The Word Itself Comes From The Greek Phullon, Meaning Leaf, And Taxis, Meaning Arrangement. Phyllotaxis, In The Restricted Sense, Is The Study Of The Relative Arrangement Of What Is Called The Primordia Of Plants.
(c) individual spirals making up a spiral pattern are called parastichies. Two key questions in biology are to understand how biological patterns emerge and what their physiological functions are. In general, the range of values of α 0 and l that result in a given fraction α is obtained as delineated in supplementary fig. 1, 2, 3, 5, 8, 13, 21, 34, 55, 89., where every number in the sequence appears as a sum of two preceding numbers, is of great importance in phyllotaxis.

Numerous reviews have dealt with the molecular genetic mechanisms underlying phyllotaxis, and. The presence of fibonacci numbers (and other recurve series) is a consequence of the recursive process of morphogenesis of spiral patterns of phyllotaxis. The pine cone shown has parastichy numbers 8 and 13, the sunflower has 34 and 55. Both models relate phyllotaxis to packing problems.
