An illustration of the aboral side view of the Noctiluca scintillans. Noctiluca scintillans, also published as Noctiluca miliaris, is a free-living non-parasitic marine-dwelling species of dinoflagellate that exhibits bioluminescence. The bioluminescent characteristic of N. scintillans is produced by a luciferin-luciferase system located in thousands of spherically shaped organelles, or "microsources", located throughout the cytoplasm of this single-celled protist. Nonluminescent populations within the genus Noctiluca lack these microsources.

St Mark's Campanile is the bell tower of St Mark's Basilica in Venice, Italy, located in the square (piazza) of the same name. It is a recognizable symbol of the city. The tower is 98.6 meters tall, and stands alone in a corner of St Mark's Square, near the front of the basilica. It has a simple form, the bulk of which is a plain brick shaft, 12 meters on a side and 50 meters tall, above which is the arched belfry, housing five bells. The belfry is topped by a cube, alternate faces of which show walking lions and the female representation of Venice (la Giustizia: Justice). The tower is capped by a pyramidal spire, at the top of which sits a golden weathervane in the form of the archangel Gabriel. The campanile reached its present form in 1514. As it stands today, however, the tower is a reconstruction, completed in 1912 after the collapse of 1902.

An longitudinal section view of a disk-floret of the senecio flower. Senecio is a genus of the daisy family (Asteraceae) that includes ragworts and groundsels. The flower heads are normally rayed, completely yellow, and the heads are borne in branched clusters. Though of late the genus has been reviewed and split up, it still contains a vast number of species (about 1,500) of extremely wide form including leaf succulents, stem and tuber succulents, annuals, perennials, aquatic forms, climbers, shrubs and small trees. Some species produce natural pesticides (especially alkaloids) to deter or even kill animals that would eat them.
