__**1-Describe one way pollen can be scattered.**__ hawraa: wind. Kawssar: through bees Alia Olivia: Wind.
 * * **When pollen reaches the center part of a flower, the flower forms seeds.*Wind and animals can pollinate flowers.*After a cone is pollinated, seeds form inside the cone.

__**2-How do plants with cones form seeds? **__ hawraa : Gymnosperms propagate through sexual reproduction. Wind-borne pollen grains from pollen cones land on ovulate cones, where they germinate, while a megaspore inside each ovule develops and divides to form female gametophytes. Eventually, the pollen produces sperm that fertilize eggs inside the female gametophytes. The fertilized egg develops into an embryo, while the ovule enclosing it develops into the seed.

__3-How do plants with flowers form seeds?__ **//hawraa: Flowers are the reproductive part of most plants. Flowers contain pollen and tiny eggs called ovules. After pollination of the flower and fertilization of the ovule, the ovule develops into a fruit. //** //kawssar: Flowers are the reproductive part of most plants.

Pollination and fertilization occur in the flower and the ovule when fertilized later develops to a seed.** References
