Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".

[14] Conversely, some flowers that are pollinated by moths or bats exhibit nyctinastic flower opening at night. [14]

[11] For example, the baobab is pollinated by fruit bats and starts blooming in late afternoon; the flowers are dead within twenty-four ...
Modern biologists believe [12] that it is the coincidence of the active forms of phytochrome or cryptochrome, created by light during the daytime, with the rhythms of the circadian clock that allows plants to measure the length of the night. Other than flowering, photoperiodism in plants includes the growth of stems or roots during certain ...
