Bryophytes were the dominant plants in the first 100 million years of plant evolution. By the Carboniferous period, seedless vascular plants formed giant forests. Why were these plants able to outcompete bryophytes?
a. Their vascular tissue allowed them to grow tall, competing for light and more widely dispersing their spores. b. Their protected embryos were better able to withstand dry conditions, providing a selective advantage in dominating terrestrial habitats. c. They did not require water for their sperm to swim to fertilize the eggs, allowing them to colonize dry habitats. d. They were diploid, so they could grow faster and taller than haploid bryophytes. e. They had megaspores and microspores. This extra genetic variation enabled natural selection to favor taller growth.
