The photo above shows a small seed with miniature spikes around it. Plants try to disperse their offspring as far from the parent plant as they can, but because they are immobile, so they have adapted ways of dispersing their offspring. Some plants have adapted to use the wind, others like the one in the picture, use animals. The small spikes that surround the seed allow it to attach to the fur of animals. Eventually, the animal shakes off the seed, but not before giving it a free ride away from the parent tree. Seed dispersal is how plants are able to spread of large areas even though they are not mobile.
