Caption

Light microscopy of Volvox colonies. Volvox is a chlorophyte, a type of green algae, that forms spherical colonies. The individual cells are similar to the alga Chlamydomonas, are flagellated, and they co-ordinate their beating to direct the colony towards light, which they detect using eyespots. They are common in freshwater habitats. The enclosed smaller spheres are the daughter colonies of the larger parent, which are released when they are large enough. Filmed with Darkfield illumination.
