NEET BIOLOGY

Detailed explanation-1: -This can happen through self-pollination, wind and water pollination, or through the work of vectors that move pollen within the flower and from bloom to bloom.

Detailed explanation-2: -Pollination by insects is called entomophily and pollination by birds is called ornithophily. Pollination by vertebrates is known as zoophily. Abiotic agents – Wind and water. Wind pollination is known as anemophily and pollination by water is called hydrophily.

Detailed explanation-3: -Answer: wind-pollinated plants may be allergens, but seldom are animal-pollinated plants allergenic. Their stigmas may be large and feathery to catch the pollen grains. Insects may visit them to collect pollen, but usually are ineffective pollinators and exert little natural selection on the flowers.

Detailed explanation-4: -In case pollination does not occur, the gametes will not fuse to produce zygote. As a result, fertilisation will not occur.
