Are we not lucky that plants reproduce sexually? The
myriads of flowers that we enjoy gazing at, the scents and
the perfumes that we swoon over, the rich colours that
attract us, are all there as an aid to sexual reproduction.
Flowers do not exist only for us to be used for our own
selfishness. All flowering plants show sexual reproduction.
A look at the diversity of structures of the inflorescences,
flowers and floral parts, shows an amazing range of
adaptations to ensure formation of the end products of
sexual reproduction, the fruits and seeds. In this chapter,
let us understand the morphology, structure and the
processes of sexual reproduction in flowering plants
(angiosperms).

happiness, grief, mourning, etc. List at least five flowers
of ornamental value that are commonly cultivated at
