The term anthesis refers to :

  • A.Formation of an anther
  • B.Opening of a flower
  • C.Development of flower
  • D.Dehiscence of anther

Answer: B

Anthesis is the opening of a flower.

Anthesis is the period when a flower is fully open and functional, with the anthers shedding pollen and the stigma receptive. The time of anthesis matters to plant breeders, who must emasculate or pollinate flowers at the right stage.

Formation of the anther and development of the flower happen before anthesis, and dehiscence of the anther is the splitting that releases pollen, which usually occurs at anthesis but is a separate term.
