Mushrooms are a type of fungus, and all fungi are classified as eukaryotes. This means that mushrooms are not prokaryotes. Mushrooms have a membrane-bound nucleus with DNA wrapped around histone proteins, which distinguishes them from prokaryotic cells, such as bacteria, which lack a nucleus and more complex internal structures.

What You'll Learn
Mushrooms are fungi
Mushrooms are a type of fungus. They are classified as eukaryotic, meaning their cells have a true nucleus and possess various membrane-bound organelles, distinguishing them from prokaryotic cells, such as bacteria, which lack a nucleus and more complex internal structures. Fungi, including mushrooms, belong to the kingdom Fungi, which encompasses a wide variety of organisms.
Mushrooms develop from a nodule, or pinhead, called a primordium, which is typically found on or near the surface of the substrate. They are formed within the mycelium, the mass of thread-like hyphae that make up the fungus. The primordium enlarges into a roundish structure of interwoven hyphae, called a "button". The button is surrounded by a cottony roll of mycelium, the universal veil, which ruptures as the egg expands. Many mushrooms lack a universal veil and therefore do not have a volva or volval patches.
Mushrooms are biologically distinct from plant- and animal-derived foods. They have a unique nutrient profile, containing nutrients found in both plants and animals, as well as some that are unique to fungi. For example, mushrooms contain the sterol ergosterol, rather than cholesterol, which is found in mammalian cells. They also contain chitin, a polysaccharide derivative of glucose also found in the exoskeleton of crustaceans and insects, and the unique amino acid ergothioneine, which is found in limited dietary sources.
The term "mushroom" is typically applied to those fungi that have a stem (stipe), a cap (pileus), and gills (lamellae) on the underside of the cap. However, the term is also used more loosely to describe the fleshy fruiting bodies of some Ascomycota, as well as other variations such as "bolete", "truffle", "puffball", "stinkhorn", and "morel". The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus, but the term also covers a wide range of other gilled fungi, with or without stems.

Fungi are eukaryotes
All living organisms are made up of either prokaryotic or eukaryotic cells. Prokaryotic cells are structurally simpler and lack a nucleus, whereas eukaryotic cells are more complex and possess a membrane-bound nucleus.
Mushrooms are a type of fungus, and fungi are eukaryotes. This means that mushrooms are also eukaryotes. Fungi are multicellular organisms, meaning they are made up of many cells. Each cell is complex and has a variety of functions.
Fungal cells have a membrane-bound nucleus with DNA wrapped around histone proteins. They also contain several unique structures, such as mitochondria and the endoplasmic reticulum, which perform specific functions necessary for the cell's survival and operation.
Fungi, including mushrooms, belong to the kingdom Fungi, which includes a wide variety of organisms, such as yeasts, molds, and toxic fungi. They can be found in almost any habitat, although most of them reside on land, primarily in soil or plant debris.
Some fungi are plant parasites that cause illnesses such as mildews, rusts, scabs, and canker. Certain fungal species can also affect animals, with examples including athlete's foot, ringworm, and thrush, which are human skin disorders.

Eukaryotic cells have a nucleus
Mushrooms are a type of fungus, and fungi are eukaryotic. Eukaryotic cells are those that contain a nucleus surrounded by a membrane, which is also called the nuclear envelope. This membrane protects the genetic material—the DNA—stored inside the nucleus. The nuclear membrane contains nuclear pores, which selectively allow only certain substances to pass through. The presence of a nucleus is the defining feature of eukaryotic cells, distinguishing them from prokaryotic cells, which lack a nucleus.
Eukaryotic cells are more complex than prokaryotic cells. They include all complex cells and almost all multicellular organisms, ranging from microscopic single cells to large animals and plants. Eukaryotic cells also contain several membrane-bound organelles, which are specialized cellular subunits that carry out specific cellular functions. Examples of organelles include the endoplasmic reticulum, the Golgi apparatus, and mitochondria. The endoplasmic reticulum is involved in protein transport and maturation, while mitochondria are cellular energy exchangers.
The origin of the eukaryotic cell, or eukaryogenesis, is a milestone in the evolution of life. Eukaryotes are thought to have evolved between about 1.7 billion and 1.9 billion years ago, with the earliest known microfossils resembling eukaryotic organisms dating to approximately 1.8 billion years ago. The last eukaryotic common ancestor (LECA) is the hypothetical origin of all living eukaryotes and was most likely a biological population, not a single individual.
Eukaryotic cells reproduce differently from prokaryotic cells. All eukaryotes undergo a process called mitosis, which is more complicated than the binary fission that prokaryotes use to reproduce. In sexually reproducing eukaryotic organisms, they can also undergo meiosis, creating genetically unique reproductive cells called gametes or sex cells that have half the number of chromosomes as the parent cells.

Prokaryotes lack a nucleus

Prokaryotes, on the other hand, are organisms whose cells lack a nucleus and other organelles. Prokaryotic cells are generally smaller and simpler than eukaryotic cells. They are surrounded by a plasma membrane but lack internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles is what differentiates prokaryotes from eukaryotes.
Prokaryotes are divided into two groups: bacteria and archaea. Most prokaryotes are small, single-celled organisms with a relatively simple structure. Their DNA is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. Prokaryotes carry a small amount of genetic material in the form of a single molecule or chromosome of circular DNA.
Eukaryotic cells, such as those found in mushrooms, have a true nucleus where the genetic material (DNA) is stored and protected. They also contain unique structures, such as mitochondria and the endoplasmic reticulum, which perform specific functions necessary for the cell's survival and operation.
The division between prokaryotes and eukaryotes is considered the most important distinction among organisms. This distinction reflects two very different levels of cellular organization. Eukaryotic cells are about 10,000 times larger than prokaryotic cells by volume, and their DNA is organized as linear rather than circular DNA molecules.

Mushrooms are not prokaryotes
Mushrooms are a type of fungus, and all fungi are classified as eukaryotes. This means that mushrooms are not prokaryotes.
Prokaryotic cells lack internal cellular bodies, whereas eukaryotic cells possess them. Eukaryotic cells, like those found in mushrooms, contain a nucleus where genetic material (DNA) is stored and protected. They also contain organelles, which are unique structures that perform specific functions necessary for the cell's survival. Prokaryotic cells, on the other hand, do not have a nucleus or the more complex internal structures found in eukaryotic cells.
Mushrooms, as part of the kingdom Fungi, encompass a wide variety of organisms, including edible mushrooms like Agaricus bisporus and common molds like Penicillium. Fungi can be single-celled or multicellular organisms with a great deal of complexity. They may be found in almost any habitat, although they primarily reside on land, especially in soil or plant debris.
The classification of fungi as eukaryotes is supported by scientific consensus in biological taxonomy, where fungi are grouped under the domain Eukarya due to their cellular features. Fungi are also characterized by their inability to photosynthesize, instead relying on absorbing nutrients from their environment.
In summary, mushrooms are not prokaryotes because they are a type of fungus, and all fungi are classified as eukaryotes based on their cellular structure and other distinctive characteristics.
