1A:Germination is the process by which an organism grows from a seed or similar structure.

2A:Flowering plants generate pollen, ovules, seeds, and fruit. Fertilization in flowering plants happens through a process called pollination. ... Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed.

3A:pollen grain is a minute body, of varying shape and structure, formed in the male structures of seed-bearing plants and transported by various means (wind, water, insects, etc.) to the female structures, where fertilization occurs. ... A pollen grain itself is not the male gamete.
