1. Mindstretcher What are the four basic types of tissues in the human body? Briefly list what they do. **Read the organizer first and then write your answer! You may highlight/underline too! Muscle- move body parts Connective- provides support Nerve- transmits messages Epithelial- provides protective outer coating (skin)

2. Levels of Organization Notes *Complete on the organizer provided

3. ATOMS Smallest part of matter NON-living

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

5. 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 just four macromolecules: proteins, fats, carbohydrates, and nucleic acids. NON-living

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

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

8. Tissue The same kind cell working together Living Ex: muscle tissue, nerve tissue

9. Organs Tissues that work together Living Ex: heart, stomach…

10. Organ Systems Organs that work together Living Ex: skeletal system, nervous system

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

12. Population Same type of organism living together Ex: group of penguins

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

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

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

16. Biosphere Whole living layer around the globe Includes abiotic features http://people.hofstra.edu/geotrans/eng/ch8en/conc8en/envisys.html

17. Atom Molecule Macromolecule Organelle Cell Tissue Organ System Organism Population Community Ecosystem Biome Biosphere
