What is the characteristic where living things respond to stimuli?

All living things are able to respond to stimuli in the external environment. For example, living things respond to changes in light, heat, sound, and chemical and mechanical contact. To detect stimuli, organisms have means for receiving information, such as eyes, ears, and taste buds.

How are stimuli detected?

Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.

Can viruses respond to stimuli?

Viruses – The Boundary of Life In isolation, viruses and bacteriophages show none of the expected signs of life. They do not respond to stimuli, they do not grow, they do not do any of the things we normally associate with life. Strictly speaking, they should not be considered as “living” organisms at all.

Does bacteria have a brain?

Bacteria do not have brains or other organs. Even their one cell looks much simpler than one of our own cells. Even so, bacteria can defend themselves from viruses a lot like we do. Then the bacteria are protected from infection.

Do bacteria have intelligence?

Microbial intelligence (popularly known as bacterial intelligence) is the intelligence shown by microorganisms. Even bacteria can display more sophisticated behavior as a population. These behaviors occur in single species populations, or mixed species populations.

Do cells have emotions?

NO. Therefore they can not have emotion. They can’t think from your perspective.

Do our cells think?

The short answer is that cells do not have brains. So they don’t have brains, but have simple systems that work like very basic brains. They can’t think,”I’ll go over there,” but they can have chemical reactions that make them move toward the side of a dish that has more light.

Do plants scream when they are cut?

Plants feel pain too! Researchers find an ultrasonic ‘scream’ is emitted when stems are cut or if species are not watered enough. A team of scientists at Tel Aviv University have discovered that some plants emit a high frequency distress sound when they undergo environmental stress.
