1. Characteristics of Living Things
What all organisms have in common

2. Characteristics of Living Things
All ORGANISMS share common characteristics.
Made of Cells
Chemicals of Life (Genetic Material)
Reproduce
Grow and Develop
Obtain and Use Energy
Respond to their Environment
Maintain Homeostasis
As a group, Evolve

3. Vocabulary Organisms: a living thing
Abiotic
Biotic
Non-living things in the environment
Examples:
water, soil, sunlight, oxygen, carbon dioxide
May have some, but not all of the characteristics of living things
Living
Organisms: living things in the environment
Have all of the characteristics of life

4. Made of Cells
Cell: basic unit of structure and function in an organism
Unicellular: made up of one cell (ex. Bacteria)
Multicellular: many cells (ex. Human)

5. Chemicals of Life The cells of living things are all made of chemicals
Cells are made up mostly of water

6. Reproduce Produce offspring that are similar to the parents
Asexual (1 parent ) and sexual (2 parents)
Make more of a species

7. Asexual

8. Sexual

9. Growth and Development
Growth: the process of getting larger
Development: a process of change that occurs throughout an organisms lifetime

10. Obtain and Use Energy Autotrophs Heterotroph “self-feeder”
Organisms require energy to go through life’s processes
Need energy for growth, repair and daily activities
Autotrophs
“self-feeder”
Make and use own food
Example: plants
Heterotroph
“other-feeders”
Must get energy by eating
autotrophs or other heterotrophs
Examples: animals, mushrooms,
slime molds

11. Energy

12. Respond to the Environment
Stimulus: something that causes an organism to react
Ex. Changes in light, temperature, light and sound
Response: an action or change in behavior
Ex. Movement, sweating, blinking

13. Homeostasis Maintaining stable internal condition
Example: sweating to cool your body down
Example: shivering to warm up
Without homeostasis organisms will be sick or die

14. Evolution
Evolution: A gradual change in a species overtime

17. Needs of Living Things Energy Water Living Space Stable internal
Conditions
(Homeostasis)

18. Vocab Transportation: Movement of materials
Excretion: removal of waste materials from a cell (urine, sweat)
Metabolism: all chemical reactions in an organism
Nutrition: body takes in and uses food
Synthesis: combinations of parts to make a whole
