¿Cuál fue la primera planta?

The video explores the evolution of plants, starting from early photosynthetic organisms to the diverse flora we see today. It highlights key events like the emergence of photosynthesis, the accumulation of oxygen, and the development of land plants. The video also discusses the impact of plants on climate and their role in shaping the Earth's environment. Through endosymbiosis, eukaryotic cells integrated bacteria, leading to the formation of mitochondria and chloroplasts, crucial for plant evolution. The narrative is supported by fossil records and scientific evidence, illustrating the profound influence of plants on life and the planet.
