Among prokaryotes, only the cyanobacteria _______.

  1. a. live near hydrothermal vents
  2. b. produce oxygen during photosynthesis
  3. c. cannot tolerate oxygen
  4. d. have a nucleus-like structure

Summary Introduction

Concept introduction: Blue-green algae or cyanobacteria are autotrophic organisms that have the ability to survive in almost all types of environments. Many cyanobacteria have the ability to fix nitrogen and are the most self-contained photosynthetic microorganisms. The photosynthesis process is performed on the thylakoids present in the bacteria.

Explanation of Solution

Reasons for the correct statement:

Cyanobacteria have the ability to manufacture their own food by the process of photosynthesis, using various pigments. The color of the pigments gives the common name as blue-green algae. Oxygen is produced by this photosynthesis process.

Option b. is given as “produce oxygen during photosynthesis”. As oxygen is produced in cyanobacteria during photosynthesis, option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “live near hydrothermal vents”.

The organisms that live near hydrothermal vents do not require sunlight and photosynthesis for their food. Only some bacteria and archaea live in these extreme conditions and they use the chemosynthesis process for energy...
