Germination | series of events that results in the growth of a plant from a seed |
Pistil | female reproductive organ inside the flower of an angiosperm; consists of a sticky stigma, where pollen grains land, and an ovary |

Sporophyte Stage | plant life cycle stage that begins when an egg is fertilized by a sperm |
