The correct Answer is:
To solve the question regarding the common mode of multiplication in cyanobacteria, we will analyze the options provided and determine which one is correct based on the characteristics of cyanobacteria. ### Step-by-Step Solution: 1. **Understanding Cyanobacteria**: - Cyanobacteria, also known as blue-green algae, primarily reproduce asexually. 2. **Analyzing the Options**: - **Heterocyst**: - Heterocysts are specialized cells in cyanobacteria that are involved in nitrogen fixation. They do not play a role in the multiplication of cyanobacteria. Therefore, this option is incorrect. - **Exospore**: - Exospores are a type of spore found in some bacteria, but they are not present in cyanobacteria. Hence, this option is also incorrect. - **Hormogone**: - Hormogones are fragments of the filament (trichome) that can break off and grow into new individuals. This is a common mode of asexual reproduction in cyanobacteria. Therefore, this option is correct. - **Trichome**: - A trichome refers to the filamentous structure of cyanobacteria. While it is a part of their structure, it does not represent a mode of multiplication. Thus, this option is incorrect. 3. **Conclusion**: - After analyzing all the options, the correct answer is **Hormogone**, as it is the common mode of asexual reproduction in cyanobacteria. ### Final Answer: The common mode of multiplication in cyanobacteria is **Hormogone**. ---
