What are the 7 characteristics of life?

1. Cells - All living thinks have cells; cells are the building blocks of life.

2. Metabolism - All living things eat, drink, breathe and excrete.


3. Growth - All living thinks take in material from the environment to enlarge.


4. Reproduction - All living things are able to produce a copy of themselves.


5. Irritability - All living things are able to react to a change in their environment.


6. Adaptation - All living things are able to compete with each other for food and space to survive.


7. Movement - All living things are able to move.






Could also be:

1. organized
2. metabolism
3. response
4. growth
5. homeostasis
6. reproduce
7. adaptation

I KNOW THEY ARE SIMILAR BUT SOME ARE DIFFERENT AND MINE CAME FROM MY HONORS BIOLOGY NOTES!!






Actually, movement is not a characteristic of life, as there are many different living things that can not move by themselves. Examples would be most plants, such as trees. and, what exactly do you mean by "Organized in your second set of characteristics?


The characteristics of life are as follows:

1) Must be made up of cells

2) Must be able to metabolise

3) Must react to stimuli

4) Must evolve

5) Must be able to grow

6) Must maintain homeostasis

7) must be able to reproduce




Okay this is what I think (Natasha050) :

1. Life has organization.

As an organism lives, it maintains its organization by using different processes. Living organisms are organized from the simplest to the most complex. Atoms make up molecules. Molecules make up cell organelles. Cell organelles make up cells. Cells make up tissues. Tissues make up organs. Organs make up organ systems, and organ systems make up an organism. The way these are arranged determines the type of organism produced.

2. Life needs to acquire energy.

Living things must acquire nutrients so that they can be used to build and maintain the structures of an organism. Energy is needed to maintain the work done by the organism.

3. Homeostasis.

The internal environment stays the same despite an ever changing external environment.

4. Respond to stimuli.

An organism responds to stimuli by moving. These behaviors are done to minimize injury, to reproduce, and to gather a food source. All living things interact with the external surroundings.

5. Must be able to reproduce.

Organisms must be able to pass on the organism's hereditary information.

6. Must be able to grow and develop.

Organisms increase in size and the number of cells they possess. Human development includes all changes that take place from birth to death. The parts of an organism and their arrangement are related to the function.

7. Adaptions.

These are changes to an organism so that it is best suited to its own environment.
