1.	Assertion: Secondary roots and shoots are plagiogeotropic. Reason: Plagiogeotropic roots are those which develop at an angle of `45^(@)` from the vertical axis.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 assertionC. If the assertion is true but the reason is falseD. If the assertion and reason is false but reason is true
Answer» Correct Answer - A (a) Secondary roots and shoot are plagiofeotropic that is, theygrow to a positionat an oblique angle `(45^(@)`)to the gravitational force. Root and stem brenches lie at an angle other than `90^(@)` to the direaction of gravity.
