1. Chapter 1.1 - How to Define Life
Which one of these things would you consider a living organism?

2. A. Living Things Are Organized
subatomic particles --> atoms --> molecules --
cells --> tissues --> organs --> organ systems 

3. Is this organized? Is it life?

4. Each level of organization has emergent properties.
What the heck is an emergent property?
Quality that appears as biological complexity increases as it goes up a level and determined by interactions between individual parts

5. B. Living Things Acquire Materials and Energy
Energy - capacity to do work; it takes work to maintain organization of the cell and organism.                   
 Metabolism - all chemical reactions that occur in a cell.
Organisms must maintain homeostasis -or keep themselves stable in temperature, moisture level, acidity, etc. by physiology and behavior. This maintenance requires energy.

6. Unable to maintain homeostasis?

7. C.  Living Things Respond
1. Living things interact with the environment in order to find nutrients or energy.
2. Responses to environment (stimulus) altogether constitute the behavior of an organism.

8. D. Living Things Reproduce and Develop
Bacteria, protozoans, and other unicellular organisms simply split into two
Multicellular organisms often unite sperm and egg -> zygote
Reproduction assumes that genes are passed from parents to offspring.  DNA is the molecule of life. 

9. E. Living Things Have Adaptations
1. Adaptations - modifications that make an organism suited to its way of life.
2. Natural selection is process by which species become modified over time. 3. Evolution is descent with modification.
This organism is called a pitcher plant.
What do you think its adapted for?

10. RECAP/Exit Slip
What are the characteristics of life?           (try to list them without looking back at your notes)

MOLECULE
ATOM

12. How has the ecosystem in your city been modified?
B. The Human Population
1. Humans modify ecosystems for our own purposes.
2. Some human activity threatens tropical rain forests and coral reefs. 3. Human beings depend on healthy working ecosystems for food, medicines, and raw materials.
How has the ecosystem in your city been modified?
Are these modifications good or bad?

13. Biodiversity
- the total number of species, their variable genes, and their ecosystems.

14. 1.3 How Living Things Are Classified
A. Taxonomy: the Discipline of Identifying and Classifying Organisms
1. Organisms are classified according to their evolutionary relationships.
2. As more is learned about organisms, the taxonomy changes.
How would you group these four organisms?
Two groups?   Three Groups?

15. B. Categories of Classification
1. From larger categories to smaller: kingdom, phylum, class, order, family, genus and species. (King Philip Came Over For Great Soup)
2. In the Kingdoms Plantae and Fungi, the category “phylum” is replaced by “division.”
