The placentation type present in lady's finger (Okra) is: Correct Answer Axile

Concept-

  • A typical flower has four main parts - or whorls - known as the calyx, corolla, androecium, and gynoecium.
  • The innermost group of structures in the flower is the gynoecium, or the female reproductive component(s).
  • The innermost whorl is the whorl of the carpel and is called gynoecium.
  • The carpel is the individual unit of the gynoecium and has a stigma, style, and ovary.
  • The ovary is the enlarged basal part.
  • The arrangement of ovules within the ovary is known as placentation.
  • The placentation is of different types namely, marginal, axile, parietal, basal, central, and free central.

Additional Information

Free Central

  • When the ovules are borne on a central axis and septa are absent, as in Dianthus and Primrose the placentation is called free central.

Parietal

  • In parietal placentation, the ovules develop on the inner wall of the ovary or on the peripheral part.
  • The ovary is one-chambered but it becomes two-chambered due to the formation of the false septum, e.g., mustard and Argemone
