GYMNOSPERMS:
-Introduction – Gymnosperm means “naked seed” (From the Greek: gymnos = naked; sperm = seed)
-More advanced than ferns – do not have spores, they have seeds.
-The seeds of the gymnosperms lack a protective enclosure (unlike flowering plants which have flowers and fruit).
-Examples of gymnosperms:
Conifers (pine trees), cycads, ginkgo biloba

Gymnosperm life cycle:
-Exhibits alternation of generations
-Sporophyte generation (2n) is dominant
-Gametophyte generation (1n) is contained in and dependent on the sporophyte generation
