| These probably had an isomorphic alternation of generations and were probably filamentous. |
| The alternation between haploid gametophyte and diploid sporophyte phases, known as alternation of generations, occurs in all multi-cellular plants. |
| The life cycle of pteridophytes exhibits an alternation of generations between gametophytes and sporophytes. |
| The alternation of generations illustrates an important principle, namely that cell lineages arising from single parental cells containing the same genetic potentiality may pursue mutually exclusive developmental patterns. |
| Like all land plants, they have a life cycle referred to as alternation of generations, characterized by alternating diploid sporophytic and haploid gametophytic phases. |
| At the same time there was the alternation of generations concerning the lead of the enterprise: Marius Haberthür and Fritz Kasper faced the new challenges vigorously with a clear entrepreneurial concept. |
