The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period. Fossils indicate that plants were less severely affected by this and other mass extinctions. What adaptations may have enabled plants to withstand these disasters better than animals? Why are seed plants more successful than the so-called “lower plants”?

They are photoautotrophs. And they do not require oxygen. That is bigger than food source. They also require organic compounds to survive and those count as food.

Without light plants do require oxygen. But seeds, as the temperatures are low, remain resting in the earth until the circumstances improve. (In many cases for years and years) And so the species survives.
