Caption

Light micrograph of a colony of Volvox containing one small asexual daughter colony. It is seen among filamentous algae. Volvox is an organism that lies between the plant & animal kingdom, being classified either with the green algae (plant) or flagellates (animal). The colony contains from hundreds to thousands of cells arranged at the surface of a watery matrix. The individual cells have two flagella & eyespots. They reproduce 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 & sexual union occurs.
