Seed Plants

Seed Plants. Gymnosperms & Angiosperms. What is a seed?. A seed contains an embryonic sporophyte Has a protective coat and enough nutrients to support the sporophyte until it is ready to germinate Seeds differ depending on their mode of species dispersal… eg . wind, animals, water etc.
