It’s not an exaggeration to suggest that the most significant event on Earth was the evolution of photosynthesis. The ability to harvest energy from light freed life from the need to scavenge energy ...

Unlike us, plants don't need pantries full of food to stay alive; the Sun is their pantry. But, like us, they require fairly regular sustenance, which they create via photosynthesis. This seemingly ...

Plants and trees may seem pretty passive, but behind the scenes, their cells are working hard to put on a magic show. In this episode of Crash Course Botany, we’ll explore how the processes of ...

How can chemical reactions be triggered by light, following the example of photosynthesis in nature? This process is still poorly understood. However, researchers have now uncovered a major piece of ...

Since the early 2000s, the growing level of carbon dioxide in the atmosphere has led to an increased rate of photosynthesis around the world, climate scientists have found. Plants produce energy ...
