Scientists Prove Green Algaes Appetite for Bacteria

A team of researchers is the first to provide definitive proof that green algae eat bacteria. The finding, captured with electron microscope images, offers a glimpse at how scientists think early organisms acquired freeliving chloroplasts, the structures responsible for converting light into food. This event is thought to be a critical first step in the evolution of photosynthetic algae and land plants, which helped raise oxygen levels in Earth s atmosphere and paved the way for the rise of animals.
