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

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.

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

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

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!

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

The cell's endomembrane system consists of the rough and smooth ER, Golgi apparatus, vesicles and plasma membrane, all working together to transport cellular materials.

Organelles allow for many of the different required functions of the eukaryotic cell to be performed in specialized subcellular structures.

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

A new study shows a strong correlation between longer life and low protein diets in Drosophila, or fruit flies. Low protein diets slow down mitochondrial degradation.

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.

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.

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.

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

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

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

This classroom activity can be used to familiarize students with basic cell structure and encourage them to think about how the membrane system of eukaryotes works.

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.

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.

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.

Plants are eukaryotes, composed of cells that have a nucleus, and membrane-bound organelles. But plants have a few different features than animal cells. Here's a summary.

Newly discovered cell-sized viruses have an infecting satellite virus, with implications for viruses as life forms, cell origins, the cause of disease and its treatment.

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.

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

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

Cellular respiration is the biochemical breakdown of a chemical substrate, such as glucose sugar, or fat, through oxidation.

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

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

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

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.

The term 'algae' covers many different organisms from plant-like seaweeds to unicellular diatoms. This can make an algae definition confusing.

Besides mediating between the DNA and proteins, RNA has a function in regulating the levels of proteins in the cell. This regulation is critical for the cell's behavior.

A definite asexual or sexual reproductive cycle is usually a prerequisite for the success of a species. Mycelia sterilia have found a way to do without either.

The cell nucleus may be the most important organelle in the cell for students to understand. It contains the DNA which controls nearly all cell activity inside the cell.

Extremophiles survive harsh conditions that would otherwise be unlivable. Studying them offers clues to evolution, adaptation and the possibility of life on other worlds.

More then just mold, fungi are the decomposers of the ecosystem. Once grouped with plants, fungi are actually more closely related to animals.

Glycolysis, synthesis of acetyl-CoA, Kreb's Cycle and electron transport are the complex series of reactions that turn the food we eat into energy.

What are deoxyribonucleic and ribonucleic acid made of, and how are these big molecules of genetic information built? This article explains the basics.

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 crystalline structure of ribosomes has been studied by three scientific groups and the group leaders have received the 2009 Nobel Prize for explaining ribosomes.
