Do Sunflowers Move At Night. Scientists have answered a burning question central to the charm of sunflowers: During this time, the flowers droop and the petals bend downwards. the fact that sunflowers switch directions at night to face east again, with no apparent cue, suggested an internal clock at work. sunflowers not only pivot to face the sun as it moves across the sky during the day, but they also rotate 180 degrees during the night to greet the morning sun. Instead, they go into a state of rest called nyctinasty. This is a defense mechanism to protect their pollen from the cold night air. Additionally, it is thought that this behavior helps the sunflowers conserve energy since photosynthesis does not occur at night. during the night, the shoots reorient their apices to face east again at sunrise (see the figure). Uc davis and uc berkeley researchers have now discovered how they do it: “the plant anticipates the timing and the direction of dawn, and to me that looks like a reason to have a connection between the clock and the growth pathway,” harmer said. They’ve linked their internal clock genes to stem growth, so that the eastern side of the stem elongates more. at night, sunflowers typically close up their petals and turn their heads towards the west. How do they do it?. This helps protect the flowers from cold temperatures and potential damage from nocturnal animals. growing sunflowers begin the day with their heads facing east, swing west through the day, and turn back to the east at night.
