Next came the rebels. They developed vessels (vascular tissue) to transport water high into the sky. During the Carboniferous period, they grew as tall as skyscrapers, creating the world's first true forests.

Once upon a time in a quiet biology classroom, a 7th-grade student named Mark sat staring at a blank screen. His cursor blinked like a heartbeat, mocking him. He had one task: write a report on . As Mark wrote, he imagined the different groups

Mark started his story with a mystery. Long ago, all plants lived in the ocean. They were simple algae, swaying in the tides. But then, some brave ancestors decided to leave the water and step onto the dry, harsh land.
