Question

Which of the following is a characteristic of living things?

• A. Living organisms are highly organized, coordinated structures that consist of one or more cells
• B. Living things respond to diverse stimuli
• C. All organisms use a source of energy for their metabolic activities
• D. All of the above

Answer 1

The correct option is D

All of the above

The correct option is D

Explanation of the correct option:

1. All living organisms share several essential features or functions, like order, sensitivity or response to stimuli, regulation, growth and development, energy processing, etc.
2. The living organisms are highly organized compositions, which comprise one or many cells.
3. Single-celled organisms are very complex, that is, within each cell, the atoms from the molecules, and these, in turn, give rise to organelles or cell components.
4. The multicellular organisms comprise millions of individual cells and thus exhibit an advantage over the single-celled species as their cells can be specialized to do unique activities.
5. Living organisms react to different kinds of stimuli, like plants can bend toward a light source or react to touch.
6. All living organisms utilize an energy source to do their metabolic activities. Some species like plants captivate energy from the Sun and transform it into chemical energy by the process known as photosynthesis.

Final answer: Some of the essential characteristics of living things are:

1. They are highly organized, coordinated compositions, which comprise one or more cells.
2. They react to diverse stimuli.
3. All living things use an energy source for their metabolic functions.
