{ bidder: 'appnexus', params: { placementId: '11654174' }}, Thank you for suggesting a definition! These three groups make up the monophyletic group, Archaeplastida. According to one view, they are vestigial spores. 4. While the thylakoid machinery for electron transport is used for photosynthesis in the light (during the day) it is then used for respiration in the dark (at night). The name “cyanobacteria” comes from the color of the bacteria (Greek: κυανός (kyanós) = blue).

There are different views about the nature of heterocysts. “So we kept looking around,” Woo said, saying the next option was photosynthetic bacteria called cyanobacteria because it is “more rugged” and could survive with heart cells in a petri dish.
