You should read as many of the other students’ posts as time permits since you may get a better understanding of photosynthesis and pigments in the process.
You should also then write a response to at least two other students. In your response be sure to address the description of photosynthesis and the chosen pigment. Ask any clarifying questions to expand upon your understanding.
