Photosynthetic bacteria are the group of bacteria which has the ability to consume energy in sunlight to produce chemical energy. There are 2 types of photosynthetic bacteria as oxygenic photosynthetic bacteria & anoxygenic photosynthetic bacteria. Oxygenic bacteria produce gaseous oxygen (O 2 ) as a side product of photosynthesis while anoxygenic bacteria don’t.

Summary Introduction

Introduction:

Photosynthetic bacteria are the group of bacteria which has the ability to consume energy in sunlight to produce chemical energy. There are 2 types of photosynthetic bacteria as oxygenic photosynthetic bacteria & anoxygenic photosynthetic bacteria. Oxygenic bacteria produce gaseous oxygen (O₂) as a side product of photosynthesis while anoxygenic bacteria don’t.

Expert Solution & Answer

Answer to Problem 1TY

The correct answer is option (b) the cyanobacteria

Explanation of Solution

Explanation/justification for the correct answer:

Option (b) thecyanobacteria. Cyanobacteria are also type of phototropic bacteria. They can perform photosynthesis which is similar to the green plants in mechanism. Therefore cyanobacteria are the phylum of bacteria which produce oxygen gas as a result of photosynthesis. So this is the correct answer.

Explanation for incorrect answer:

Option (a) the proteobacteria. Proteobacteria is a sub group of gram-negative bacteria. They can perform photosynthesis with the bacteriochlorophylls a & b. But proteobacteria are a type of anoxygenic bacteria. Therefore option (a) is incorrect.

Option (c) the Gram-positive bacteria. Gram-positive bacteria also have some species that are photosynthetic. But they are also anoxygenic bacterial type.

Option (d) all of the above. As option (a) and (c) are incorrect, option (d) also incorrect.

Option (e) none of the above. As option (b) is correct this option is wrong.

Conclusion

The phylum of bacteria which produce oxygen gas as a result of photosynthesis is cyanobacteria. So the correct option is option (b).
