The Chlorophyceae are a class of green algae, distinguished mainly on the basis of ultrastructural morphology. They are usually green due to the dominance of pigments chlorophyll a and chlorophyll b. The chloroplast may be discoid, plate-like, reticulate, cup-shaped, spiral or ribbon shaped, depending on the species. Most of the members have one or more storage bodies called pyrenoids located in the chloroplast. Pyrenoids contain protein besides starch. Some algae may store food in the form of oil droplets. Green algae usually have a rigid cell wall made up of an inner layer of cellulose and outer layer of pectose.
This list of genera in Chlorophyceae is sub-divided by order and family. Some genera have uncertain taxonomic placement and are listed as incertae sedis . The list is based on the data available in AlgaeBase, the Integrated Taxonomic Information System (ITIS) and other taxonomic databases.
