Light micrograph of a branching colony of the golden- brown alga Dinobryon sp. . The colony is composed of single-celled algae,each of which secretes a fine,transparent,cellulose sheath known as a lorica. Only the tips of the branches of the colony are inhabited; the bases are composed of old,abandoned sheaths. The cells are attached to the inside of the lorica by a contractile stalk. They possess two chloroplasts,two contractile vacuoles,an eyespot and two different types of flagellum. Various unidentified filamentous algae are also visible in the image.
