In taxonomy the Volvocales also known as Chlamydomonadales are an order of flagellate or pseudociliate green algae specifically of the Chlorophyceae. Volvocales can form planar or spherical colonies. These vary from Gonium (4 to 32 cells) up to Volvox (500 cells or more). Each cell has two flagella and is similar in appearance to Chlamydomonas with the flagella throughout the colony moving in coordination.[citation needed]Both asexual and sexual reproduction occur.
