Question

Which of these break up into smaller pieces upon maturation?

• A. Rhodella
• B. Spirogyra
• C. Caulerpa
• D. All of the above

Answer 1

The correct option is B Spirogyra

• Spirogyra is a genus of filamentous green algae which reproduce by fragmentation. The body of Spirogyra on maturing simply breaks up into smaller pieces or fragments. These pieces or fragments then grow into new individuals.
• Rhodella is reproduced through binary fission.
• Caulerpa is reproduced through zoospores, and also vegetative and sexual reproduction is present.

Thus, the correct answer is option (B), 'Spirogyra'.
