Algae are not quite plants. They use photosynthesis to make food from sunlight, water, and carbon dioxide, the way plants do, and they use the same organelle to do it, the chloroplast. However, algae are simpler than plants. They are mostly single celled, though they...

For billion of years the earth existed without any life form. It was only after several billion years more that the first bacteria appeared in the form of archaeans and cyanobacteria. In a later date, humans (Homo sapiens) came to existence when the earth had...

In general, microbiology is the study of microorganisms, living things that cannot be seen with the naked eye. Some of these microbes include fungi, protists and bacteria. A number of sub branches of study are included in this general term, including virology, mycology, and parasitology...

Microbial physiology is a subgroup of the study of microbiology. This division, however, studies the biochemical functions of microbial cells. Microbial physiology examines microbial growth, metabolism and cell structure. Like other areas of microbiology, microbial physiology has interested people for hundreds of years. Initially, microbial...

Fungi are eukaryotic organisms that could be found in air, water and soil. They can be harmful or harmless. They are often called the "garbage disposers" because they feed on rotting, organic matter in the environment.Fungi dispersal mechanisms differ in some ways for each...

Microorganisms are the foundation of the cycles that take the essential elements of life from the environment to any organism and back again. Tiny as they are, microorganisms are the engines that keep the wheel of life turning. The Carbon Cycle This cycle takes carbon...
A look at microbial physiology
By: Effie Moore Salem
Learning how the microbes work is an ongoing process. Scientist learn one new thing and that opens up other possibilities. Microbial physiology is a science dealing with the makeup of microbes. It is part of the peculiar and important makeup of the living cells that...
The importance of microorganisms in the Earth's ecosystems
By: Effie Moore Salem
The importance of leaning what makes us sick makes up a great part of the study of microbiology. Microorganisms can make us sick, cure us, clean up our dirty waste, and work tirelessly for us and often without our knowing of what they are up...
The diverse functions of RNA
By: Divya Mohan
RNA is the little known cousin of DNA. Standing for Ribonucleic Acid, RNA is mainly different from DNA in the sugar (ribose) that makes up its backbone. DNA is famous for being the code for life, but in fact it is a code for making...
