Question

What is the difference between positive response and negative response?

Answer 1

Response:

1. In plants, response refers to the reaction against a stimulus at a specific area of electrochemical nature called the responsive region.
2. The stimulus transmits from the perception region to the responsive region.
3. Plants show two types of responses: positive and negative.
4. The difference between positive and negative responses in plants is given in the table below.

Positive Response	Negative Response
When the response generated by plants against a stimulus is towards the stimulus, the response is called a positive response.	When the response generated by plants against a stimulus is away or not in favour of the stimulus, the response is called a negative response.
An example of a positive response is positive phototropism.	An example of a negative response is negative geotropism.
