How to Teach with Algae and Cyanobacteria

Phycology is the scientific study of all forms of algae, from the oceans’ microorganisms to their vast seaweed ecosystems. Also known as algology, phycology is a branch of life science; it might be unfamiliar to students at first, but it’ll grow on them.

Most people don’t know the importance of algae. However, a long slime ago (2.45 billion years to be exact), cyanobacteria or blue-green algae began producing oxygen and triggering the Great Oxidation Event (GOE).

Cyanobacteria conduct photosynthesis, which produces oxygen. Scientists postulate that cyanobacteria may have evolved into the chloroplasts in all plant cells today. So, whether you call it pond scum, or frog spittle, our lives totally depend on algae and cyanobacteria (just don’t drink or swim in water that has it)!  
 

Fun Fact: “alga” is singular, and “algae” is plural.  It seems simple, but even professionals commonly confuse these terms.


Scientists believe that algae in oceans, rivers, and lakes contribute about half of all the oxygen produced on the planet. In fact, Prochlorococcus (a genus of cyanobacteria) is the smallest photosynthetic organism on Earth but produces up to 20% of the oxygen in our entire ecosphere.1 Efficient little organisms, aren’t they! So, the next time you take a deep breath, thank algae and cyanobacteria for making it possible.
