What are 7 characteristics of living things?

Answer 1

It is easy to decide whether most objects are living or not. A brick is obviously not living and has never been alive. A dog running around is obviously alive. But what about a leaf that has fallen from a tree? To answer a question like this we need to think about what all living things must do to be alive.

All living things must carry out seven processes to stay alive.

1. All living things obtain energy from their food by a process called RESPIRATION.

2. All living things obtain food by a process called NUTRITION.

3. All living things rid themselves of waste materials by a process called

EXCRETION.

4. GROWTH is another important function of living things. All living things grow.

5. All living things respond to their environment. They therefore require

SENSITIVITY.

6. All living things move. MOVEMENT is an important part of life.

7. All living things get old and die. Replacements are made by the process of REPRODUCTION.

Answer 2

Several contributors have given good answers below.

All living things:

• have a certain size and shape
• are made of one or more cells
• show growth
• move (even plants move or grow towards the light)
• need nutrition (eat food)
• respire (exchange gases)
• excrete wastes
• metabolize (use food)
• respond to stimuli (adapt)
• reproduce

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

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

3. Growth - All living things 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

The characteristics of life are as follows:

1) Must be made up of cells

2) Must be able to metabolize

3) Must react to stimuli

4) Must evolve

5) Must be able to grow

6) Must maintain homeostasis

7) must be able to reproduce

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.

Answer 3

have cells that make the physical basis of life namely protoplasm. Living organisms obtain simple molecules from their surrounding environment, convert them into complex protoplasmic constituents thereby increasing in size and complexity. This phenomenon is called intrasusception (internal growth). Living organisms are capable of utilising, transferring or transforming energy to carry on various life processes. Living organisms have the capacity to produce young ones of their kind. This property is called reproduction. Living organisms show a complex array of biochemical processes, collectively known as metabolism. These activities may be synthetic in nature involving the formation of an organic compound (anabolism) or of destructive nature, involving the breakdown of an organic compound (catabolism). Living organisms exhibit various mechanisms for maintaining a constant state. Living organisms show adaptations to their surrounding environment. Living organisms exhibit the capacity to respond to a stimulus. This property is called as irritability. Living organisms are modified in such a way as to perfectly adapt themselves to the environment in which they live.

Answer 4

Growth, Reproduction, Irritability, Movement, Nutrition, Excretion, Respiration

there is also an acronym called GRIMNER to help you remember it

hoped it was the information you was looking for

Answer 5

1. Made of cells
2. Obtain and use energy
3. Respond to stimuli
4. Grow and develop
5. Reproduce
6. Maintain homeostasis
7. Evolve over time

Answer 6

Movement, reproduction, sensitivity, nutrition, excretion, respiration and growth

This can be remembered by Mrs Nerg.
