Types of Bacteria and Viruses

Foodborne illness is the term used when you are sick because of food and drink containing harmful bacteria, viruses, fungi, parasites, toxins or natural contaminants. It s often referred to as food poisoning. If you think you have an illness caused by food, seek medical attention from your doctor. Symptoms of foodborne illness Symptoms may include: nausea or vomiting…

Cells Parts and Descriptions

Britannica Lists & Quizzes Wilfredo R. Rodriguez H. Think back to your high school biology class. Do you still remember the names and functions of all those little cell parts? A little foggy on the details, perhaps? Here’s a quick refresher course of some of the major eukaryotic organelles to keep your science skills sharp. It might come in handy for your…

Prokaryotes, Eukaryotes, and Viruses

A | A rank–abundance curve showing marine prokaryotes and eukaryotes. The most abundant organisms in the ocean, such as SAR11, are probably K-selected organisms that have slow maximum growth rates but are resistant to viral lysis and grazing. By contrast, less abundant organisms, such as Roseobacter spp. and Vibrio spp., are capable of rapid growth but are highly…

Mitochondria in Bacteria

About 1.5 billion years ago, primitive bacteria took residence inside larger cells, resulting in an intimate relationship that would mold the evolution of more complex, multicellular beings. The bigger cell was eukaryotic, meaning it contained organelles - structures surrounded by membranes, but the prokaryotic bacterial cell had no such arrangement. The bigger cells…

Fungus is a Bacteria

Bacteria and fungi occur in all environments. In humans, these lifeforms can be harmless passengers, participate in beneficial biological processes, or cause disease. Bacterial and fungal infections affect people of all ages and range from minor to potentially life-threatening. Bacteria and fungi have similarities and differences that influence their disease-causing…

Microorganisms Found in soil

Soil organism any organism inhabiting the during part or all of its life. Soil organisms, which in size from microscopic cells that digest organic material to small mammals that live primarily on other soil organisms, play an important role in maintaining fertility, structure, drainage, and aeration of soil. They also break down plant and tissues, releasing stored…

Bacteria cell wall Diagram

The Gram positive cell wall has a thick peptidoglycan (orange red in this picture) layer outside the plasma membrane. There may be a gap or periplasmic space between the peptidoglycan layer and the plasma membrane. Various membrane proteins can be seen floating in the plasma membrane. Elongate molecules called teichoic acids intermesh with the peptidoglycan layer…

Where is the Cytoplasm found?

The intracellular fluid of inside a cell called the cytosol. It is separate from certain cell organelles such as the nucleus and the mitochondria. In eukaryotes, the cytoplasm is the content within a cell membrane minus the content in the cell nucleus. It is where many metabolic reactions occur, there are still others within organelles. In prokaryotes, cytosol is…

It is in the inference family of questions, but most strongly supported question stems are often less strict. In other words, the correct answer may be not be something that must be true, but is very close to it. This is a stimulus without a conclusion, which is often the case for inference questions. We are told that some organisms originate by one organism engulfing…

What are the Structures of bacteria?

Using high magnification imaging, a team of researchers has identified several never before seen structures on bacteria that represent molecular machinery. The research is published this week in the Journal of Bacteriology, published by the American Society for Microbiology. The study drives home the point that a wealth of information remains to be discovered even…

Ancient bacteria trapped in a state of suspended animation for 250 million years are the world s oldest living things, claim US scientists. The microbes are ten times older than any previously discovered living organism and may reopen the debate about the origins of life on Earth. The bacteria were found in salt crystals buried almost 609 metres (2, feet) below ground…

Cells Type of bacterial

Bacteria are prokaryotic, unicellular organisms. Bacteria are very small; so much so that 1 billion could fit on 1 square centimeter of space on the human gums, and 1 gram of digested food has 10 billion bacteria. Bacteria are the simplest living organisms. Previously they fell under the Kingdom Moneran, but now they fall into two different Domains: Archaebacteria…

Three Different Types of Bacteria

The microbes alter the gut so that only certain species can follow them. Whatever the cause of the different enterotypes, they may end up having discrete effects on people’s health. Gut microbes aid in food digestion and synthesize vitamins, using enzymes our own cells cannot make. Dr. Bork and his colleagues have found that each of the types makes a unique balance…

Viruses Bacteria Size

The amount and arrangement of the proteins and of viruses determine their size and shape. The nucleic acid and proteins of each class of viruses assemble themselves into a structure called a , or nucleocapsid. Some viruses have more than one layer of protein surrounding the nucleic acid; still others have a membrane (called an envelope), derived from the membrane…
