Question

9. A farmer arranged support for cucumber plant, so that they creep and grow in
a normal condition. What type of trophic movement is shown by cucumber?
O 1) Phototropism
O2) Geotropism
O 3) Hydrotropism
O 4) Thigmotropism​

Answer 1

Answer:

4

Explanation:

The stem of the plants like cucumber and bitter gourd are very thin and slender. The stem shows the property of thigmotropism. 

This is the phenomenon in which there is a movement like the bending or the curling of the stem. 

Whenever there is stimulus received in the form of touch, there is curling of the stem and the tendrils of the plant. 

This provides support to the plant in climbing against the surfaces.
