Assertion : Storage of seeds at low temperature is possible.

Reason : Respiration and enzymatic activity are not shown by seeds at low temperature.

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  5. If the assertion is false but reason is true
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Some seeds are capable of withstanding exposure to low temperature (-10C to -20C). Some of properly dried seeds can withstand low temperature of even liquid nitrogen (- 196C). This reduces respiration and enzymatic activity to bare minimum which is required for sustaining the living of the seeds. Samples of the seeds are periodically tested for germination ability.

So, the correct answer is 'If the assertion is true but the reason is false'
