Volvox daughter colony. Differential interference contrast microscope footage of a Volvox sp. daughter colony. Volvox are freshwater unicellular green algae that usually make up a larger spherical colony, which behaves like a multicellular organism. Daughter colonies are produced asexually inside the parent colony, which disintegrates to release them when they are mature. Individual Volvox cells have two hair-like flagella that protrude outwards and are used for colony locomotion.
