Prokaryotic cells can have a variety of surface appendages - flagellum, fimbria or pilus - that enable them to move, adhere to surfaces and even infect host cells.

This collection of articles provides basic information about prokaryotic and eukaryotic cells, their structure, function, differences and similarities.

There are only two basic types of cells, primitive prokaryotes and the more complex eukaryotes. Here are the main features that distinguish these cell types.

Archaea are prokaryotes that differ from bacteria and eukaryotes enough to be assigned to their own taxonomic domain. Here is a brief introduction to Archaeans.

The distinction between species of sexually reproducing organisms is quite clear, but how are the lines drawn for organisms, like bacteria, that reproduce as clones?

Prokaryotes are evolutionarily ancient, for billions of years the only form of life. Here's a summary of the basic "parts & pieces" of these primitive cells.

The production of energy from organic compounds by oxidation using chemical (usually organic) compounds from within a cell as "electron acceptors" is called fermentation.

From the smallest bacterium to the largest plants and animals they are foundational and basic - they are cells. Explore cell uniqueness, similarities and differences.

The amount and location of peptidoglycan in the prokaryotic cell wall is what determines whether a bacterium is Gram-positive or Gram-negative.

The eukaryotic cells of plants and animals possess several critical differences from prokaryotic cells, including a nucleus and other membrane-bound organelles.

See the structure, nature and function of ribosomes - cell organelles essential for life. Ribosomes work with messenger RNA to manufacture all necessary cell proteins.

Cells that are small and primitive, or large and more complex, are organized to promote their sustenance and survival. Even the simplest of cells are very complex.

All living things are composed of one or more cells. Unlike cells, viruses, viroids and prions are acellular, nonliving parasites that require a living host to reproduce.

Most bacteria have one of these two types of cell walls. The differential Gram stain uses two dyes to distinguish between bacteria based on cell wall structure.

A look at the structural components of eukaryotic and prokaryotic cells and the differences between the two types of cell.

The mechanisms of inhibition of bacterial protein synthesis become clearer each year. The recent Nobel Prize in Chemistry rewarded the clearer understanding of ribosomes.

Infectious disease can result of cellular organisms, such as bacteria (prokaryotes), from eukaryotes (cells like ours) or from nonliving infectious agents.

Whether you know it or not, eukaryotic cells are the tiny units of life that make up your entire body. Read on and learn more about yourself!

Genetics is concerned with how traits are passed on through generations. This information, genetic material, is stored inside cells, working units that make up organisms.

Some living things reproduce by cloning; producing offspring that are genetically identical to the parent. Organisms that procreate sexually create genetic novelty.

Studying cell biology doesn't have to suck. Here's a fun and fascinating summary of how the cells of your body work to keep you alive and healthy.

All organisms are made up of cells. There are single-celled and multi-celled organisms. Here is a brief overview of what a cell consists of, and some of its functions.

The electron transport chain is the most complex and productive pathway of cellular respiration. Here is a straightforward, simplified explanation of how the ETC works.

Animals and plants are eukaryotes, composed of cells that have a nucleus, and membrane-bound organelles. But animal cells have a few different features than plant cells.

Gram- bacteria stain pink due to the location of cell wall peptidoglycan and an external LPS membrane. Here's how Gram staining identifies Gram negative organisms.

Gram + bacteria stain purple due to the chemistry and structure of their peptidoglycan cell wall. Here's how Gram staining identifies Gram-positive organisms.

Many science students are looking for short-cuts to make learning cell biology effortless. There are none, but there are strategies to help compare the two cell types.

When many hear the word "paleontology," images of massive dinosaurs come immediately to mind. However, it is the tiny microfossils that form the base of paleontology.

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do macrolides destroy bacteria without hurting our cells?

Deoxyribonucleic acid (DNA), the key component of living cells, is presented here in an overview.

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do quinolones destroy bacteria without hurting our cells?

Gram staining involves the application of a series of dyes that leaves some bacteria purple (Gram +) and others pink (Gram -). Here's how the Gram stain works.

Pneumonia is an inflammation or infection of the lungs most commonly caused by a bacteria or virus, but can also be caused by inhaling foreign substances.

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do aminoglycosides destroy bacteria without hurting our cells?

Both plant and animal cells are eukaryotic, with many similarities, but there are also key differences between the cells of plants and animals. Here is a summary.

What is cell metabolism? Obtaining food and converting it to energy is one of the features of life. This happens within animals, plants and individual cells.

Ribosomes, which can be free floating in the cell or attached to endoplasmic reticulum, carry out the steps of protein synthesis in the cell.

Some bacteria have an additional layer outside of the cell wall called the glycocalyx. This coating of macromolecules protects the cell and helps it adhere to surfaces.

These small creatures could have descended from either simplified animals or complex protozoans - but new research suggests that they might be a mixture of both.

There is an ordered regularity to the pandemonium of life on Earth.

Acid fast staining involves the application of a series of dyes that leaves some bacteria pink (Acid-fast) and others purple (Nonacid-fast). Here's how this stain works.

Although bacterial reproduction results in the generation of clones, prokaryotes can undergo genetic recombination through transformation, transduction, and conjugation.

Endospore staining involves application of a series of dyes. Malachite green stains endospores and safrinin dyes vegetative cells pink. Here's endospore stain procedure.

The stability of cell shape and structure are maintained by cytoskeletal proteins that interact with and transport required functional molecules.

Scientific classification sorts all life forms on Earth into five kingdoms: monera, protista, fungi, plantae, and animalia. Together they form the tree of life.

Horizontal gene transfer, also called lateral gene transfer, is a mechanism for evolution that goes beyond typical Darwinian theory.

When a cell requires more of a specific protein, messenger RNA is made from the gene for that protein and during translation the information is converted to new protein.
