The Chlorophyceae, also known as chlorophycean algae, are one of the classes of green algae, within the phylum Chlorophyta. They are a large assemblage of mostly freshwater and terrestrial organisms; many members are important primary producers in the ecosystems they inhabit.
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.
In the smaller forms, typically all cells are involved, but larger forms have anterior vegetative and posterior reproductive cells. Sexual reproduction varies from isogamy (both genders produce flagellated gametes of equal size) to oogamy (one gender produces a much larger, nonmotile gamete).
Characiochloridaceae consists of solitary or rarely clustered cells, attached to a substrate via a stalk or other adhesive organ. Cells are heteropolar, ranging from egg-shaped to spindle- or pear-shaped, but also sometimes spherical. The adhesive part of the cell may be colored brown from iron compounds.
Chaetophorales is an order of green algae in the class Chlorophyceae. [1] Algae in the order Chaetophorales consist of filamentous, branched algae. The thalli have two parts, a prostrate and upright section and the filaments are variously branched. The algae are found in freshwater habitats or terrestrial habitats. [2]

Members of this class are coccoid green cells, with a diameter of 1.5–4 μm, found in marine waters, with one nucleus, one mitochondrion, and one chloroplast surrounded by two membranes, containing starch grain; their single chloroplast has chlorophylls a and b; they lack pyrenoid and flagella; and they have a layered cell wall.
Cell walls may also be covered in ridges, warts, and net-like structures. Cells contain one parietal chloroplast, containing one pyrenoid. [4] Desmodesmus species usually produce colonies of more than one cell, but single cells (unicells) may be found as well. [5] These single cells may be confused with Lagerheimia, a genus of single-celled ...
