Algal cell and diatom. Light microscope footage of a large rod-shaped green algal cell, and a diatom (top right). Algae are usually aquatic and photosynthetic. Diatoms are single-celled algae that form an important part of the plankton at the base of the marine and freshwater food chains. They are characterised by their silica cell wall, called a frustule, which typically consists of two symmetrical halves.
