About Lesson
Gynoecium (Pistil):-
- It represents the female reproductive part of the flower.
- It may consist of a single pistil (monocarpellary) or more than one pistil (multicarpellary).
- When there are more than one, the pistils may be fused together (syncarpous) or may be free (apocarpous).
Each pistil has three parts:
- 1. Stigma: It is a landing platform for pollen grains.
- 2. Style: It is an elongated, slender part beneath the stigma.
- 3. Ovary: It is the basal bulged part of the pistil.
- Inside the ovary is the ovarian cavity (locule) in which the placenta is located.
- Arising from the placenta are the ovules (megasporangia).
- The number of ovules in an ovary may be one (wheat, paddy, mango, etc) to many (papaya, watermelon, orchids, etc.).
