Cyanobacteria and Heterocysts
Cyanobacteria, also known as blue-green algae, are a group of prokaryotic organisms that are found in various aquatic and terrestrial environments. They are photosynthetic and use sunlight to produce energy and organic compounds.
Heterocysts are specialized cells that some cyanobacteria have. They are able to fix atmospheric nitrogen into a form that can be used by the cell. Heterocysts are important for cyanobacteria because, unlike other organisms, they cannot take up nitrogen from the soil. Therefore, they need to be able to produce their own nitrogen.
The incorrect statement about cyanobacteria is option B, which states that they lack heterocysts. In fact, some cyanobacteria do have heterocysts, which are specialized cells that are able to fix atmospheric nitrogen. However, not all cyanobacteria have heterocysts.
Therefore, the correct statement about cyanobacteria is:
- They are photoautotrophs, meaning they use sunlight to produce energy and organic compounds.
- They often form blooms in polluted water bodies, which can be harmful to other organisms in the ecosystem.
- They have chlorophyll A similar to green plants, which allows them to capture sunlight for photosynthesis.
- Some cyanobacteria have heterocysts, specialized cells that are able to fix atmospheric nitrogen.
