Cyanobacteria - Definition, Glossary, Details - OilgaeIntroduction to the Cyanobacteria - Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.Links
Fossil Record of the Cyanobacteria - Cyanobacteria are among the easiest microfossils to recognize. Morphologies in the group have remained much the same for billions of years, and they may leave chemical fossils behind as well, in the form of breakdown products from pigments. Small fossilized cyanobacteria have been extracted from Precambrian rock, and studied through the use of SEM and TEM (scanning and transmission electron microscopy).
Cyanobacteria - From Wikipedia - Cyanobacteria, also known as blue-green algae, blue-green bacteria or Cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis. The name cyanobacteria comes from the color of the bacteria (Greek: κυανός (kyanós) = blue). They are a significant component of the marine nitrogen cycle and an important primary producer in many areas of the ocean, but are also found on land.
What is Cyanobacteria? - Cyanobacteria are prokaryotes (single-celled organisms) often referred to as lue-green algae. While most algae is eukaryotic (multi-celled), cyanobacteria is the only exception. Cyanobacteria obtain their energy through photosynthesis.
