Tag: importance of pollination

Anemophilous flowers have certain characters like:-

The pollen grains which are very light in weight can be passed on by wind from one flower to another or to the stigma of the same flower. This is known as wind pollination. They produce light weight pollens in large number and do not produce vector. The stigma is sticky.

Yucca is the pollinated by a moth known as the Tegeticulla yuccasella.  Each spring, adult moths emerge from the underground cocoons. And the males and females meet up with each other on Yucca plants for mating.

The Yucca moth is also termed as the pronuba moth. It is a small white moth that lives in the semi-arid habitats where Yucca plants grow.

Thus the correct answer is A.

Bat-pollinated flowers tend to be large and showy, white or light coloured, open at night and have strong musty odours. They are often large and bell-shaped or a ball of stamens. Flowers are typically borne away from the trunk or other obstructions. More than 500 species of plants, spanning 67 plant families, are pollinated by bats. This pollination syndrome is known as chiropterophily. In general, flowers that use this approach tend to be white or dull in colour, open at night, rich with nectar, and musty or rotten smell. 

Even in absence of pollinating agents, seed setting is assured in Commelina, which is also called as 'Asiatic dayflower'. They lack nectar, they offer only pollen as a reward to their visitors. To attract pollinators, the plant has three types of brightly coloured floral organs: the large blue petals, fertile yellow anthers and infertile yellow antherodes that lack pollen.
