Question

Anemophilous pollination is mainly observed in
a) Gramineae
b) Annonaceae
c) Papilionaceae
d) Euphorbiaceae

Answer 1

Hint: Pollination is the process of pollen grains being transferred from a flower's male anther to its female stigma. Pollen can be transferred between flowers of the same species to produce seeds.

Complete answer:
Anemophily, also known as wind pollination, is a form of pollination in which pollen is carried by the wind. Many plants in the order Poales, such as grasses, sedges, and rushes, are anemophilous, as are almost all gymnosperms. Oaks, pecans, pistachios, sweet chestnuts, alders, and members of the Juglandaceae family are among the most common anemophilous plants. The stamens of these flowers are long and protrude from the flower to aid pollination by the wind. The pollens are very light and dry, and the anthers are loosely bound to the filament. The stigmas of the flower are feathery and protrude from the flower. The Gramineae family of monocotyledonous flowering plants known as grasses and is a large and nearly ubiquitous monocotyledonous flowering plant family. Cereal grasses, bamboos, native grassland grasses, grasses grown in lawns and pastures are all included in Gramineae. Maize is an example of Gramineae that are subjected to wind pollination. The anthers of maize flowers are loosely attached to the filaments and can be blown away by the slightest breeze. Pollen is quickly blown away as a result of this. Due to its wide surface area, pollen grains can easily land on the feathery stigma emerging from the petals of another female flower. Since male flowers mature before female flowers, self-pollination is impossible.

Hence, the correct answer is option a) Gramineae.

Note:
A lack of fragrance, a lack of flashy floral parts resulting in tiny, inconspicuous flowers, decreased nectar production, and the production of enormous amounts of pollen grains are all characteristics of the wind-pollination syndrome.
