Question

Cleistogamy is leading over anthesis because
a) Pollination agents are not required.
b) It assures heterozygosity.
c) It favours insect pollination.
d) It allows xenogamy.

Answer 1

Pollination is a component of sexual propagation in flowering plants and plays an important role in a flowering plant's life cycle. The term 'anthesis' refers to the time period during which the blossom bud remains completely open and becomes practical.

Complete answer:
The flowers of the cleistogamous species do not open at all. In such flowers, the anthers and stigma are close together. Pollen grains associate with the stigma as anthers dehisce in flower buds, affecting fertilisation. Since cross-pollination is unlikely, cleistogamous flowers are autogamous. In these flowers, this reduces the need for a fertilisation specialist.
Cleistogamy is a type of specific self-fertilization of plants. This lead is particularly effective in peanuts, peas, and pansies, but it is generally widespread in the grass family. In any case, Viola is the most numerous cleistogamous plant group.
Anthesis is a period when the flower is open and, as a result, more useful. It is also referred to as the start of that particular period. So, in some species, this anthesis is fantastic. For example, in the species Banksia, anthesis includes the spread of style far beyond the perianth.

Hence, the correct answer is option A-Pollination agent is not required.

Note:
Cleistogamous flowers are those that consistently close flowers. Cleistogamy is the process of fertilisation that occurs in closed flowers. It's a condition in which the flower does not open. It is a plant variety that promises self-fertilization. The anthers and disgrace are almost touching in such flowers. Pollen grains interact with stigma to affect fertilisation precisely when another dehiscence in the flower buds. It ensures seed advancement even when no fertilisation trained professional is present. Arachis hypogaea have cleistogamous flowers.
