Assertion: The apoplastic movement of water beyond the cortex is blocked.

Reason: Major movement of water through cortical cells occurs by this method.

  • A )If both Assertion and Reason are true and Reason is the correct explanation of Assertion
  • B )If both assertion and reason are true but Reason is not the correct explanation of Assertion
  • C )If Assertion is true but Reason is false
  • D )If Assertion is false but Reason is true

Ans is B .

Explanation- Apoplastic movement of water beyond cortex is blocked because of the presence of casparian strips in the endodermis which is made up of lignin and thus provides impermeability to water.

However, in cortical cells maximum movement of water occurs via apoplast as it do not requires any energy and provides rapid and easy flow of water.

Thus , we can say both assertion and reason is correct but reason is not the correct explanation of assertion.

So, the correct option is B
