flower
Definition
- [Henderson's] n. the reproductive structure of angiosperms (Anthophyta q.v.), being derived evolutionarily from a leafy shoot in which leaves have become modified into petals, sepals and calyx, and into the carpels and stamens in which the gametes are formed. Although flowers can take many different forms, they can all be represented by concentric whorls of different parts inserted on a base (the receptacle). The outermost whorl of sepals (often green) forms the calyx, inside that is a whorl of often brightly coloured petals, next is a ring of stamens (the male reproductive organs), and in the centre are the carpels (the female reproductive organs). see Fig. 18.
