Members of the kingdom Bacillariophyta are the diatoms. They are unicellular organisms that have cell walls, or tests, that are made of silicon dioxide and composed of two valves, which fit together with the help of a set of girdle bands. Most are photosynthesizers and they are important members of the marine plankton. There are about 10,000 known species.
