6 Characteristics of

Living Things

Living, Dead(Once Living),

Non-living

How can you tell the difference?

Living Things

• Living things have 6 characteristics:1. All living things have cells2. All living things have DNA3. All living things grow and develop4. All living things respond to stimuli5. All living things have metabolism6. All living things reproduce

Living Things

All Living Things Have Cells• A cell is the basic unit of life• A cell controls all the

activities of the organism– AN ORGANISM IS ANY LIVING

THING

• A living thing can be multicellular (lots of cells)

• A living thing can be unicellular (one cell)

1. All living things have cells2. All living things have DNA3. All living things grow and develop4. All living things respond to stimuli5. All living things have metabolism6. All living things reproduce

Living Things

All Living Things Have DNA• DNA is a special chemical

inside the cell that controls all the activities.

• DNA stands for deoxyribonucleic acid.

• It makes you who you are (genes).

1. All living things have cells2. All living things have DNA3. All living things grow and develop4. All living things respond to stimuli5. All living things have metabolism6. All living things reproduce

Living ThingsAll Living Things Grow and Develop• Grow by getting bigger.• Develop by changing

– Get permanent teeth– Voice deepens– Change from a seed to a tree

1. All living things have cells2. All living things have DNA3. All living things grow and develop4. All living things respond to stimuli5. All living things have metabolism6. All living things reproduce

Living Things

All living things respond to stimuli• Stimuli – something that

happens in the environment– Sun shining– Cold

• Response – what you do– Pupils contract– Shiver

HOMEOSTASIS is your bodymaintaining a stable internalenvironment (bear growing a fur

coat to stay warm)

1. All living things have cells2. All living things have DNA3. All living things grow and develop4. All living things respond to stimuli5. All living things have metabolism6. All living things reproduce

Living Things

All living things have metabolism• Use energy

– Move– Respiration– Excrete waste– Need nutrition

1. All living things have cells2. All living things have DNA3. All living things grow and develop4. All living things respond to stimuli5. All living things have metabolism6. All living things reproduce

Living Things

All living reproduce• Make new cells• Have offspring

1. All living things have cells2. All living things have DNA3. All living things grow and develop4. All living things respond to stimuli5. All living things have metabolism6. All living things reproduce

Once Living Things(Dead)

Was living at one time but is no longer alive.• Pencil (wood from a tree)• Dinosaur

1. All living things have cells2. All living things have DNA3. All living things grow and develop4. All living things respond to stimuli5. All living things have metabolism6. All living things reproduce

Non-LivingIn order to consider something non-living it must not have any of the 6 characteristics that living organisms have.

or

It was living or dead and has been processed (chemical change).

rock, dirt, water

paper, apple juice, oil

Summary

• LIVING• Has all 6

characteristics necessary to living things

• NON-LIVING• Does not

have all 6 things necessary to living things

•DEAD • Used to

have all 6 characteristics necessary to living things, but doesn't anymore

Example: Tree

Example: Paper
