Seed dispersal

Shows ways in which seeds of plants are scattered in order to insure propagation of the species: dispersal by wind, transportation by animals, and forceful propulsion from the seed case. Describes the anchoring methods of germination by clamping, hooking, adhesion, and corkscrew motion.

Considers various means by which seeds are disseminated; how they anchor themselves to the ground to facilitate germination; and how they protect themselves. Demonstrates the dispersal of seed plants by wind, transportation by animals, and propulsion from seed plants by wind, transportation by animals, and propulsion from seed cases. Describes anchoring methods by clamping, hooking, adhesion, and corkscrew motion. Portrays various natural devices for protection while sprouting.
