Pollen Grain
Underground stem of a fern
Rhizome

Transfer of pollen grains to the female part of a seed plant by agents such as gravity, water, wind, and animals
pollination
female reproductive organ that produces eggs and is located in the lower part of the body
ovary
plant life cycle stage that begins when cells in reproductive organs undergo meiosis and produce haploid cells (spores)
