Everywhere in the plant world there are patterns, and these patterns often organize themselves around symmetry. When a figure “mirrors” itself in an even proportion, we say that the object has symmetry. The flower in the picture above is symmetrical, and specifically has rotational symmetry. You can turn the flower in any direction and the image looks exactly the same. Next time you are on a walk or in a garden, look around and explore the symmetry!
