Question
Chapter 24.2, Problem 3CC
Summary Introduction
To suggest:
A hypothesis to explain why the thylakoid membranes of chloroplasts resemble those of cyanobacteria.
Concept introduction:
The cyanobacterial cells contain the chloroplast with the thylakoid membrane. These cells are formed by the fusion of the primitive bacterial cells with the green algae as mentioned in the endosymbiont theory of the origin of mitochondria and chloroplasts.

- In 2010, a bew form of chlorophyll (chlorophyll f) was discovered in cyanobacteria assemblages of stromatolites growing in Shark Bay, Australia. Chlorophyll f has been isolated. and scientists are investigating the structure and function of this pigment. Based on your understanding of photosynthesis, how would you determine the wavelengths of light the pigment absorbs? How would you determine if this pigment plays a role in photosynthesis?
