Articles related to "Archaea"

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.

Thought to be among the oldest organisms on earth, methanogens live in extreme environments and have adaptations allowing them to thrive in their harsh habitats.

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

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.

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.

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

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.

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.

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.

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.

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

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.

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.

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!

The field of animal systematics (or taxonomy) devises schemes for grouping (classification) and naming (nomenclature) animals.

Bacteriology had it wrong for the past 300 years. Bacteria don't live alone. They live collectively in layers of slime where they do their own thing but do it together.

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.

In 2011, a collection of organisms, representing Earth's three domains of life, will blast off on a 34-month journey to the Martian moon, Phobos, and back to Earth
