What are the main types of algae?

Aug 31 2020

There are two basic types of algae, macroalgae and microalgae. The key difference between macroalgae and microalgae is that macroalgae are large and multicellular aquatic photosynthetic plant-like organisms, most people call it seaweed, while microalgae are small and unicellular aquatic photosynthetic plant-like organisms. It is estimated that there are about 800,000 species of algae, but only about 50,000 have been identified.
