pollination | transfer of pollen grains to the female part of a seed plant by agents such as gravity, water, wind, and animals |

rhizome | underground stem |
frond | leaf of a fern that grows from the rhizome |
sporophyte stage | plant life cycle stage that begins when an egg is fertilized by a sperm |
gametophyte stage | plant life cycle stage that begins when cells in reproductive organs undergo meiosis and produce haploid cells (spores) |
spore | waterproof reproductive cell of a fungus that can grow into a new organism; in plants, haploid cells produced in the gametophyte stage |
