A look at bacteriology
By: M E Skeel
The first person to see a bacteria was probably van Leeuwenhoek, who made the first microscopes in the late 17th century. His single lens microscope magnified an amazing 300x, enough to see bacteria as well as protozoa in pond water. From these humble beginnings, the...
The role of microorganisms in earth's evolution
By: M E Skeel
Microorganisms are so numerous and varied that they have served not one but many roles in earth's evolution. In the modern world, microorganisms are found everywhere and fulfill numerous roles. In the oceans, algae, protozoa and bacteria are the most numerous and important members of...
Fungal dispersal mechanisms
By: M E Skeel
Fungi move mainly by growing. The cells in fungal hyphae divide and grow and this stretches the hyphal threads out into the soil or whatever substrates the fungi are using. This is a good strategy for reaching nearby food sources but for long distance dispersal...

Anyone who has left sour cream or cottage cheese in the refrigerator too long can attest to the speed with which bacteria can grow. It seems that a colony of green, fuzzy gunk can appear overnight, spoiling your attempt to make your favorite dip at...
Fungal dispersal mechanisms
By: Barbara Stanley
By what means do fungi travel? Many fungal colonies begin as spores that are carried on the wind, making them a source of allergies every year. Once they find hospitable environments in which to grow, they settle down. If nutrients are available and the temperature...

Bacteriology is one of the many branches that fall under the blanket study of microbiology. This limb of microbiology specifically studies bacteria and their connection to other fields such as medicine, industry and agriculture. Like most areas of science, analyzing the relationship between bacteria and...
A look at bacteriology
By: Effie Moore Salem
Bacteriology is the study of bacteria, how it causes disease, how it help the body, and how to use the knowledge to better humanity. The study of bacteria has come a long way since these microorganisms were first discovered in 1674 by Antony Van Leeuwenhoek...

One theory of the evolution of microorganisms on earth is the Microevolution. It is believed that single- celled organisms began to mutate and undergo gene alteration to form other organisms. This gene alteration and mutation occurred because of the action of certain chemicals and radiation...
A look at algae's symbiotic relationships
By: Anne StClair
Algae are aquatic organisms that produce their own food from sunlight, carbon dioxide and water, through photosynthesis. They range in size from microscopic single-celled algae to the giant kelp, which can grow to over 60 m (200 ft) long. Most live free and independent lives...

Gene duplication is an event where a complete copy of one or more pieces of DNA, containing a complete gene, multiple genes or even an entire chromosome, is duplicated. As an evolutionary event, gene duplication occurs due to an error during meiosis, the step in...
