What are the characteristics of life? What distinguishes a living thing from a non-living thing?

The characteristics of life include the following:

1. Organization: Living things are highly organized and composed of one or more cells, which are the basic units of life. Non-living things do not exhibit such complex organization.

2. Metabolism: Living organisms have the ability to obtain and use energy to carry out various physiological processes necessary for life. They can convert energy from their environment into a usable form for growth, reproduction, and other activities. Non-living things do not possess metabolic processes.

3. Homeostasis: Living organisms have the ability to maintain a stable internal environment despite changes in the external environment. They can regulate their internal temperature, pH level, water balance, and other factors to ensure survival. Non-living things do not possess the ability to maintain homeostasis.

4. Growth and Development: Living things have the potential for growth and development throughout their life cycle. They can increase in size, complexity, and differentiate into specialized cells or tissues. Non-living things do not exhibit such growth or development.

5. Reproduction: Living organisms have the ability to produce offspring either sexually or asexually, ensuring the continuation of their species. Non-living things cannot reproduce.

6. Response to Stimuli: Living things can respond to external stimuli in their environment. They can detect changes and react accordingly. This ability allows them to adapt and survive. Non-living things do not respond to stimuli.

7. Evolution: Living organisms can undergo changes over long periods of time through the process of evolution. They can adapt to their environment, leading to the emergence of new species. Non-living things do not evolve.

These characteristics collectively distinguish living things from non-living things.

What are the characteristics of life? What distinguishes a living thing from a non-living thing?

in one sentence

Living organisms exhibit organization, metabolism, homeostasis, growth and development, reproduction, response to stimuli, and evolution, distinguishing them from non-living things.

What sort of things are hard to classify as one or the other/? Why?

one sentence

Viruses are often difficult to classify as living or non-living because they exhibit some characteristics of life such as replication and genetic material, but lack key features like independent metabolism and cellular structure.

What are chloroplasts? What do they do? Are they found in plant cells, animal cells, or both?

Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, converting sunlight into chemical energy (glucose) and producing oxygen as a byproduct; they are not found in animal cells.

What are mitochondria? What do they do? Are they found in plant cells, animal cells, or both?

Mitochondria are organelles found in both plant and animal cells that are involved in cellular respiration, generating energy in the form of ATP (adenosine triphosphate) through the oxidation of glucose and fatty acids.

What are ribosomes? What do they do? Are they found in plant cells, animal cells, or both?
