| 1. Anther development | PMC forms in microsporangia | PMC (2n) in anther | 2n |
| 2. Microsporogenesis | PMC → meiosis → microspore tetrad | 4 microspores (n each) | n |
| 3. Pollen grain maturation | Microspore → vegetative + generative cell | Mature 2-celled pollen grain | n |
| 4. Ovule development | MMC forms in ovule nucellus | MMC (2n) | 2n |
| 5. Megasporogenesis | MMC → meiosis → 4 megaspores | 3 degenerate; 1 functional megaspore | n |
| 6. Embryo sac formation | Functional megaspore → 3 mitotic divisions | 8 nuclei → 7 cells, 8 nuclei | n |
| 7. Pollination | Pollen transfers from anther to stigma | Pollen on stigma | n |
| 8. Pollen germination | Pollen tube grows through style | Pollen tube (intine) with tube nucleus + 2 sperm | n |
| 9. Fertilization (syngamy) | Sperm 1 + egg | Zygote | 2n |
| 10. Fertilization (triple fusion) | Sperm 2 + 2 polar nuclei | PEN | 3n |
| 11. Embryo development | Zygote → proembryo → globular → heart → torpedo | Embryo | 2n |
| 12. Endosperm development | PEN → repeated mitosis | Endosperm | 3n |
| 13. Seed formation | Embryo + endosperm + seed coat (from integuments) | Mature seed | Mixed |
| 14. Fruit formation | Ovary wall → pericarp | Fruit | 2n |
