Detailed explanation-1: -Four major adaptations are found in all terrestrial plants: the alternation of generations, a sporangium in which the spores are formed, a gametangium that produces haploid cells, and apical meristem tissue in roots and shoots.
Detailed explanation-2: -Plants may have colonized the land as early as 700 million years ago. The oldest fossils of land plants date back about 47 0 milli on years. The first land plants probably resembled modern plants called liverworts, like the one shown in Figure below.
