. Parasitic relationships occur when a fungus breaks down living tissue, causing illness in the host. Commensal relationships are symbiotic, with the fungus benefiting without any apparent change in the other partner. Mutualistic relationships, such as lichens, benefit both partners, with the fungus receiving food from an algae living as one organism.
Overall, mushrooms are fascinating living organisms that play an essential role in the natural world, providing nourishment and contributing to the creation of soil. They are closely related to humans and have unique reproductive and nutritional processes that set them apart from other living things.

They get energy from decomposing matter
Mushrooms are part of the Fungi Kingdom of life and are living organisms. However, they are very different from other living things like plants and animals. Unlike plants, mushrooms do not rely on the sun to grow and can be found in dark, damp places like under logs or inside caves.
Mushrooms get their energy from decomposing plant and animal matter. They absorb energy from dead plants and animals. This is made possible by the secretion of enzymes that break down complex organic compounds like carbohydrates and proteins into simpler components, which releases energy.
The process of decomposition is vital for the recycling of nutrients into the larger community. Without the symbiotic activity of fungi and bacteria, essential inorganic nutrients from dead animals and plants would be unavailable for use by other organisms, including humans.
Fungi, including mushrooms, play a critical role in the ecosystem by breaking down dead or decaying organic material, such as fallen leaves or dung. This decomposition process allows them to absorb energy and nutrients for their growth and survival.
The mushrooms themselves are the fruiting bodies of fungi, and they produce spores that can germinate and form thread-like structures called mycelia. These mycelia are the ones that absorb energy from the decomposing matter, providing energy for the mushrooms to grow and reproduce.

They have different shapes and sizes
Mushrooms are living organisms and are part of the Fungi Kingdom. They are very different from other living things like plants and animals. Unlike plants, mushrooms do not need sunlight to grow and can be found in dark, damp places like caves or under logs. They can also be found in sunny spots like lawns or the sides of trees.
Mushrooms come in various shapes and sizes, with the cap, or pileus, being the most distinguishable feature. The cap holds the gills or pores of the mushroom and can be smooth or covered with scales or teeth. The shape of the cap can vary from spherical to convex, egg-shaped, bullet-shaped, cone-shaped, or bell-shaped, among others. Some mushrooms, like lion's mane, have "teeth" or shaggy hair-like structures instead of a spherical dome cap.
The size of the mushroom cap can also vary. For example, button mushrooms are typically the smallest, while flat mushrooms, also known as field mushrooms, are larger and ideal for barbecuing or stuffing. Enoki mushrooms are known for their long stems and tiny caps, while oyster mushrooms have long, thick edible stems and smallish caps.
The colour of mushrooms can also vary, from the typical white mushrooms to bright orange saffron milk caps found in Australia. Some mushrooms, like the turkey tail, develop rings of different shades of brown and white as they mature, resembling a turkey's tail.
The unique shapes and sizes of mushroom caps not only protect the delicate gills, pores, and spore-producing structures but also play a crucial role in attracting agents of spore dispersal, aiding in the reproductive success of the fungi.

They are closely related to humans
Mushrooms are indeed living organisms, but they are quite different from other living things like plants and animals. They are part of the Fungi Kingdom and get their energy from decomposing plant and animal matter, meaning they can be found in dark, damp places like caves or under logs, as well as in sunny spots.
Mushrooms and Humans: Close Cousins
It may come as a surprise, but mushrooms are more closely related to humans than to plants. This is because mushrooms and humans share a more recent common ancestor than either does with the lineage leading to plants. In fact, humans share about a quarter to nearly half of their DNA with mushrooms, or fungi more broadly. This is due to the fact that mushrooms and humans evolved from ancestors engaged in multicellularity over a billion years ago. While mushrooms branched off on their evolutionary path, they still retain genetic DNA remnants from our shared origins.
This shared ancestry has led to some interesting similarities between mushrooms and humans. For example, both mushrooms and humans store carbohydrate energy as glycogen, while plants store energy as starch. In addition, both fungi and insects use the polysaccharide chitin to build cell walls, whereas plants use cellulose. Another fascinating parallel is that mushrooms, like humans, produce vitamin D when exposed to sunlight.
Beyond genetics, mushrooms and humans also share some intriguing characteristics. For instance, both have developed powerful medicinal properties. Certain varieties of mushrooms, such as reishi, lion's mane, and chaga, are known to boost immunity, fight tumours, lower inflammation, and support brain health. Additionally, research on psilocybin and other hallucinogenic mushroom compounds has shown promise in treating mental health issues and facilitating psychological growth. Mushrooms also possess the unique ability to break down waste materials through their enzymatic secretions and mycelial networks, allowing them to colonize and restore depleted soils, remediate pollution, break down plastics, and help curb climate change.
In summary, while mushrooms may appear quite different from humans, we share a closer kinship with them than with plants due to our shared genetic ancestry. This connection is further highlighted by the various similarities in biological processes and potential applications in human health and environmental sustainability.
