Content: Life  cycle of plants. Plants  alternate between a haploid phase (the gametophyte)  and a diploid phase (the sprorophyte). The  gametophyte is dominant in the simpler non-vascular  plants. The  sporophyte is dominant in higher plants. ( see figure  19.2). Evolutionary  trends in plants. 1. The haploid phase is dominant in simpler plants; the  diploid phase is dominant in higher plants. 2.
