On the prokaryotic side, there are diverse forms of bacteria and a group generally termed blue-green algae. The key difference between cyanobacteria and algae is that cyanobacteria are a group of prokaryotic bacteria while algae are small eukaryotic plant-like organisms.. Photosynthesis is an extremely important process that converts the energy of sunlight into chemical energy of carbohydrates. Practice. Cyanobacteria is responsible for changing the environment on Earth, allowing it to support living organisms, plants, and algae that evolved throughout history. ADVERTISEMENTS: 3. green algae.

'Algae' is the term given to a large and diverse group of organisms that tend to be found in watery areas. Be sure to list the compound and the algal group that the compound comes from. In the span of several decades, the Kingdom Protista has been disassembled because sequence analyses have revealed new genetic (and therefore evolutionary) relationships among these eukaryotes. Here we have grouped algae with protozoa and slime molds in Protista because mthe majority of algae are unicellular, and even the multicellular algae are structurally simple compared to true plants. These pigments let them capture light and live in deep water. Moss vs Fern questions.
