Assertion : On plotting the length of the root against time, a linear curve is obtained.
Reason : An elongating root exemplifies arithmetic growth.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false
- DIf both assertion and reason are false
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
In arithmetic growth, following mitotic cell division, only one daughter cell continues to divide while the other differentiates and matures. The simplest expression of arithmetic growth is exemplified by a root elongating at a constant rate. On plotting the length of the organ against time, a linear curve is obtained.
