Question

Entomophilous flowers usually have: Dry pollen; Feathery stigma; or Conspicuous flowers

Answer 1

Answer:

ANSWER

Insect-pollinated flowers are large, conspicuous, bright coloured and have a pleasant smell. They have nectarines on receptacles or on spurs at the base of flower whorls and produce nectar to attract insects. Wind pollination does not require scented colourful flowers which makes option C incorrect. Wind-pollinated flowers have large, conspicuous, broad, well exposed and feathery stigma to catch windblown pollen. This makes option D correct. Sessile stigma has reduced style and stigma is directly seated on the ovary. Presence of sessile stigma will not expose it to wind to catch pollen. Option A is incorrect. A small and smooth stigma has less exposure to wind and less exposed surface area to catch pollen as well as its smooth nature does not grab the wind-blown pollen

Answer 2

The following are the characteristics of insect-pollinated flower:

1) pollen grains are sticky so that they can easily stick to the insect's body.

2) Flowers produce nectar to attract insects.

3) The large and colored petals are also to attract insects.

The stigma is a part where the pollen should reach in order to reproduce. Stigmas may be wet and dry. It is the place where the process of fertilization commences. Thus, the stigmas are not the characteristic of insect-pollinated flower.
