Just add water to this special dry protozoan culture and in 24 hours you'll have your own living culture of mixed protists and algae to study. The culture will change each day as different protist species become more prevalent. Allow 3 days for the culture to fully mature, but study it each day. Not only will the protists you find vary from day to day but you'll also find different protozoans at the top or side of the culture than at the bottom of the culture.
You can spend hours sampling this culture each day as you hunt for, identify, and study the habits of different protists. This complete kit includes the dry protist culture, a cup to use as a hatching container, food, identification key, and instructions. We recommend plain microscope slides and coverslips to observe these organisms with your X microscope. Ideas for Science Fair Experiments: What are the effects of light and temperature on protists?

While we typically think of microorganisms as being unicellular, there are also many multicellular organisms that are too small to be seen without a microscope. Some microbes, such as viruses, are even acellular not composed of cells. Microorganisms are found in each of the three domains of life: Archaea, Bacteria, and Eukarya. Microbes within the domains Bacteria and Archaea are all prokaryotes their cells lack a nucleus , whereas microbes in the domain Eukarya are eukaryotes their cells have a nucleus.
Some microorganisms, such as viruses, do not fall within any of the three domains of life. In this section, we will briefly introduce each of the broad groups of microbes. Later chapters will go into greater depth about the diverse species within each group. How big is a bacterium or a virus compared to other objects? Check out this interactive website to get a feel for the scale of different microorganisms. Prokaryotic Microorganisms Bacteria are found in nearly every habitat on earth, including within and on humans. Most bacteria are harmless or helpful, but some are pathogens, causing disease in humans and other animals. Bacteria are prokaryotic because their genetic material DNA is not housed within a true nucleus. Most bacteria have cell walls that contain peptidoglycan. Bacteria are often described in terms of their general shape. Common shapes include spherical coccus , rod-shaped bacillus , or curved spirillum, spirochete, or vibrio.
Figure 2 shows examples of these shapes. Figure 2. Common bacterial shapes. Note how coccobacillus is a combination of spherical coccus and rod-shaped bacillus. Some bacteria are photosynthetic, such as oxygenic cyanobacteria and anoxygenic green sulfur and green nonsulfur bacteria; these bacteria use energy derived from sunlight, and fix carbon dioxide for growth. Other types of bacteria are nonphotosynthetic, obtaining their energy from organic or inorganic compounds in their environment. Archaea are also unicellular prokaryotic organisms. Archaea and bacteria have different evolutionary histories, as well as significant differences in genetics, metabolic pathways, and the composition of their cell walls and membranes. Unlike most bacteria, archaeal cell walls do not contain peptidoglycan, but their cell walls are often composed of a similar substance called pseudopeptidoglycan.
Like bacteria, archaea are found in nearly every habitat on earth, even extreme environments that are very cold, very hot, very basic, or very acidic Figure 3. Some archaea live in the human body, but none have been shown to be human pathogens. Figure 3. Some archaea live in extreme environments, such as the Morning Glory pool, a hot spring in Yellowstone National Park. The color differences in the pool result from the different communities of microbes that are able to thrive at various water temperatures.
Think about It What are the two main types of prokaryotic organisms? Name some of the defining characteristics of each type. Eukaryotic Microorganisms The domain Eukarya contains all eukaryotes, including uni- or multicellular eukaryotes such as protists, fungi, plants, and animals. The major defining characteristic of eukaryotes is that their cells contain a nucleus. Protists Protists are unicellular eukaryotes that are not plants, animals, or fungi. Algae and protozoa are examples of protists. Figure 4. Assorted diatoms, a kind of algae, live in annual sea ice in McMurdo Sound, Antarctica. Their cells are surrounded by cell walls made of cellulose, a type of carbohydrate. Algae are photosynthetic organisms that extract energy from the sun and release oxygen and carbohydrates into their environment. Because other organisms can use their waste products for energy, algae are important parts of many ecosystems.
Many consumer products contain ingredients derived from algae, such as carrageenan or alginic acid, which are found in some brands of ice cream, salad dressing, beverages, lipstick, and toothpaste. A derivative of algae also plays a prominent role in the microbiology laboratory. Agar, a gel derived from algae, can be mixed with various nutrients and used to grow microorganisms in a Petri dish. Algae are also being developed as a possible source for biofuels. Protozoa singular: protozoan are protists that make up the backbone of many food webs by providing nutrients for other organisms.
Protozoa are very diverse. Some protozoa move with help from hair-like structures called cilia or whip-like structures called flagella. Others extend part of their cell membrane and cytoplasm to propel themselves forward. Some protozoa are photosynthetic; others feed on organic material. Some are free-living, whereas others are parasitic, only able to survive by extracting nutrients from a host organism. Most protozoa are harmless, but some are pathogens that can cause disease in animals or humans Figure 5.
Figure 5. Giardia lamblia, an intestinal protozoan parasite that infects humans and other mammals, causing severe diarrhea. Some multicellular fungi, such as mushrooms, resemble plants, but they are actually quite different. Fungi are not photosynthetic, and their cell walls are usually made out of chitin rather than cellulose. Figure 6. Candida albicans is a unicellular fungus, or yeast. It is the causative agent of vaginal yeast infections as well as oral thrush, a yeast infection of the mouth that commonly afflicts infants. There are more than known species. Yeasts are found in many different environments, from the deep sea to the human navel. Some yeasts have beneficial uses, such as causing bread to rise and beverages to ferment; but yeasts can also cause food to spoil.
Some even cause diseases, such as vaginal yeast infections and oral thrush Figure 6. Other fungi of interest to microbiologists are multicellular organisms called molds. Molds are made up of long filaments that form visible colonies Figure 7. Molds are found in many different environments, from soil to rotting food to dank bathroom corners. Molds play a critical role in the decomposition of dead plants and animals. Some molds can cause allergies, and others produce disease-causing metabolites called mycotoxins. Molds have been used to make pharmaceuticals, including penicillin, which is one of the most commonly prescribed antibiotics, and cyclosporine, used to prevent organ rejection following a transplant. Figure 7. Large colonies of microscopic fungi can often be observed with the naked eye, as seen on the surface of these moldy oranges.
Think about It Name two types of protists and two types of fungi. Helminths Multicellular parasitic worms called helminths are not technically microorganisms, as most are large enough to see without a microscope. However, these worms fall within the field of microbiology because diseases caused by helminths involve microscopic eggs and larvae. One example of a helminth is the guinea worm, or Dracunculus medinensis, which causes dizziness, vomiting, diarrhea, and painful ulcers on the legs and feet when the worm works its way out of the skin Figure 8. Infection typically occurs after a person drinks water containing water fleas infected by guinea-worm larvae. In the mids, there were an estimated 3. In , there were only cases reported, thanks to the coordinated efforts of the World Health Organization WHO and other groups committed to improvements in drinking water sanitation.
Essentially, a virus consists of proteins and genetic material—either DNA or RNA, but never both—that are inert outside of a host organism. Viruses can infect all types of cells, from human cells to the cells of other microorganisms. In humans, viruses are responsible for numerous diseases, from the common cold to deadly Ebola Figure 9.
