| Question | Answer |
|---|---|
| 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 |
| 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 hapliod cells |
| pistil | female reproductive orgam inside the flower of an angiosperm |
| stamen | male reproductive orgam inside the flower of an angiospersm consists of an anther, where pollen grains form, and a filament |
| ovule | in seed plants, the female reproductive part, that produces eggs |
| germination | series of events that results in the growth of a plant from a seed |
| ovary | swollen base of an angiosperms pistil, where egg- producing ovules are found |
| spore | waterproof reproductive cell of a fungus that can grow into a new organism,in plants, hapliod cells produced in the gametophyte stage can divide by mitosis to form plant structures or an entire new plant can develope into sex cells |
| pollen grain | small structure produces by the male reproductive prgans of a seed plant; has a water resistant coat, can develop from a spore, and contain gametophyte parts that will produce sperm |
| prothallus | small green heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the siol |
| sori | fern structures in which spores are produced |
| frond | leaf of a fern that grows from the rhizome |
