Definition of generative cell in English:
A reproductive cell, especially a cell of an angiosperm pollen grain that divides to produce two male gamete nuclei.
- In the embryo sac, the double fusion of the generative cells with the egg cell and the two nuclei of the central cell give rise to the diploid zygote and the triploid endosperm, respectively.
- Inspection of serially sectioned pollinated carpels indicates that approx. 89% of grains contain cytoplasm, a vegetative nucleus and nucleated generative cell.
- The generative cell in angiosperms is invariably spindle-shaped, except in orchids.
