Prothallus | Small, green, heart-shaped gametophyte plant form of a fern that can make its own food and absord water and nutrients from the soil |
Gametophyte Stage | Plant life cycle stage that begins when cells in repoductive organs undergo meiosis and produce haploid cells |
Spore | In plants, haploid cells produced in the gametophyte stage that can divide by mitosis to form plant structures or an entire new plant |
Sporophyte Stage | Plnat life cycle stage that begins when an egg is fertilized by a sperm |
Frond | Leaf of a fern that grows from the rhizome |
Rhizome | Underground stem |
Sori | Fern structures in which spores are produced |
Pollen Grain | Small structure produced by the male reproductive organs of a seed plant; has a water-resistent coat, can develop from a spore, and contains gametophyte parts that will produce sperm |
Pollination | Transfer of pollen grains to the female part of a seed plant by agents such as gravity, wind, water, and animals |
Ovule | In seed plants, the female reproductive part that produces eggs |
Stamen | Male reproductive organ inside the flower of the angiosperm; consists of an anther where pollen grains form, and a filament |
Pistil | Female reproductive organ inside the flower of an angiosperm; constist of a sticky stigma; where pollen grains land, and ovary |
Ovary | Swollen base of an angiosperms's pistil, where egg-producing ovules are found |
Germination | Series of events that results in the growth of a plant from a seed |
