surface of water and mud. Algae were evolving at the water’s edge‚ and one group – probably the charophytes – gave rise to plants. Cooksonia‚ a simple branching plant a few centimeters tall‚ evolved by 430 million years ago. It took another 160 million years for the taller Psilophyton to evolve. Then the evolutionary pace picked up. It took only 60 million years for plants radiate from the swampy lowlands to high mountains and nearly all places in between. They did so through modifications in

A world without plants Plants; probably the most ignored organism on this planet. People walk past plant and cut them down but nobody ever thinks about what they do for us‚ what the world would be if there was never any plants or photosynthetic organisms. If the world never had these organisms the world would be a desolate place. There would be no oxygen‚ atmosphere‚ or food. We inhale air unconsciously every day. By taking in air‚ we absorb oxygen and discharge carbon dioxide in the process of
