WHAT MAKES SOMETHING ALIVE?

The biological answer is that there are 8 characteristics all living things share:

• They are made up of cells.• They reproduce.• They have DNA.• They grow and develop.• They consume and use material and energy.• They respond to stimuli.• They maintain a stable environment inside.• They change over time.

MADE UP OF CELLS

Cells are the smallest unit of life and all things bigger are made of cells.

Think of the Cell Theory.

REPRODUCE

The living organism must create more life.

It cannot just be alive itself.

DNA

Deoxyribonucleic Acid

All life has it…

GROW AND DEVELOP

Living things follow their own pattern of growth.

Some change their appearance, others do not.

CONSUME AND USE ENERGY

Living things must intake and use energy.

Plants use sunlight, animals eat other living things.

RESPOND TO STIMULI

If it is touched, it will react.

Any signal organism get, there is a reaction.

What are some stimuli we react too?

HOMEOSTASIS

Organisms keep their organs in a stable condition

We don’t like getting too hot or too cold.

ADAPTATION AND EVOLUTION

Organisms will change over time.

Also, they adapt to their environment.
