2. Alternation of Generations All plants have a life cycle in which a diploid sporophyte generation alternates with a haploid gametophyte generation.

3. Moss have a dominant gametophyte Non-vascular

4. Ferns have a dominant sporophyte Vascular

5. Gymnosperm Lifecycle Vascular Wind pollinated!

19. Plant Propagation & Agriculture  Vegetative reproduction includes the production of new plants from horizontal stems, cuttings, leaves, plantlets, and underground roots.  Horticulturists use plant propagation to make many identical copies of a plant or to produce offspring from seedless plants.  Most of the people of the world depend on a few crop plants, such as wheat, rice, and corn, for the bulk of their food supply.
