During the night, the flowers may assume a random orientation, while at dawn they turn again towards the East where the sun rises. The motion is performed by motor cells in a flexible segment just below the flower, called a pulvinus. The motor cells are specialized in pumping potassium ions into nearby tissues, changing their turgor pressure. The segment flexes because the motor cells at the shadow side elongate due to a turgor rise. Heliotropism is a response to blue light. Some solar tracking plants are not purely heliotropic: in those plants the change of orientation is an innate circadian motion triggered by light, which continues for one or more periods if the light cycle is interrupted. Leaf heliotropism is the solar tracking behavior of plant leaves. Some plant species have leaves that orient themselves perpendicularly to the sun's rays in the morning (diaheliotropism), and others have those that orient themselves parallel to these rays at midday (paraheliotropism). Floral heliotropism is not necessarily exhibited by the same plants that exhibit leaf heliotropism. The research by MIT Scientists to adopt the peculiar nature of some plants to tracking system of Solar panels is indeed a major breakthrough.

Much of energy produced by solar is last in providing power to the tracking system. The wonderful research by MIT students (Forrest Liau, Vyom Sharma, and George Whitfield) will help to solve the problem by adopting the motion of SUNFLOWER. Many plants are phototropic/heliotropic, gradually tilting towards the sun to optimize solar energy capture. Practically, the heliotropic solar panel could be useful in developing areas, where motor-based sun-tracking panels are not affordable. From an expressive standpoint, a solar panel that tilts towards the sun (like a sunflower) can help the public see a connection between the natural and the high tech. I heartily congratulate the MIT Students for their wide vision of adopting from nature to solve a complex problem in a simple way.
