Biology – The Study of Biology – The Study of LifeLife

Life arose more than 3.5 billion years ago

First organisms (living things) were single celled

Only life on Earth for millions of years

Organisms changed over time (evolved)

What is Life? How do we know something is

living?


7 Characteristics of Living Things 1. All living things are made of cells.

Cells are the basic unit of life. 2. All living things uses energy.

Energy comes from the sun. 3. All living things respond to

stimulus (stimuli- pleural). Stimulus- change in environment

(hot= sweat)


7 Characteristics of Living Things 4. All living things reproduce.

Sexual or asexual 5. All living things grow and

develop. 6. All living things change to fit

their environment (adapt). If not, they risk becoming extinct.


7 Characteristics of Living Things 7. All living things have DNA.

DNA provides instructions for making molecules called proteins. Proteins build cells.

DNA carries the genetic material from parent to offspring (heredity).
