Seeds

Definition  A propagation organ formed in the sexual reproduction cycle of gymnosperms and angiosperms  Consists of:  Protective coat enclosing-  Embryo  Food reserves

Dispersal Mechanisms  Animal  Water  Wind nce/plants_pt2/dispersal.htm

Parts of a Seed

 Seed coat: protective covering  Hilum: A scar on the seed coat indicates the place where the seed was attached to the fruit or ovary of its parent plant  Micropyle: tiny opening in the seed coat where pollen entered the seed and caused it to mature
