infinity-imagined: Scanning electron micrographs of diatoms, microscopic algae that form the base of the food chain and produce of Earth’s oxygen. The beautiful base of the pyramid of biology, feeding our air, land and life.

Diatoms, SEM - Stock Image B305/0371 - Science Photo Library The diatoms are a group of photosynthetic, single-celled algae containing about 10,000 species. They form an important part of the plankton at the base of the marine and freshwater food chains. The characteristic feature of diatoms is their intricately patterned, glass- like cell wall, or frustule. The frustule often has rows of tiny holes, known as striae.
