The basic function of the petal is to attract insects and mammals to the flower for pollination; to a certain degree they also offer a small amount of protection to the reproductive structures. Some petals play a secondary roll providing a landing platform for pollinators (mainly insects).

The petals are also called the inflorescence of the the flower.

In Dicotyledonous flowers the petals are protected when young by the calyx.

In Dicotyledonous plants the flowers either have petals in multiples of 4 or 5 (eg. 4, 8, 12 or 5, 10, 15 etc.).

In Monocotyledonous plants the flower have petals in multiples of 3 (eg. 3, 6, 9 etc.).

Some petals are brightly coloured and are pleasant for humans to look at.

Flowers that sometimes appear drab to humans are patterned in ways that are visible to animals and insects, but not us - they may contain pigments and patterns that are only visible in utraviolet light (which some insects can see).

Petals have no function in photosynthesis.
