Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically . Natural patterns include symmetries , trees , spirals , meanders , waves , foams , tessellations , cracks and stripes. [ 1 ]
Satyrium carneum.Ground orchid with typical zygomorphic floral anatomy. Zygomorphic ("yoke shaped", "bilateral" – from the Greek ζυγόν, zygon, yoke, and μορφή, morphe, shape) flowers can be divided by only a single plane into two mirror-image halves, much like a yoke or a person's face.
ABC model of flower development guided by three groups of homeotic genes. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
This pattern of development (with a distinct head and tail) is called cephalization. It is also argued that the development of an AP axis is important in locomotion – bilateral symmetry gives the body an intrinsic direction and allows streamlining to reduce drag. In addition to animals, the flowers of some plants also show bilateral symmetry.
The morphology of most flowers (called cyclic flowers) is based on four types of whorls: The calyx: zero or more whorls of sepals at the base; The corolla: zero or more whorls of petals above the calyx; The androecium: zero or more whorls of stamens, each comprising a filament and an anther
Flowers have specifically adapted to consistently target a particular pollinator as their hue or intensity of coloration is in the peak wavelength for their pollinator to see and be attracted to. [5] A flower’s size, shape, color, scent, and pattern all play a role in signaling with the senses of pollinators. [2]

Possibly as a result of this unique property, the spira mirabilis has evolved in nature, appearing in certain growing forms such as nautilus shells and sunflower heads. Jacob Bernoulli wanted such a spiral engraved on his headstone along with the phrase " Eadem mutata resurgo " ("Although changed, I shall arise the same."), but, by error, an ...
