What is the function of flower?

The normal flower has three basic functions:

1. It provides a platform for the sexual reproductive system of the plant (androecium - male and gynoecium - female) - both monoecious and diecious flowers. Within the flower pollen and ovules are produced normally through the process of meiOSis.

Pollination takes place and ovules form into seeds, with the swollen ovary normally forming into a fruit (or seed pod). Flowers are a feature normally associated with angiOSperms, and cones characteristic of gymnosperms.

2. It provides a mechanism to attract pollinators to facilitate pollination (petals) - monoecious flowers and diecious flowers. Flowers provide a visual attractant to many pollinators (insects, birds, animals etc.), this is also sometimes in conjunction with a scented attractant such as nectar. These sensory "lures" attract insects which then transfer pollen between the flowers and facilitate pollination (either cross pollination or self pollination).

3. It provides a platform for fertilized ovules to develop and be distributed as fruit and seeds - monoecious flowers and female diecious flowers only.

Monoecious = having both sexes (male and female) on the same flower

Diecious = having separate sexed flowers (male flowers and female flowers)
