NEET BIOLOGY

Detailed explanation-1: -C) Entomophily – it is insect pollination. Here pollen is carried by an insect. Insects are attracted by the attractants of plants and spores are distributed by them. So here attractants and rewards are required for pollination.

Detailed explanation-2: -Anaemophily is wind pollination and hydrophily is water pollination. Both wind and water are abiotic and hence do not need attractants and rewards.

Detailed explanation-3: -Attractants and rewards play vital roles in the pollination process. Attractant refers to flower colour and fragrance that attract insects such as bees, wasps, butterflies, etc. Plants provide rewards like nectar and pollen grains to facilitate insect pollination.

Detailed explanation-4: -Pollinators generally relies on plant attractant to guide them to the food resources as the rewards are often concealed within a flower, which cannot be seen directly by pollinators [94]. Animal-pollinated flower usually provide nectar to pollinators as a reward [95].

Detailed explanation-5: -The plants’ side of communication between flowers and pollinators includes the display or concealment of primary attractants, such as nectar, pollen or other kinds of floral rewards, and of secondary attractants of flowers and inflorescences to enable detection and discrimination by pollinators.
