NEET Biology Plant Kingdom Question Bank Assertion and Reason

  • question_answer
    Assertion                :       Zygospore of Ulothrix forms meiozoospores and meioaplanospores. Reason                   :       Both are motile.

    A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion

    B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion 

    C) If the assertion is true but the reason is false

    D) If both the assertion and reason are false

    E) If the assertion is false but reason is true

    Correct Answer: C

    Solution :

    The zygospore of Ulothrix, on germination, does not directly develop into a new filament. Instead its nucleus undergoes zygotic meiosis. The resultant four haploid daughter nuclei are organised into meiospores which may be motile (meiozoospores) or non-motile (meioaplanospres).
