What are archae (or archaebacteria)? How do they get their food? Where are they found? Are there any good websites for students about them?
Question Date: 2004-03-19
Answer 1:

The Archaea are a group of unicellular prokaryotic (they have no cell nuclei) organisms, separated by their biochemistry and structure of cellular organelles from the rest of bacteria.

Some taxonomists regard them as a kingdom, a sub-kingdom, or something even larger than a kingdom. Most are anaerobic and are killed by oxygen. They are well-known for living in extreme environments,including hot springs, supersaturated salt solutions,and inside the guts of some animals (including humans). Their methods of getting food are as varied as more normal bacteria, but include fermentation,chemosynthesis, etc.

Answer 2:

Archaea are like bacteria - they are single cells that don't have a nucleus - but they have enough differences from bacteria to be classified all by themselves.

They do things pretty much like bacteria in general - they transport food molecules into themselves through protein pumps or channels in their outer membranes. A lot of them live in really extreme environments, where nothing else can live.

I'm writing a paper now about one type of archaea that can live in boiling water. They are unusual because they assemble a network of tiny tubes outside of themselves. The archaea cells live in the spaces between the tiny tubes, and the colonies of archaea and tubes look like flakes in the liquid where they're growing.

Here's a nice site: archaea

Answer 3:

The Archae are the extreme survivors. Here is some good website.
