germination | series of events that results in the growth of a plant form a seed |
stamen | male reproductive organ inside the flower of an angiosperm; consists of anther, where pollen grains form, and a filament |
spore | in plants, haploid cells produced in the gametophyte stage that can divide by mitosis to form plant structures or on an entire new plant or can develop into sex cells |
gametophyte stage | plant life cycle stage that begins when cells in reproductive organs undergo meiosis and prodce haploid cells |
sporophyte stage | plant like cycle stage that begins when an egg is fertilized by a sperm |
sori | fern structures in which spores are produced |
frond | leaf of a fern that grows from a rhyzome |
rhyzome | underground stem |
prothallus | small green heart shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients |
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 produce sperm |
pistil | female reproductive organ inside the flower of an angiosperm; consists of sticky stigma, where pollen grains land, and an ovary |
pollination | transfer of pollen grains to the female part of a seed plant by agent such as gravity, water, wind, and animals |
ovule | in seed plants, the female reproductive part that produces eggs |
ovary | swollen base of angiosperm's pistil, where egg-producing ovules are found. |
