The classification of algae is complex and somewhat controversial, especially concerning. the blue-green algae (Cyanobacteria), which are sometimes known as blue-green. bacteria or Cyanophyta and sometimes included in the Chlorophyta. These topics are. not covered in detail this document.
The nonmotile coccoid and colonial green algae belong to the Divisions Chlorophyta and Streptophyta. The Chlorophyta includes a diversity of taxa (morphologically and ecologically), ranging from unicellular and freshwater taxa (e.g., Chlamydomonas) to multicellular and marine taxa (e.g., Ulva).ollecting planktonic nonmotile coccoid and colonial green algae is rather easy and straightforward. Because they are suspended in the water column, a plankton net with a mesh size of 10 Î¼m is adequate for most taxa (nanoplankton and net plankton).
