spores | waterproof reproductive cells 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 structures or an entire new plant or can develop into sex cells. |
gametophyte stage | plant life cycle stge that begins when cells in reproductive organs undergo meiosis and produce haploidcells (spores) |
sporophyte stage | plant life cycle stge 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. |
prothallus | small, green, heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil. |
pollen grain | small structure produced by the male reproductive organs of a seed plant; has a water-resistant coat, can develop from a spore, and contains gametophyte parts that will produce sperm. |
pollination | the transfer of pollen grains to the female part of a seed plant by agents such as gravity,water,wind,and animals. |
ovule | in seed plants, the female reproductive part that produces eggs. |
stamen | male reproductive organ inside the flower of an angiosperm; consists of an anther, where pollen grains form, and filament. |
pistil | female reproductive organ inside the flower of an angiosperm; consists of a sticky stigma, where pollen grains land, and an ovary. |
ovary | swollen base of an angiosperm's pistil, where egg producing ovules are found. |
germination | series of events that results in the growth of a plant froma seed. |
