plants are very adaptable, depending on the clade. some can only sprout if their seeds are damaged fires, or if they have a period of dormancy. genetically, polyploidy has given plants significant advantages as well, having multiple copies(more than 2, in series of 2s and odd numbers) allow some alleles to evolve without causing detrimental effects. plus mycoheterotrophic plants started to evolve(just before or around this time, in many lineages to take advantage of fungal symbionts and low light, the tradeoff is they are rare for the most part.
