Plants and mushrooms are often grouped together, but they are fundamentally different. Mushrooms are a type of fungus, and fungi are more closely related to animals than plants. While plants and mushrooms are both multicellular organisms that play important roles in the ecosystem and can be used for medicinal purposes, they have different methods of obtaining nutrition. Plants have chlorophyll, which allows them to convert sunlight into energy and synthesize food through photosynthesis. Mushrooms, on the other hand, lack chlorophyll and cannot perform photosynthesis. They obtain their nutrition by breaking down organic matter through an underground network of threads called mycelium. Additionally, plants and mushrooms reproduce differently, with plants capable of both sexual and asexual reproduction, while mushrooms primarily reproduce through the release of spores.

What You'll Learn
Mushrooms are fungi, not vegetables, fruits, or meat
Mushrooms are a type of fungi, which is a biological kingdom that also includes moulds and yeasts. Fungi are not plants, and mushrooms are not vegetables or fruits. While mushrooms are cooked and eaten like vegetables, they are fundamentally different. All vegetables and fruits come from edible plants, and plants contain chlorophyll, which is used to convert energy from sunlight into carbohydrates. Mushrooms, on the other hand, do not contain chlorophyll; instead, they "steal" carbohydrates from plants.
Fungi are, in fact, more closely related to animals than plants. Molecular evidence shows that fungi and animals share a common ancestor and branched away from plants around 1.1 billion years ago. This ancestor was likely a single-celled organism with sperm-like characteristics that later developed a stronger cell wall. Fungi and animals are both dependent on other organisms for nutrition, whereas plants can produce their own food through photosynthesis.
Mushrooms are the fruit of the fungus, and as they grow, they open to release spores, which are the seeds of fungi. These spores are spread by the wind and start growing new mycelium colonies elsewhere. Mycelium is the fungal threads that sprout mushrooms and typically grow underground or on logs. The mushrooms we cook and eat are only a small component of the bigger, living, and growing part of the mushroom, which is usually underground.
While mushrooms are not vegetables or fruits from a biological standpoint, they are often treated as such in the culinary world. They are nutrient-dense, providing a lot of nutrition in very few calories, and are an excellent meat substitute due to their savoury flavour and meaty texture.

Fungi are more closely related to animals than plants
Mushrooms are the fruiting bodies of macroscopic filamentous fungi. Early taxonomists observed that fungi were immobile and had rigid cell walls, which led them to conclude that fungi were not animals and were more similar to plants. However, recent research has revealed that fungi are more closely related to animals than to plants.
For much of scientific history, fungi were classified as plants and were studied by botanists. The French entomologist René Antoine Ferchault de Réaumur, for example, described fungi pathogenic to insects as plant roots. The Mycological Society of America was also established while fungi were still considered plants. However, modern molecular and computational approaches have provided robust evolutionary histories that indicate organismal relationships and estimate when they diverged from common ancestors.
According to a 1993 study by Baldouf and Palmer, animals and fungi exhibit similarities in certain proteins that plants and bacteria do not have. They compared 25 proteins and their DNA sequences and found that animals and fungi are each other's closest relatives. This finding is supported by other researchers, who have concluded that animals and fungi share a common ancestor and branched away from plants around 1.1 billion years ago. Later, animals and fungi separated on the genealogical tree of life, making fungi more closely related to animals than to plants.
Furthermore, fungi and animals form a clade called opisthokonta, which is named after a single, posterior flagellum present in their last common ancestor. This posterior flagellum propels primitive fungal spores and animal sperm alike. Additionally, fungi lack chloroplasts, which are a defining feature of plants. These lines of evidence strongly suggest that fungi are more closely related to animals than to plants, despite historical classifications to the contrary.

Plants and mushrooms have different methods of obtaining nutrition
Plants and mushrooms are not closely related. In fact, mushrooms (fungi) are more closely related to animals than they are to plants. They branched away from plants around 1.1 billion years ago. Fungi do not have chloroplasts, which are a unifying feature of plants. They also lack chlorophyll, which is necessary for plants to make food.
On the other hand, mushrooms (fungi) are heterotrophic, meaning they obtain their nutrition by absorbing organic compounds from their environment. They do not ingest their food like animals do, nor can they manufacture their own food like plants. Instead, they feed by absorbing nutrients from their surroundings. They accomplish this by growing through and within their substrate, such as wood, cheese, soil, or flesh. Fungi have specialized structures called hyphae, which have a large surface area-to-volume ratio, allowing for efficient absorption of nutrients. These hyphae secrete digestive enzymes that break down the substrate into smaller molecules that can be absorbed as nutrients. Some fungi, known as saprotrophs, obtain their nutrients from non-living organic matter, such as dead and decaying plant or animal tissue. They play an important role in ecosystems by recycling organic materials back into the environment. Other fungi are parasitic, obtaining their nutrients from living hosts by breaking down their living tissue.

Fungi and plants have different reproductive methods
Plants and mushrooms have historically been grouped together, but mushrooms are actually the fruiting bodies of fungi. While plants and fungi share some similarities, they differ in their reproductive methods. Fungi reproduce by forming and releasing spores, which are usually single cells. These spores are produced either directly by asexual methods or indirectly by sexual reproduction. In asexual reproduction, a single individual gives rise to a genetic duplicate of the progenitor without a genetic contribution from another individual. This can occur through the fragmentation of the thallus, the body of a fungus, or through budding, which is when a bud develops on the surface of the yeast cell. In sexual reproduction, the fusion of two nuclei occurs when two sex cells unite.
Plants, on the other hand, reproduce through a variety of methods, including pollination, seed dispersal, and vegetative propagation. Sexual reproduction in plants involves the fusion of male and female gametes, typically from different individuals, although some plants can self-fertilize. Plants also have specialized reproductive structures, such as flowers, which are not present in fungi.
Fungi, including mushrooms, reproduce by releasing spores, which can be spread over large areas by wind or water. These spores can remain dormant for extended periods, waiting for the ideal conditions to germinate and develop into new fungal individuals. In contrast, plants typically reproduce through seeds, which are larger and more complex structures than spores. Plant seeds often contain stored food reserves and are dispersed by animals, wind, or water.
While both plants and fungi can reproduce asexually, their methods differ. In addition to budding and fragmentation, fungi can also reproduce asexually through simple cell division or fission, where a single cell splits into two daughter cells, which then continue to divide and form a population. Plants, on the other hand, exhibit asexual reproduction through methods like vegetative propagation, where new individuals are formed from runners, rhizomes, or bulbs, without the involvement of seeds or spores.
The reproductive strategies of plants and fungi reflect their distinct evolutionary histories and adaptations to their respective environments. Fungi, with their ability to produce vast quantities of spores and their simple asexual reproduction methods, are well-adapted to rapidly colonizing new substrates and exploiting nutrient sources. Plants, with their larger and more complex reproductive structures, have evolved strategies that often involve interactions with animals or other vectors for pollination and seed dispersal, leading to the diverse range of plant species we observe today.

Plants and mushrooms share some similarities
Plants and mushrooms have historically been grouped together, and while they are different in many ways, they do share some similarities.
Both plants and mushrooms are multicellular organisms that play important roles in the ecosystem. They both have protective cell walls that provide structure and support. The cell walls of plants are made of cellulose, while mushrooms have chitinous cell walls.
Plants and mushrooms also reproduce, although they do so in different ways. Plants can reproduce both sexually and asexually. Mushrooms, on the other hand, primarily reproduce through the release of spores. These spores are released from the fruiting body of the mushroom and can be dispersed over long distances by wind or water.
Another similarity between plants and mushrooms is their medicinal properties. Both have been used for medicinal purposes for centuries, with plants being used to create remedies for a wide range of ailments, from the common cold to more serious illnesses.
While plants and mushrooms do share some similarities, it is important to note that they also have significant differences, particularly in their methods of obtaining nutrition. Plants have chlorophyll, which allows them to convert sunlight into energy and synthesize food through photosynthesis. Mushrooms, however, lack chlorophyll and cannot perform photosynthesis. Instead, they obtain their nutrition by breaking down organic matter in the soil or on decaying matter using their mycelial network.
