actually it is both way traffic. in the process of evolution the plants have lost motility. in primitive forms the gametes male and female both were motile. over a period of time the female gamete become nonmotile, and became stationary on the plant. male gamete too lost its motility power and became dependent on some agent for carrying itself to other plant/ flower. The agent could be wind ,water, insect, bird, mammal, including human( (hybridization). for this the gamete had to modify itself. in addition the flowers had to adapt in such a way that these agens can facilitate the carring of gamete. They evolved to have colour, fragrance , different shapes, hights of filaments for anthers,etc etc. including modifications of gynoecium, androecium, corolla calyx and so on. Along with gametes even seed dispersal was also one of the very important aspect for which agents are required. on the other hand animals were dependent on plants for food- may be in the form of necter, pollen, leaves, flowers, fruits, etc etc. to get the food like foliage giraffee increased length of neck, while sunbird elongated its beak, butterfly became light waighted, birds developed their beaks, mammals their forelimbs and so on. so it is interdependancy one attract the other and get attracted to other madhuri
