1. What are living things?

2. 5 characteristic's that living thing share
Made up of one or more cells
Respond to their environment
Use energy
Grow and mature
Living things Reproduce

3. : Unicellular or Multicellular
Multicellular animals have more than one cell
Ex. Lion
Unicellular organisms are made up of one cell
Ex. Paramecium

4. Multicellular Organisms
Cells have specialized functions in a multicellular organism.
Ex. Blood cell has a specific job to do. One job is to carry oxygen through out the body
Skin cell has a specific job to do they protect your body

5. Respond to their environment
Stimulus and Response
Stimulus – A change that affects the activity of that organism
Response – how the organism reacts

6. Stimulus and Response Stimulus- you are cold
Response – Goose bumps on skin

7. homeostasis The maintenance of a stable internal environment
Ex. Your body sweats when it gets too hot; sweating helps control your body temperature at a comfortable level.

8. Living Things Need energy to survive.
What are some ways organisms get their energy?

11. Grow and mature Living things grow
Unicellular organisms grows by getting larger and then dividing
Multicellular organisms grow by increasing the number of cells and they get bigger

12. Reproduction animals reproduce
Sexual reproduction results in diverse offspring. Two parents
What does this mean: diverse offspring?
Asexual reproduction – single parent produces offspring whose genetic material is identical to its parent

13. What do living things need to survive?
Almost all living things need:
water,
air,
food
a place to live
Water is essential for life
Organisms often compete for food, water and a place to live

14. Invertebrates Animals without a backbone. Have no bones
Exoskeleton – external covering function is to support the body
95% of the animal population are invertebrates!

15. Invertebrates
Jellyfish
Flatworms, segmented worms
Sponges

16. Vertebrates Contain a backbone Endoskeleton – skeleton inside body
Vertebrae- protect part of the nervous system
Skull- protect brain
vertebrates reproduce sexually
