Coccolithophores are single celled eukaryotic phytoplanktons that synthesize intricate exoskeletons from crystals of calcium carbonate. The functions of these coccoliths are relatively unknown. When nutrient and light conditions are optimal, coccolithophores can form massive plankton blooms that are visible from space. When large numbers of these organisms accumulate on the ocean floor they can form deposits of chalk, such as the White Cliffs of Dover.

Diatoms, an algae, are probably the smallest green plants in the world because many of them are made up of just one cell! When they die there glassy cases gather forming what we call diatomite which is collected and put in filters, scouring powders, and toothpaste.

Chalk. A coccolithophore. (The white bar just visible at the bottom left is 1 millionth of a metre long.) Chalk is formed of plates from its body.
