A seed is an embryo of a plant encased in a protectivecovering and surrounded by a food supply.

Seeds
•Includes flowersAnd gymnosperms
•Do not need water
• Can live anywhere
•Protected by a seed coat
• Provides a food sourcefor the embryo.
• Can disperse in different ways.
Spores
•Includes mosses and ferns.
• Need water for reproduction.•Must live near water
•No protection from harsh conditions.
•New plant must make its own food.
• Must grow where it lands.

How can seeds be dispersed?
Animals – ingestingand excreting the seeds.

Seed plants are organized into 2 categories:
•Cone-bearing plants(Gymnosperms)
•Flowering plants(Angiosperms)
•Seeds are found on the surface of the cones,not included in a fruit
•Seeds are enclosed in some type of a fruit
•Seed bearing structuresare woody cones.
• Seed bearing structuresare fruit
•Seed plants do not need water to reproduce,the transfer of sperm is by pollen. Embryos are protected in the seeds.
