Incorrect Sentence about Algae:
The incorrect sentence written by Paheli is:
  • Spirogyra is single-celled algae.



Explanation:

Spirogyra is single-celled algae:
Paheli's statement that Spirogyra is single-celled algae is incorrect. Spirogyra is actually a filamentous green algae consisting of multicellular filaments. Each cell within the filament contains a single nucleus, making it a multicellular organism.
  • Chlamydomonas and diatoms are multi-celled algae:
    This statement is correct as both Chlamydomonas and diatoms are examples of multicellular algae.
  • Blue-green algae can not fix nitrogen gas of atmosphere:
    This statement is also correct. Blue-green algae, also known as cyanobacteria, are capable of fixing nitrogen from the atmosphere and converting it into a form that plants can use for growth.
