Seed plants developed several key adaptations that enabled them to thrive in drier environments, ultimately replacing spore-bearing plants. These adaptations include the formation of seeds, which provide a protective covering and a food supply for the developing embryo, allowing for greater survival in unfavorable conditions. Additionally, seed plants possess structures such as waxy cuticles and stomata that help minimize water loss, and they can reproduce without the need for water for sperm to swim to the egg, thanks to pollen. These features collectively enhanced their ability to colonize diverse terrestrial habitats.
