NEET Biology Plant Kingdom Question Bank Assertion and Reason

  • question_answer
    Assertion                :       Unlike thallophytes, bryophytes show formation of embryo. Reason                   :       The embryo gives rise to gametophyte plant of bryophytes.

    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 :

    Thallophytes, i.e., algae and fungi completely lack the formation of embryo. In bryophytes, the zygote, on germination, does not produce the gametophyte plant. It undergoes segmentation to form an embryo. The embryo (diploid) by further segmentation and differentiation gives rise to sporophyte. The sporophyll obtains its nourishment directly from the parent gaemtophyte to which it is organically attached.
