Question

Match the terminology in Group I with the stimulus in Group II that generates growth response of plants

Group I	Group II
P. Gravitropism	1. Light
Q. Phototropism	2. Touch
R. Thigmotropism	3. Chemical
S. Chemotropism	4. Gravity

• A. P – 3, Q – 4, R – 2, S – 1
• B. P – 2, Q – 1, R – 3, S – 4
• C. P – 4, Q – 1, R – 2, S – 3
• D. P – 4, Q – 2, R – 1, S – 3

Answer 1

The Correct Option is C

Gravitropism refers to growth towards or away from gravity. Phototropism involves a response to light. Thigmotropism is a response to touch, seen in climbing plants. Chemotropism is the response to chemical stimuli, such as pollen tube growth.
