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.

REPRODUCE

The living organism must create more life.

It cannot just be alive itself.

DNA

Living things follow their own pattern of growth.

Some change their appearance, others do not.
