What is a fungus and what is it called?

Fungus (fungus; eumycetes) are heterotrophs with eukaryotic and cell walls. There are many species, with more than 10,000 genera and more than 100,000 species reported. Except for a few lower types that are single-celled, most of the vegetative bodies are mycelium composed of slender tubular hyphae.

The hyphae of lower fungi have no septum, and the hyphae of higher fungi have septums, the former is called non-septal hyphae, and the latter is called septal hyphae. The most characteristic of the cell walls of most fungi is the presence of chitin, followed by cellulose. Common fungal organelles are:

nucleus, mitochondria, microsomes, ribosomes, vacuoles, lysosomes, vesicles, endoplasmic reticulum, microtubules, flagella, etc.; Common inclusions include liver glucose, crystals, liposomes, etc.

Fungi are generally further divided into three groups, namely yeasts, molds, and mushrooms (macrofungi), which belong to different subphyla. Macrofungi refer to fruiting bodies or sclerotia that can form fleshy or colloidal matter, most of which belong to the subphylum Basidiomycetes and a few to the subphylum Ascomycetes. Common macrofungi include shiitake mushrooms, straw mushrooms, enoki mushrooms, bisporus mushrooms, oyster mushrooms, fungus, white fungus, bamboo sunflower, morel mushrooms, etc.

They are not only an important class of mushroom vegetables, but also an important resource for the food and pharmaceutical industries.

Fungi are a large group of organisms that are neither animals nor plants. Some fungi are beneficial to humans, such as yeast, which is used in brewing and dough making, and is also part of the fungus.

But there are also some fungi that can invade the human body and cause corresponding lesions in the human body, such as athlete's foot is caused by fungal infection, and ringworm is also caused by fungal infection. In addition to involving relatively superficial parts of the human body, fungi can also involve internal organs and produce serious lesions, such as brain lesions, meningitis, encephalitis, lung lesions, such as pneumonia, and abdominal lesions, such as peritoneum.

Mainly saprophytic or parasitic plants.

Lacks chlorophyll and relies on spores to reproduce. Such as: yeast, mushrooms, etc.

A fungus is a eukaryotic, sporulating, chloroplast-free eukaryotic organism. Including molds, yeasts, truffles (i.e. mushrooms) and other mushrooms known to man, more than 120,000 species of fungi have been discovered as of 2020. Fungi are independent of animals, plants, and other eukaryotes and are in their own right.

The cells of fungi contain chitin and can produce spores through asexual reproduction and sexual reproduction.

How long the fungus has been on Earth is unknown, and there is no definite conclusion about the origin of the fungus. Some of the characteristics of fungi are similar to those of plants, but in some ways they are similar to those of animals. In the 80s and 90s of the twentieth century, according to the comparative study of the mode of nutrition, fungi were not plants or animals, but a separate group of organisms - the kingdom of fungi.

Bacteria and fungi both have the word "fungus" in their names, and they both belong to microorganisms, but they have many differences in the type, structure, size, proliferation mode and name of the organism.

Fungi: are organisms with eukaryotic and cell walls; Fungi, like bacteria and microorganisms, are decomposers, i.e., organisms that break down the organic matter of dead organisms. Fungi decompose organisms into various inorganic substances, which increases the fertility of the land.

There are also fungi that are used in food processing, such as yeast in bread and other processing, and fungi are also needed for winemaking. In agriculture, forestry and animal husbandry, fungi have a harmful side. Fungi can cause a variety of plant diseases, which can cause huge economic losses.

Bacteria: It is a kind of unicellular organism belonging to prokaryotic cells, with a small body and simple structure, no forming nucleus, no nucleolus and nuclear membrane, and no other organelles except nucleoproteins; Bacteria are widely distributed in soil and water, or live in symbiosis with other organisms. The human body also carries quite a lot of bacteria.

It is estimated that the total number of bacterial cells in the human body and epidermis is about 10 times the total number of human cells.

The nutritional mode of bacteria is self-managed and heterogeneous, among which heterogeneous saprophytic bacteria are important decomposers in the ecosystem, so that the carbon cycle can be carried out smoothly. Some bacteria fix nitrogen, which converts nitrogen into a bioavailable form.
