A diatom frustule "Colour-enhanced image of a diatom frustule. The frustule is the silicon cell wall that acts as a skeleton to support the single-celled diatom. In this image only the frustule and none of the cell contents remain. Diatoms have chloroplasts and can use sunlight to produce food. They are a major component of plankton in both fresh and salt water."

LITTLE MAKERS Microscopic view of silica-encased phytoplankton
Diatoms are producers within the food chain. A unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide). [X]
These specimens were living between crystals of annual sea ice in McMurdo Sound, Antarctica.
