Answer:
Option A, accumulate sulfur as intracellular granules.
Explanation:
Purple sulfur bacteria belong to the group of Proteobacteria. These probacterias are anaerobic in nature and yet are able to photosynthesise. They are usually found in water environments such as hot springs, stagnant water etc. They use sulphur (either in the form of sulfide, or thiosulfate) as an electron donor in their photosynthetic activity to oxidise sulfur thereby producing granules of elemental sulfur.
while filamentous sulfur oxidizers use nitrate instead of oxygen to oxidize sulfide thereby producing granules.
Hence, option A is correct.
Answer:
C. glucose
Explanation:
Dark reaction takes place outside the thalakoid membrane (stroma and cytoplasm). During dark reactions, energy is released from ATP and NADPH to fix carbon dioxide into <em><u>glucose</u></em>.
Option A and B are not correct because they are produced during light reactions. Likewise, chlorophyll is the part of cell and is not prepared during light or dark reactions at all.
Proteins, carbohydrates, nucleic acids, and lipids
The correct answer to your question is the last one; how species change over time.
Hope that helps!
