Q. The bunchberry flower has the fastest-moving parts ever seen in a plant. Initially, the stamen are held by the petals in a bent position, storing elastic energy like a coiled spring. As the petals release, the tips of the stamen act like medieval catapults, flipping through a 60 angle in just 0.30 ms to launch pollen from the anther sacs at their ends. The human eye just sees a burst of pollen; careful photography reveals the details. we can model a stamen tip as a 1.0-mm-long, 10 rigid rod with a 10 anther sac at one end and a pivot point at the opposite end. Although oversimplifing, we will assume that the angular acceleration is constant throughout the motion.
