genus = "Pandorina""Pandorina" is a genus of green
algae composed of 8, 16, or sometimes 32 cells, held together at their bases to form a globular colony surrounded bymucilage . The cells are ovoid or slightly narrowed at one end to appear keystone- or pear-shaped. Each cell has twoflagella with two contractilevacuole s at their base, an eyespot, and a large cup-shapedchloroplast with at least onepyrenoid . The colonies coordinate their flagellar movement to create a rolling, swimming motion. "Pandorina" shows the beginnings of the colony polarity and differentiation seen in "Volvox " since the anterior cells have larger eyespots. Molecular sequencing has shown that pandorina ismonophyletic .External links
