Question

Match the following columns related to tropisms in plants

$\begin{array}{cc}\text{Column-I}& \text{Column-II}\\ \text{A.Phototropism}& \text{1.Response to chemicals}\\ \text{B.Gravitropism}& \text{2.Response to light}\\ \text{C.Thigmotropism}& \text{3.Response to physical contact}\\ \text{D.Chemotropism}& \text{4.Response to gravity}\end{array}$

• A. A-1, B - 2, C - 3, D - 4
• B. A - 2, B - 4, C - 1, D - 3
• C. A - 4, B - 3, C - 2, D - 1
• D. A - 2, B - 4, C - 3, D - 1

Answer 1

The correct option is D

A - 2, B - 4, C - 3, D - 1

Plant parts show responses to different environmental factors. Response to light is phototropism, response to gravity is geotropism, response to contact is the thigmotropism and response to chemicals is chemotropism.
