Question

What are 2 characteristics of tropism?

Answer 1

Answer: A tropism is a growth toward or away from a stimulus. Common stimuli that influence plant growth include light, gravity, water, and touch.


Plant tropisms differ from other stimulus generated movements, such as nastic movements, in that the direction of the response depends on the direction of the stimulus.

Answer 2

Two characteristics of tropism are given below.

1) Due to the property of tropism in the plant, roots goes down in the direction of gravity and also goes down in search of water.

2) When seed germinates, the plumule grows in the upper direction in the direction of light due to tropism property. If the property of tropism is not present in plants, the plant does not germinates.
