Question

Yucca is pollinated by
A) Pronuba Moth
B) Bumble Bee
C) Honey Bee
D) Butterfly

Answer 1

Hint: Pollination is referred to as the process of transfer of the pollen grains from the male part of a flower to the female part of the same or different flower. Reproduction of certain species of plant is influenced solely and only on pollination. Pollination can occur by wind, water or animals.

Complete answer:
Yucca is the member of family Asparagaceae. It is a kind of perennial shrub native to parts of America and the Caribbean. The plant shows the presence of small white flowers. The morphology of the Yucca flowers is found in a way that it does not support self-pollination. The stamens and the pistil are curved in distance from each. The stamen produces gelatinous pollen grains that cannot be easily detached from the stamen, making it impossible to be pollinated by wind. Also, the stigma is developed in such a way that the pollen has to be inserted into it, rather than falling on the filament to reach the ovary.

Now let us find solution from given options:
A) Pronuba Moth: These species are pollinated and are fertilised by Yucca moths that are the members of genus Pronuba. These two species share a common relationship termed as obligate mutualism in biological terms, that is one species is completely dependent on the other for survival.
B) Bumble Bee: These are more good pollinators than honey bees. They are used to pollinate the greenhouse grown tomatoes.
Honey Bee: These are good pollinators and they are used to pollinate the flowering plants.
Butterfly: They are also used to pollinate plants and they obtain nectar

Hence, the correct answer is option (A).

Note: The Yucca flower and Pronuba moths are known to connect through obligate mutualistic relationships. These two species are connected to each other for their survival. This is because the Yucca larvae eat Yucca seeds, while the Yucca flowers are solely dependent on the Pronuba moths for pollination.
