cholla cactus
What is special about the way this plant reproduces?

Answer:

In addition to producing flowers and seeds, the cholla cactus also reproduces by breaking apart. When an animal (or Happy Scientist) bumps into the cactus, the thorns stick firmly in your skin. A gentle tug causes that part of the cactus to break free. When you finally manage to carefully pry it off your skin, you usually throw the broken piece to the ground, where it happily grows into a new cactus.
