Question

One-celled organisms can respond to stimuli.

• A. True
• B. False

Answer 1

The correct option is A True

Response to stimuli also known as sensitivity is shown by all the living organisms whether it is unicellular or multicellular. This is essential for one-celled organisms for their survival. For example, if a unicellular organism is exposed to a chemical, it will react either by producing another chemical or by moving away from the stimulus to survive.

Thus, the correct answer is option A.
