1. Levels of Organization Notes Please write TITLE of each slide and the green notes in each box on organizer

2. ATOMS
Smallest part of matter
NON-living

3. Molecules
2 or more bonded atoms
Form compounds
NON-living

4. Macromolecule
Very large complex molecules (polymers) made of a bunch of smaller molecules that are the same (monomers.)
Analogy If you have a pearl necklace. The individual pearls would be the monomer and the necklace would be the polymer.
All living things are made up of proteins, fats, carbohydrates, and nucleic acids.
NON-living
The macromolecules are mainly made of carbon, hydrogen, and oxygen but in different ratios. This gives each compound different properties.

5. Ex: nucleus, mitochondria
Organelles
“Tiny organs”
Made of macromolecules
Non-living
Ex: nucleus, mitochondria

6. Ex: plant cell, skin cell…
Made of organelles
Basic unit of structure & function
LIVING
Ex: plant cell, skin cell…

7. Ex: muscle tissue, nerve tissue
The SIMILAR cells working together
Living
Ex: muscle tissue, nerve tissue

8. Organs
SIMILAR tissues that work together
Living
Ex: heart, stomach…

9. Ex: skeletal system, nervous system
Organ Systems
Organs that work together for similar purpose
Living
Ex: skeletal system, nervous system

10. Organism Ex: human, dog Entire living things (organisms)
Usually made of systems
May be a single cell
Living
Ex: human, dog

11. Population
Same organisms living together
Ex: group of penguins

12. Ex: penguins, polar bears
Community
Several populations living together
Populations interact
Ex: penguins, polar bears

13. Ecosystem
A biotic (living) community and the abiotic (nonliving) features
Ex: penguins, polar bears, temperature, & sun

14. Biome
Similar ecosystems on earth together
Ex: arctic tundra

15. Biosphere Whole living layer on Earth Includes abiotic features

16. Tissue Organ System Organism Atom Molecule Macromolecule Organelle

20. Think, Pair, Share:
Can you put the following items in order from smallest to largest? Organ, Cell, Organ System, Tissue, Organism
**Think to yourself first! Then quietly discuss with table partner…be ready for me to call on you to share!
