1. Make a two lists Living Nonliving
You have 3 minutes to list everything you see on the next slide as living or nonliving.

3. READ READ READ READ 1. Look at your list.
2. Do you need to change anything from your living list to your nonliving list or nonliving list to your living list.

4. Biology The Study of Life
Recognizing life’s characteristics and the methods used to study life provide a basis for understanding the living world.

5. Principles of Biology
Living things do not exist in isolation; they are all functioning parts in the delicate balance of nature. All living things depend upon other living and nonliving things in a variety of ways and for a variety of reasons.
Leaves of this insect-eating pitcher plant form a tube lined with downward-pointing hairs that prevent insects form escaping. Trapped insects fall into a pool of water and digestive juices at the bottom of the tube.

7. The Pitcher Plant
Name some of the pitcher plant characteristics that make it alive

8. The Diversity of Life
The study of biology will reveal the great diversity of species on Earth and the way each species fits into the dynamic pattern of life on our planet.

9. Characteristics of Life
Organisms in nature possess unique features that allow biologists to identify them as living rather than nonliving. They are as follows:
Organization
Homeostasis
Reproduction
Growth and Development
Response to a Stimulus

10. #1 Organization All living things are organized into Cells
Unicellular - one celled organisms.
Ex. Paramecium, amoeba, stentor
Multicellular – more than one cell.
Ex. Humans, sponges
Cells are not found in nonliving things.
Scanning electron micrograph of Staphylococcus aureus bacteria. 
The five slides that follow are examples of unicellular organisms

11. Paramecium

12. Stentor

13. Amoeba

14. Vorticella

15. Closterium

16. Organisms may be Multicellular

#2 Homeostasis
Regulate external and internal conditions.
Get energy from food.
Use Energy

18. Ability to Reproduce
Reproduction - is the ability to produce a new organism of the same type. It is not essential for the survival of an individual organism, but it is essential for the continuation of a species (a group of organisms that can interbreed and produce fertile offspring in nature).
Asexual - One cell splits into two new cells.
Ex. Paramecium, sponges, strawberry runner, spider plants and other simple organisms usually undergo asexual reproduction.
There are two classifications of reproduction: Asexual and Sexual

19. Paramecium
Undergoing fission

20. Reproduction
Sexual Reproduction - two different cells join to form one new individual. New individual is different from either parent.
Fertilization - union of the egg and sperm.
Zygote - new cell formed as a result of fertilization. Most complex organisms reproduce in this way.

21. Sperm
Egg

22. Growth and Development
Two Basic Kinds of Growth:
Increasing the number of cells.
Increasing the size of the cells.
Development: cycle of changes living things go through as they grow.
Aging process - part of cycle.
Death - end of the cycle.

23. Respond to Environment
Stimulus - a change in the environment
Ex. light shines in eyes.
Response - reaction to the change.
Ex. pupils get smaller.
Vital to any organism
Escape predators
Find food
Move to light
Move away from toxins
Find a mate

24. Importance of Biology
Recognizing life’s characteristics and the methods used to study life provide a basis for understanding the living world.

25. Composition Notebook We will go outside around the school
You will list 20 living and 20 non-living items found in nature.
You can take pictures to include in your composition notebook.
