Fungal dispersal mechanisms
By: Danielle Dusold
The Fungi Kingdom presents a variety of spore types that utilize mechanisms that are not seen in any other group of organisms. Chytridiomycoda, Blastiocladiomycota, Neocallimastigomycota, Ascomycota, Zygomycota, Glomeromycota, and Basidiomycota make up the major phyla of fungi. Sexual and asexual spores of these fungi are...

The atmosphere of the earth was not always oxygen rich. When the first microorganisms appeared, perhaps 3.8 billion years ago, it was in a volcanic atmosphere of nitrogen, carbon dioxide, water vapor, methane, and ammonia. There was essentially no free oxygen. So these microorganisms...
Molecular biology techniques: RNA interference
By: Danielle Dusold
RNA interference, or RNAi, is an RNA-dependent mechanism that silences genes. RNAi is important in the gene silencing of developmental genes and show great potential for numerous fields of research. RNAi is commonly used to understand the function of genes in development, disease progression, reproduction...
Photosynthesis in common single-celled algae
By: Shawn Bailey
Algae are the world's solar panels. Although they harness less than half as much energy from the sun as solar panels, life would be hard pressed to continue without them. Algae, the base foundation for waterborne food chains, use photosynthesis to convert the sun's energy...
Photosynthesis in common single-celled algae
By: Megan Worley
Algae are plant organisms that contain chlorophyll and use that and other pigments to capture the energy from sunlight and convert it into food molecules. The process through which that is complete is called photosynthesis. Algae generally store those food molecules in a form of...

Serial analysis of gene expression (SAGE) is a technique that is used by microbiologists to obtain the expression data for many genes as well as identifying the genes that are expressed. Gene expression is particularly important because it determines the characteristics of individual organisms.The...

When RNA was first discovered, it was thought to be purely a messenger for DNA, a molecule that carried the DNA's commands. However, mRNA, messenger RNA, is only one of many types of the RiboNucleic Acid that performs a multitude of tasks in the cell...
Photosynthesis in common single-celled algae
By: Anne StClair
Algae are aquatic organisms that carry out photosynthesis. They live in fresh and salt water, and can also live in or on plants and in the soil if there is enough moisture. Many algae consist of a single cell and can be as tiny as...

Bacteriology is a field of microbiology which deals with the study of bacteria. This field also includes the study of the structure, specific functions and the corresponding actions of the bacteria on living organisms. There are specific characteristics that classify microorganisms into bacteria.Bacteria have...
The history of microbiology
By: Danielle Dusold
Before there were computers, cars, cell phones, hospitals, even humans all together, there were microbes. Microbes have played a huge role in the history of mankind and continue to be a major player in medicine, food and drug development, and disease. Evidence of microbiology can...
