Jul 31, 2022 · Learning Objectives. Identify the structures involved in reproduction of gymnosperms. The life cycle of a gymnosperm is characterized by alternation of generations. In conifers such as pines, the green leafy part of the plant is the sporophyte, and the cones contain the male and female gametophytes (Figure 1).
The two innovative structures of pollen and seed allowed seed plants to break their dependence on water for reproduction and development of the embryo, and to conquer dry land. The pollen grains carry the male gametes of the plant.
