13 Prokaryotes Photosynthetic cyanobacteria gave earth its first oxygen atmosphere 1.8 billion years ago Beneficial or pathogenic bacteria in animals & humans Nitrogen-fixing bacteria & archaea have profound effect on the productivity of natural ecosystems and agroecosystems 14 Cyanobacteria Gave Earth its first oxygen atmosphere starting 1.8 billion years ago Possess chlorophyll that is not bounded by membranes into organelles like chloroplasts Currently discussed theory on origin of chloroplast suggests that: cyanobacteria-type organisms became incorporated into early eukaryotes and evolved into chloroplasts (Fig 28.3)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
