To a biologist, flowers are morphological and embryological marvels and the sites of sexual reproduction. Much before the actual flower is seen on a plant, the decision that the plant is going to flower has taken place. Several hormonal and structural changes are initiated which lead to the differentiation and further development of the floral primordium.
