Freshwater diatoms, an algae, surrounded by some lime scale on aquarium glass.

Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragillaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stellate colonies (e.g. Asterionella). Diatoms are producers within the food chain. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, but usually consist of two asymmetrical sides with a split between them, hence the group name. Fossil evidence suggests that they originated during, or before, the early Jurassic Period. Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water quality.

Algae is being investigated as a feedstock for biodiesel.

Algae has so many Leaves! I know it does, but this was the first time I noticed in detail.

What makes Rose Atoll in National Marine Sanctuary of American Samoa rosy? Coralline algae! Pink coralline algae dominates the atoll's fringing reef, giving the reef a rosy hue.
