Question

Pollination in Pinus is
A)Entomophilous
B)Anemophilous
C)Hydrophilous
D)Zoophilous

Answer 1

Hint: The mechanism of pollination occurs as pollen grains are moved from the male portion of one flower to the female portion (stigma) of another flower. The fertilized flowers produce seeds after pollination occurs, helping the related plant to replicate and/or form fruit.

Complete answer:
Entomophilous or insect pollination is a method of pollination by which insects disperse pollen from plants, especially but not only from flowering plants. The use of water as a vector in the movement of pollen is part of hydrophilous pollination. The pollen itself does not need to come into contact with water as water-borne conveyances such as anthers or flowers can transport dry pollen over the surface of the water. Zoophilia is a type of pollination in which animals, usually invertebrates, but in some cases vertebrates, in particular birds and bats, but also other animals, spread pollen.

The anemophilous plants include the Pinus flower, which produces a large amount of wind-carrying pollen. Other common anemophilous plants include oaks, sweet chestnuts, alders, and members of the Juglandaceae family (hickory or walnut family).

Hence, the correct answer is option (B)

Note: A loss of fragrance production, a lack of showy floral sections (resulting in tiny, inconspicuous flowers), decreased nectar development, and the production of large amounts of pollen grains are features of the wind-pollination syndrome. It differentiates them from entomophilous and zoophilous animals (whose pollen is spread by insects and vertebrates respectively).
