Question

Which type of floral reward is provided by amorphophallus to its pollinators?

Answer 1

Hi there!

Floral reward is any part of the flower which attracts the pollinating agents like insects, birds, etc and ensures that they visit the flowers regularly which will increase the chances of pollination.


Thanks!✔️

Answer 2

Transfer of pollen grains to the stigma of a pistil is called pollination. Depending on the source of pollen, there are three types of pollination, viz, autogamy, geitonogamy and xenogamy.

Autogamy: When pollen grains from the anther are transferred to the stigma of the same flower, pollination is called autogamy.

Chasmogamous Flower: When a flower exposes its anthers and stigma, the flower is open to pollination from any other flower. This condition is called chasmogamy and such a flower is called chasmogamous flower. Complete autogamy is rare in chasmogamous flower. Perfect synchronization between pollen release and stigma receptivity is required in such flowers to allow self-pollination.

Cleistogamous Flower: When a flower does not open at all and thus does not expose its anthers and stigma, it is called cleistogamous flower. Self-pollination or autogamy is guaranteed in such condition. Examples: peanut, pea, beans, viola, etc. Cleistogamy ensures seed set even in the absence of pollinators. But cliestogamy is not advantageous as it promotes in-breeding depression in the population.
