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