Mushrooms are unique organisms that are neither plants, animals, nor bacteria. They are part of the fungi kingdom, and the mushrooms we eat are the fruit of an underground fungus. Unlike plants, mushrooms do not make their food through photosynthesis. Instead, they absorb nutrients from their environment. They do this by first breaking down their food externally and then absorbing the nutrients through their cell walls.

What You'll Learn
Mushrooms are fungi, not plants
Fungi absorb organic compounds from their environment by first breaking down their food externally and then absorbing the nutrients. They do this by releasing digestive enzymes into the dead or living organic matter around them. These enzymes break down large organic molecules into smaller molecules that the fungi can then absorb through the cell walls of their thread-like hyphae.
Hyphae are the long, thread-like structures that make up the mycelium, a network that allows fungi to absorb minerals and nutrients. The large surface area of hyphae is well-adapted for efficient nutrient absorption. As fungi grow, they can access more organic matter and, therefore, more nutrition.
Different types of mushrooms feed on different sources of organic matter. Some feed on decaying organic matter like wood, plants, and even dead animals, acting as important decomposers in the ecosystem. Others feed on living host organisms, such as plants or animals, and obtain nutrients from them. This ability to obtain nutrients from their environment is what sets fungi apart from plants and highlights why mushrooms are classified as fungi rather than plants.

They absorb nutrients from their environment
Mushrooms are unique because they are not plants, animals, or bacteria. They are part of the fungi kingdom, which also includes yeasts, molds, mildews, rusts, and smuts. Fungi are heterotrophic, meaning they cannot make their own food like plants. Instead, they absorb nutrients from their environment.
Fungi absorb organic compounds from the environment around them. They first break down their food externally and then absorb it. They use long, thread-like hyphae that branch out and create a network called mycelium. The hyphae have a large surface area that is well-adapted for efficient nutrient absorption. The mycelium releases digestive enzymes into the dead or living organic matter around it. These enzymes break down large organic molecules into smaller, simple molecules that the hyphae can then absorb.
Different types of mushrooms feed differently and use specific organic materials or food sources to get their nutrients. Some feed on dead and decaying organic matter, such as wood, plants, and even dead animals. These mushrooms are known as saprotrophs or decomposers and play a crucial role in the ecosystem by breaking down this organic matter. Other mushrooms, such as parasite mushrooms, require a living host and can harm the host in the process. Endophytes are another type of fungi that require a host, but unlike parasites, they do not harm the host and can even provide benefits such as improved nutrient absorption and increased resistance to pests.
Fungi can absorb a variety of nutrients from their environment, including carbohydrates such as glucose and fructose, as well as more complex carbohydrates like cellulose, starches, and lignin. Some fungi can even absorb proteins to obtain carbon and nitrogen, and certain compounds like nitrates and ammonium. This ability to absorb and move nutrients through an ecosystem makes fungi an essential part of the natural world.

They break down large molecules into smaller ones
Mushrooms are part of the fungi kingdom, which also includes yeasts, moulds, mildews, rusts, and smuts. Fungi are heterotrophs, meaning they cannot make their own food like plants. Instead, they absorb nutrients from their environment. This is done by first breaking down large molecules into smaller ones and then absorbing the nutrients from the digested matter.
Fungi break down large molecules by injecting enzymes into organic matter. These enzymes digest the matter, breaking it down into smaller molecules that can be absorbed by the fungi. This process is essential for the fungi to obtain the nutrients they need to grow.
The enzymes released by fungi include cellulase, which breaks down cellulose, a major component of plant cell walls. Fungi also release hydrolytic enzymes that break down large organic molecules such as polysaccharides, proteins, and lipids.
The thread-like hyphae that make up the mycelium network of the fungi play a crucial role in this process. They have a large surface area that is well-adapted for efficient nutrient absorption. The hyphae release the enzymes into the organic matter, which begins the breakdown process. As the fungi grow, they can access more organic matter and, therefore, more nutrition.
Different types of mushrooms feed on different sources of organic matter. Some feed on dead plants or other decaying organic matter, acting as decomposers in the ecosystem. Others feed on living host organisms, such as plants or animals, and obtain their nutrients from the host.

They feed on dead and decaying organic matter
Mushrooms are unique in their ability to obtain food compared to other organisms. Unlike plants, which can make their own food through photosynthesis, mushrooms are heterotrophic, meaning they depend on other sources for their nutritional needs. This is because mushrooms lack chlorophyll, the pigment that gives plants their green colour and enables them to convert sunlight into energy.
So, how do mushrooms obtain their nourishment? The answer lies in their ecological role as decomposers. Mushrooms feed on dead and decaying organic matter, playing a crucial role in the breakdown and recycling of nutrients in ecosystems. They obtain their energy and nutrients from dead plants, fallen leaves, dead trees, and other organic materials that are in various stages of decomposition.
The thread-like structures called hyphae that make up the mycelium of a mushroom are responsible for this process. Hyphae secrete enzymes that break down complex organic compounds, such as cellulose and lignin, which are found in dead plant material, into simpler substances. These enzymes include cellulases and ligninases, which break down cellulose and lignin, respectively. The breakdown of these complex compounds results in the release of simpler molecules, such as glucose and other sugars, that the mushroom can then absorb and use for growth and metabolism.
This process of obtaining nutrients is called saprotrophic nutrition. It is a slow and gradual process, as the decomposition of organic matter by mushrooms can take weeks, months, or even years, depending on the environmental conditions and the type of organic material being decomposed. However, this process is essential for the ecosystem as it helps in the recycling of nutrients, ensuring that essential elements are returned to the soil, making them available for other organisms and contributing to the overall nutrient cycle.

Some feed off a living host
Mushrooms are unique in that they are not plants, animals, or bacteria. They are part of the fungi kingdom, which also includes yeasts, moulds, mildews, rusts, and smuts. Fungi are heterotrophic, meaning they rely on their environment for food and cannot produce their own.
Some mushrooms feed off a living host. Parasitic fungi, for example, can obtain nutrients from various sources, including carbohydrates like glucose and fructose, and more complex carbohydrates like cellulose, starches, and lignin. They can even absorb proteins to obtain carbon and nitrogen, as well as nitrates and ammonium compounds.
Mycorrhizae is another type of fungi that requires a host plant to grow and feed. Their mycelium, a network of thread-like structures called hyphae, taps into or wraps around the roots of plants to receive glucose. In turn, the fungi provide extra moisture and nutrients to the plant.
Endophytes are a type of fungi that rely on a host and invade the host's tissue like parasites. However, unlike parasites, the host remains healthy and even benefits slightly from the fungi, experiencing better nutrient absorption and increased resistance to pests.
Fungi have developed specialised structures for nutrient uptake from living hosts, which penetrate into the host's cells for nutrients.
