Microorganism means small organism which is often referred to as a microbe. A microbe is a single-cell organism which is so tiny that millions can fit into the eye of a needle. Microbes are known to be the oldest form of live on Earth, they can live individually or cluster together in communities. Microbes live everywhere. Anywhere you can think of, microbes live. They can be found in the air, soil, water and are present in and on our own body. Microbes are also known to live at temperatures less than -20 degrees Celsius to temperatures hotter than the boiling point.
These tiny organisms include Bacteria, Archaea, Fungi and Protists. Bacteria and Fungi are a commonly known form of microbe unlike Archaea which are similar to bacteria but

Hyphae are very tiny and grow at the tip, dividing repeatedly along their length which create long, branching chains. The Hyphae will keep growing until a network of threads is formed. This is called a mycelium. It is less common yet still possible for fungi to produce spores sexually. Two mating cells from hyphae of different strains of fungi can fuse together and form a spore stalk, this is mating. The spores eventually burst causing the spores to drop in the same area or be carried by wind or rain to a new area. They will then germinate like seeds.
There are three things which subdivide fungi, one this is basis of their life cycles, another is the presence or structure of their fruiting body, and finally, the arrangement of and type of spores they produce. The three main groups of fungi are:
1) Multicellular filamentous moulds
2) Macroscopic filamentous fungi that form large fruiting bodies. This group is often referred to as “mushrooms” however, this is just a small part of the fungus we see above the ground.
3) Single celled microscopic yeasts
Mould, is a common type of fungus being known all around the world, it is the little dusty spots found spreading over food and other things in a person’s home. Moulds are microscopic organisms, they too are alike plant organisms. They are composed of long filaments called hyphae. Mould collects its food from its surroundings as well as displays themselves in a variety of
Most members of the kingdom Fungi lack flagella; the structures are completely absent in all stages of their life cycle. The only
Yeasts are unicellular organisms belonging to the fungi kingdom and Eukarya Domain. Yeast are heterotrophs which gain its energy from enzymes that break down carbohydrates into alcohol and CO2. It can also derive energy from simple sugars such as fructose and glucose, which can be found mostly in groups and reproduce asexually (occasionally sexually). Asexual yeast reproduction is accomplished through a process called budding. Budding occurs when a yeast cell achieves full growth. It then sprouts a bud like swelling on its surface. Part of the parent cell’s nucleus is taken and put into this bud, which then is encased by a wall. The
Fungi are multi-celled organisms that form a third Kingdom of life, along with the plant kingdom and the animal kingdom.

Microbes are bacteria, archaea and eukaryotes. The earth was formed 4.6 million years ago. And a few million years later, by 3.5 billion years ago, earth was already inhabited by a diversity of organisms. The earliest organism is Prokaryotes and within the next billion years, two distinct groups of prokaryotes called bacteria and archaea diverged. Eukaryotes cell evolved from a prokaryotes community, a host cell containing even smaller prokaryotes .The microbial world accounted for all known life forms for nearly 50 to 90% of Earth's history. We are still researching microbial organisms today in marine environment, extreme environments. A microbial observatory is an NSF-funded project dedicated to the discovery and characterization of novel microorganisms and microbial communities of diverse
4. Know the classification of fungal diseases (mycoses). 30% of known fungal species produce mycoses, which are fungal diseases of plants, animals, and humans. Classifications of fungi are; Zygomycota, Ascomycota, and Basidiomycota.
They are known as a diverse group of unicellular eukaryotic organisms. They are also defined as a single celled organism with animal like behaviour. Protozoa are microscopic cells that range from a size from 10 to 52 micrometers. Some protozoa are larger than most. For example the xenophyophores are around 20 centimetres in diameter. Free living forms are restricted to moist environments, such as soil, mosses and aquatic habitats. Many protozoa are symbionts.
Some fungi have a dikaryotic (two nuclei in one cell) stage, more commonly known as a heterokaryotic stage, because the fungus can wait for an opportune time to fuse the nuclei together and grow. The fungus would not want to grow rapidly in the diploid stage unless it had adequate food sources. This waiting will allow for maximum efficiency during its growth.
The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.
The Latin word for mushroom is fungus (plural, fungi). The word fungus has come to stand for a whole group of simple plants that contain no chlorophyll and lack such complex plant structures as roots, stems, leaves, and flowers. Included among the fungi, along with mushrooms, are molds, mildews, rusts, smuts, truffles, and yeasts. Toadstool is another name for mushroom. Some people use the name toadstool only when referring to poisonous mushrooms, but botanists make no such distinction. A general scientific term for fungi is mycota, from the Greek word for mushroom, mykes, and the study of these organisms is called mycology.
What Mold Is: Mold is a type of fungus that decomposes organic material. It is normally green, black, or blue in color. While you can usually detect mold growth with the naked eye, mold spores are microscopic.
Molds are eukaryotic (taxonomic group that includes organisms composed of one or more cells with visible nuclei and organelles) micro-organisms that are decomposers of dead organic material such as leaves, wood and plants. Mold grows by the extension of hyphae, which are considered to be tiny root hairs that extend across surfaces. In this way, small colonies of mold can expand to cover many square feet of material and it can also create spores that allow mold to inhabit the air and spread across various locations. (Moreau, 1974, p.125). The spores and hair-like bodies of individual mold colonies are too small for humans to detect without a microscope. These spores can survive in various conditions, such as hot, cold, dry and moist, and allows mold to grow. When spores are released they can be carried by air or water to new locations. According to Christensen (1975), some spores are so small that they are more affected by air currents than by gravity as it allows them to reach further locations. When spores land on a damp surface that has food and oxygen available, and the proper temperature, they will start to grow. Mold spores are ubiquitous in nature and are present everywhere, in outside air as well as indoor air. Wherever there is decomposing organic material mold and its spores are also present, which makes it
In “Looking at mushrooms”, they tell how mushrooms live, function, decompose, and how they help the enviorment. In the pharagraph of “How Fungi Function” it list all the roles and states, “Some are decomposers, some form partnerships with living plants, and some are parasites.” This text cited goes on telling about the individual fungi role, function, and what the mycologist studying them has to say about it. In the other hand, Charlene Brusso and her passage only exclaims 1 fungi type and goes on about its uses, not its function and therefore she doesn’t have a clear description of the fungi and needs to talk more of its discoveries.

Today her first question is: What are the three different types of microorganisms? The three main types of microorganisms include bacteria, fungi, and protists. The next question on her list is: What characteristics do the three types of microorganisms have? Bacteria are so small that they can only be seen with a microscope. They come in three shapes bacilli, cocci, and
