How these systems allowed plants to grow taller and transport nutrients and water efficiently.
Seeds and Survival (02:30 - 03:15)
The transition from spore-based reproduction to seed production.
The advantages of seeds as protective habitats with built-in food supplies for embryos.
The Rise of Flowers (03:15 - 04:00)
