Principle
A microscopic water analysis predominately reveals
unicellular organisms. But occasionally you can also see groups of
algae that resemble a mulberry. They consist of a number of single
algae which are held together by mucilage. Such an assemblage is
referred to as a colony. The volvox alga constitutes an especially
large colony. This sphere (lat. volvere: to roll) is made of
several thousand cells which are surrounded by a mucilage sphere
and interconnected by plasma threads. All of these cells are
identical. They possess two flagellae and one chloroplast for
photosynthesis. Information is exchanged through the plasma
threads, for example, so that locomotion is achievable by a
synchronous beat of the flagellae. Volvox also possesses
several
reproductive cells which develop into daughter spheres extending
into the interior.
