Pollination that occurs through agency of an insect is called Entomophily. Entomophilous flowers are usually brightly coloured and scented and often secrete nectar. Hence attractants and rewards are required for insects inorder to carry out pollination.

Statement A : Pollination by water is more common amongst abiotic pollinations. Statement B : Pollination by wind is quite rare in flowering plants and is limited to about 30 genera, mostly monocotyledons.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.

A moth species_________ and the plant _______cannot complete their life cycles without each other.
1 Pronuba yuccasella, Amorphophallus
2 Pronuba yuccasella, Yucca
3 Pronuba yuccasella, Vallisneria
4 Pronuba yuccasella, Zostera
Explanation:
A similar relationship exists between a species of moth (Pronuba) and the plant Yucca where both species – moth and the plant – cannot complete their life cycles without each other. The moth deposits its eggs in the locule of the ovary and the flower, in turn, gets pollinated by the moth. The larvae of the moth come out of the eggs as the seeds start developing.

The term used for transfer of pollen grains from anthers of one plant to stigma of a different plant which, during pollination, brings genetically different types of pollen grains to stigma, is :
1 Xenogamy
2 Geitonogamy
3 Chasmogamy
4 Cleistogamy
Explanation:
Xenogamy is a cross pollination in which pollen grain from anther of one flower to the stigma of another flower are transferred in order to get fertilized.
Pollination that occurs through agency of an insect is called Entomophily. Entomophilous flowers are usually brightly coloured and scented and often secrete nectar. Hence attractants and rewards are required for insects inorder to carry out pollination.
