Biology is the study of living things
“bio” means “life”“-logy” means “the study of”
So… biology is when we study life!

But how do we know if it is alive?
• There are 7 things that are true about all living things
• Scientists call them the
“Characteristics of Life”

Made up of Cells
Every living thing is made up of one or many cells.
When there is only one cell = unicellularWhen there are many cells = multicellular

Reproduction
Every living thing reproduces.
When there are 2 parents = sexual reproduction
When there is only 1 parent = asexual reproduction

Growth & Development
All living things grow and develop.
When you increase in size = grow
When your cells change = development

Need for Materials & Energy
Every living thing needs energy.
Autotrophs make their ownfood
Heterotrophs get food byeating others

Response to the EnvironmentEvery living thing
responds to its environment.
A stimulus= something that makes you react (ex. noise, light, temperature, or touch)

Maintaining Internal Balance
All living things maintain homeostasis (maintaining an
internal balance) in their body.
Homeostasis is bringing your body back to normal (ex. Too hot, too cold, Dehydrated, hungry)

Evolution
All living things evolve.
Evolution is when a species changes over time

How will I remember all 7? Watch Video
All living things:– Evolve– maintain Homeostasis– Grow and Develop– are made of one or many
Cells– obtain and use Energy– Reproduce– Respond to the environment
