Image: Diatoms

Detailed Description

Diatoms are algae that reflect the biotic condition of streams, lakes and estuaries. Diatoms are important indicator organisms because they are sensitive to natural and human impacts, and monitoring their condition provides information about ecosystem health. Shown here is a live cell of Didymosphenia geminata, showing the golden brown chloroplast. A number of cells of Achnanthidium are attached to the mucilage stalk.
