Question

The given experimental set-up establishes the response of different plant parts towards gravity.
a) Give the scientific term used for such response/movement.
b) How is shoot response different from root response/movement? ​

Answer 1

Answer:

Explanation:

1. GEOTROPISM.

2. SHOOT RESPONSES DIFFERENTLY THAN ROOTS BECAUSE SHOOTS ARE NEGATIVELY GEOTROPIC AND ROOTS ARE POSITIVELY GEOTROPIC.

MOVEMENT OF SHOOTS OCCURS TOWARDS LIGHT BUT AWAY FROM GRAVITY DUE TO ONE SIDE CONCENTRATION OF AUXIN PHYTO HORMONE. BUT ROOTS MOVE AWAY FROM LIGHT BUT TOWARD GRAVITY AND RESPONSE NEGATIVELY TO THE ACTION OF LIGHT.
