Pistil | Female reproductive organ inside the flower of an angiosperm; consists of a sticky stigma, where pollen grains land, and an ovary. |
Stamen | Male reproductive organ inside the flower of an angiosperm; consists of an anther, where pollen grain form, and a filament. |
Ovule | In seed plants, the female reproductive part that produces eggs. |
Pollination | Transfer of pollen grain to the female part of a seed plant by agents such as gravity, water, wind, and animals. |
Pollen Grain | Small structure produced by the male reproductive organ of a seed plant; has a water resistant coat can develop from a spore, and contains gametophyte parts that will produce sperm. |
Prothallus | Small, green, heartshaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil. |
Rhizome | Underground stem. |
Gametophyte Stage | Plant life cycle stage that begins when cells in reproductive organs undergo meiosis and produce haploid cells (spores). |
Spore | Hapoid cells produced in the gametophyte stage that can divide by mitosis to form plant structures or an entire new plant or can develop into sex cells. |
Frond | Leaf or a fern that grows from the rhizome. |
Sori | Fern structures in which spores are produced. |
Sporophyte Stage | Plant life cycle stage that begins when an egg is fertilized by a sperm. |
