The fungi comprise a diverse group of organisms that are heterotrophic and typically saprozoic. In addition to the well-known macroscopic fungi (such as mushrooms and molds), many unicellular yeasts and spores of macroscopic fungi are microscopic. For this reason, fungi are included within the field of microbiology.
Some fungi are dimorphic, having more than one appearance during their life cycle. These dimorphic fungi may be able to appear as yeasts or molds, which can be important for infectivity.

Because fungi are eukaryotic organisms, they have a distinct nucleus surrounded by a nuclear membrane. These are separated from plants on the basis of the presence of chitin in the cell wall and the absence of chlorophyll.
Fungal cells also contain mitochondria and a complex system of internal membranes, including the endoplasmic reticulum and Golgi apparatus. Unlike plant cells, fungal cells do not have chloroplasts or chlorophyll. Many fungi display bright colors arising from other cellular pigments, ranging from red to green to black.
Microfungi or micromycetes are fungi—eukaryotic organisms such as molds, mildews and rusts—which have microscopic spore-producing structures. They exhibit tube tip-growth and have cell walls composed of chitin, a polymer of N-acetylglucosamine.
Fungi are more complicated organisms than viruses and bacteria—they are "eukaryotes," which means they have cells. Of the three pathogens, fungi are most similar to animals in their structure.
The cell wall is a characteristic structure of fungi and is composed mainly of glucans, chitin and glycoproteins.
Fungi are eukaryotic microorganisms. Fungi can occur as yeasts, molds, or as a combination of both forms. Some fungi are capable of causing superficial, cutaneous, subcutaneous, systemic or allergic diseases. Yeasts are microscopic fungi consisting of solitary cells that reproduce by budding.
In addition to the well-known macroscopic fungi (such as mushrooms and molds), many unicellular yeasts and spores of macroscopic fungi are microscopic. For this reason, fungi are included within the field of microbiology. Fungi are important to humans in a variety of ways.
Examples: Yeasts (Torula spp. *, Candida albicans*, Saccharomyces cerevisiae), molds (Aspergillus flavus*, Penicillium notatum*, Cladosporium fulvum*, Cephalosporium acremonium*). 3.
The introduction to this website explained the difference between macrofungi and microfungi. The macrofungi are those that produce the easily visible fruiting bodies such as mushrooms, puffballs, polypores and so on - while the microfungi are the moulds, plant rusts, smuts, mildews and so on.
Bacteria and fungi are two types of microscopic organisms. The main difference between bacteria and fungi is that bacteria are unicellular prokaryotic organisms whereas fungi are multicellular eukaryotic organisms. Both bacteria and fungi contain DNA as their genetic material.
An organism that can be seen only through a microscope. Microorganisms include bacteria, protozoa, algae, and fungi. Although viruses are not considered living organisms, they are sometimes classified as microorganisms.
Characteristics of FungiFungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.They may be unicellular or filamentous.They reproduce by means of spores.Fungi exhibit the phenomenon of alternation of generation.Fungi lack chlorophyll and hence cannot perform photosynthesis.More items...
Characteristics of Fungi. Fungi have well-defined characteristics that set them apart from other organisms. Most multicellular fungal bodies, commonly called molds, are made up of filaments called hyphae. Hyphae can form a tangled network called a mycelium and form the thallus (body) of fleshy fungi.
Fungi are important in other ways. They act as decomposers in the environment, and they are critical for the production of certain foods such as cheeses. Fungi are also major sources of antibiotics, such as penicillin from the fungus Penicillium.
Hyphae can form a tangled network called a mycelium and form the thallus (body) of fleshy fungi. Hyphae that have walls between the cells are called septate hyphae; hyphae that lack walls and cell membranes between the cells are called nonseptate or coenocytic hyphae) (Figure 1). Figure 1. Multicellular fungi (molds) form hyphae, which may be ...
Additionally, whereas animals have cholesterol in their cell membranes, fungal cell membranes have different sterols called ergosterols. Ergosterols are often exploited as targets for antifungal drugs.
The Ascomycota include fungi that are used as food (edible mushrooms, morels, and truffles), others that are common causes of food spoilage (bread molds and plant pathogens), and still others that are human pathogens. Ascomycota may have septate hyphae and cup-shaped fruiting bodies called ascocarps.
Haploid fungi form hyphae that have gametes at the tips. Two different mating types (represented as “+ type” and “– type”) are involved. The cytoplasms of the + and – type gametes fuse (in an event called plasmogamy), producing a cell with two distinct nuclei (a dikaryotic cell). Later, the nuclei fuse (in an event called karyogamy) ...
The fungi are very diverse, comprising seven major groups. Not all of the seven groups contain pathogens. Some of these groups are generally associated with plants and include plant pathogens. For example, Urediniomycetes and Ustilagomycetes include the plant rusts and smuts, respectively.
two mushrooms that are near each other will have their hyphae intertwine and exchange DNA to create a new mushroom. Conidia. Asexual fungi spores of Ascomycetes. Plasmogamy. in fungi, the fusion of the cytoplasm of cells from two individuals; occurs as one stage of sexual reproduction, followed later by karyogamy.
Aseptate. Fungal hyphae which lack cell walls between adjacent cells are referred to as aseptate. Septate. Fungal hyphae which have cell walls between adjacent cells are referred to as septate.
A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. Meiosis. 1. Starts with 1 cell then splits twice.
