2. MRS. C. GREN These 8 characteristics tell us if something is alive
M movement
R respiration
S sensitivity
C Cells
G growth
R reproduction
E excretion
N nutrition
These 8 characteristics tell us if something is alive

3. Movement Plants grow towards the sun; a response called phototropism
Animals move to find food or shelter; people move for activity
Microorganisms can swim using cilia or flagella.

4. Respiration
Glucose + Oxygen Carbon dioxide + Water + ENERGY
This reaction takes place in every cell in every plant and animal……learn it!

5. Sensitivity This means detecting changes in your surroundings.
A Venus fly trap detects an insect.
And of course we have our senses!

6. Cells All living things are made of cells or are
Single celled organisms.

7. This one’s obvious…..we all grow. Some taller than others!
Growth
This one’s obvious…..we all grow. Some taller than others!
To be alive we must be able to grow.

8. Reproduction Organisms make more of themselves
To keep the species alive
There are two ways to reproduce:
Sexually and asexually
Sexual reproduction requires two of the species
Asexual (“a” means “not”) only requires
One member of the species

9. EXCRETE
All living things must get rid of waste.

10. Nutrition Living things need the correct nutrition to keep
them healthy and alive.

11. MRS C. GREN Characteristics of life That’s it!
This is the mnemonic for remembering the
Characteristics of life
Do you think this will be on the next quiz?
Well, dag nabbit it sure will be!
Gee, should I practice memorizing this?
Only if you want to learn and get wrinkles in your brain!
