Light micrograph of Volvox colony containing several asexual daughter colonies. Volvox is an organism that lies between the plant & animal kingdoms, being variously classified with the green algae (plant) or the flagellates (animal). The colony contains hundreds or thousands of cells arranged at the surface of a watery matrix. The individual cells have two flagella & eyespots. They reproduce both asexually & sexually. In the former case cells in the rear of the colony divide to form daughter colonies. Once released the parent colony dies. In the latter case male & female gametes are produced & a sexual union occurs. Magnification: X40 at 35mm size.
