The plant kingdom consists of four major groups: the nonvascular plants, the seedless vascular plants, the gymnosperms and the angiosperms. The nonvascular plants, such as mosses and liverworts, are one of the simplest groups of the true plants.
Like all plants, nonvascular plants have an alternation of generations life cycle. In the life cycle of the nonvascular seedless plants, the gametophyte stage is the longest part of the cycle. The gametophyte is photosynthetic.The life cycle of nonvascular seedless plants can be described as follows: 1  The male gametophyte produces flagellated sperm that must swim to the egg formed by the female gametophyte. 2  For this reason, sexual reproduction must happen in the presence of water.ike all plants, nonvascular plants have an alternation of generations life cycle.
