| the joining of two haploid cells begins this stage | sporophyte |
| when and egg and sperm combine | fertilization |
| depending on the species of plant, these organs can be on the same or different plants | reproductive |

| in seed plants, some spores develop into small structures called: | pollen grains |
| the transfer of pollen grains to hte female part of the plant is called: | pollnation |
| The egg is produced in the: | ovule |
| is the male rproductive organ | stamen |
