Q43 / 200 · MHT CET - Medical 2026 (21 April Shift 1) · Biology

Given below are two statements:
Statement (I): SDP require long uninterrupted dark period for flowering.
Statement (II): If dark period is interrupted even by a flash of light, SDP will flower.
In light of the above statements, choose the most appropriate answer from the options given below.

  • A
    Both Statement (I) and Statement (II) are correct.
  • B
    Both Statement (I) and Statement (II) are incorrect.
  • Correct answer
    C
    Statement (I) is correct but Statement (II) is incorrect.
  • D
    Statement (I) is incorrect but Statement (II) is correct.

Solution

Short Day Plants (SDP) require a continuous, uninterrupted dark period that exceeds a critical duration for flowering to occur. Therefore, Statement (I) is correct.

If this dark period is interrupted even by a brief flash of light, the flowering in SDP is inhibited, and they will not flower. Therefore, Statement (II) is incorrect.

Answer: Statement (I) is correct but Statement (II) is incorrect.

Hence, the correct answer is option: 'C'.
