1. Characteristics of Living Things

2. Honors Biology
Take out scientific method worksheets. HW: Mythbusters due by 9/19 Unit test 9/12 Body systems quiz 9/10

3. All Living things are made up of cells.

4. What is a Cell? Basic building blocks of all living things.
Perform all of the functions of life

5. What are two types of cells?
Prokaryotic – Simple cell, no nucleus or membrane bound organelles.
Ex. Bacteria
Eukaryotic- Complex cells, has a nucleus and membrane bound organelles.
Ex. Animals, Plants, Fungus, Protist

6. Two types of cells
Prokaryotic
Eukaryotic

7. Unicellular vs. Multicellular
Unicellular-one cell
Multicellular- many cells, specialization

8. Levels of Organization
Atom
Cell
Tissue
Organ
Organ system
Organism

9. 11 main body systems Nervous system Endocrine system
Integumentary system
Muscular system
Skeletal system
Urinary system
Respiratory system
Reproductive system
Circulatory system
Digestive system
Lymphatic system

10. Homework Determine the function of each of the 11 human body systems.
Identify at least two organs that are involved with each system.

11. All Living Things Reproduce.

12. Two Types of Reproduction
Sexual Reproduction
Two Parents
Genetically diverse (different genes than parents)
Asexual Reproduction
One Parent
Genetically identical (same genes as parent)

13. All Living Things Adjust to Their Surroundings.
Homeostasis
Maintain internal control
Example: body temperature, glucose, water and pH levels in the blood are maintained at a constant rate.

14. Homeostatic mechanisms
The process by which an organism monitors and maintains a constant state.

15. Negative feedback loop
Any change to a system causes the system to return to its original state.
Osmoregulation
Thermoregulation
Blood pH and Blood glucose levels

16. Positive feedback loop
Amplifies a change in the system, causing it to move farther and farther from its original state.
Examples: childbirth and ripening fruit
Video explanation

17. Positive Feedback Loop Example

18. Negative Feedback Loop

19. All Living Things Grow and Develop.
Growth
Increase in size
Development
changes that happen as you grow
To become more complex

20. All living things have complex chemistry
Consists of complex molecules that go through chemical changes to stay alive.

21. All Living Things Can convert energy to food.
Or convert food to energy.
Main source of energy for all living organisms is the SUN
Producer: make their own food. Ex plants
Consumer: Must take in food to survive

22. All living things….. Respond to their environment
Adaptation: any alteration in the structure or function of an organism or any of its parts that results from natural selection and by which the organism becomes better fitted to survive and multiply in its environment.

23. Four unifying principles
Cell theory
Cells are the basic unit of life
All living things are made up of cells
Cells come from other cells.

24. Four unifying principles
Gene Theory
Genes determine the characteristics of living things.
They are located on chromosomes that are found in every cell.
Genes are passed on from parents to offspring.

25. Four Unifying principles
Homeostasis
Keeping internal conditions constant even though the external environments change

26. Four Unifying Principles
Evolution
Occurs by the process of natural selection.
Organisms become more suited to their environments through evolution because they develop adaptations.

27. Create a Keystone Card
Use pages in the Keystone books to complete drawings for.
Thermoregulation
Osmoregulation
Gas exchange
Regulation of blood glucose
