Heliotropism (Botany π±)
Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts 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". The Greeks assumed it to be a passive effect, pr...

Sunflowers are famous for their ability to track the sun throughout the day and then reorient at night to face east the following morning. This study uses gene expression and light manipulation approaches to reveal that sunflowers use multiple photoreceptors and distinct growth pathways to generate daytime and nighttime bending movements during heliotropism.

Fun fact: Sunflowers are known for their ability to turn their faces towards the sun, a behavior called heliotropism. As the sun moves across the sky during the day, young sunflowers will follow it, tracking its movement with their heads. However, as sunflowers mature and their stems become stiffer.
