Algae are one of the most important photosynthesizing organisms on Earth. They capture more of the sun's energy and produce more oxygen as a byproduct of photosynthesis than all plants and trees combined.

They come in all different sizes and shapes.

Some are motile

Chaetophora- branching algae

Desmids- possibly Closterium

Desmids (or Desmidiaceae) are single-celled green algae which can only be found in fresh water.

Hydrodictyon- these are cool, they form ring like branches and nets

Pediastrum

Scenedesmus

Did you know they can even grow in snowbanks?

Here is red algae from the tops of a glacier in Alaska near Juneau

Most green algae contain two forms of chlorophyll, which they use to capture light energy to fuel the manufacture of sugars
