6. Biology: The Study of Life ! Recognizing life’s characteristics and the methods used to study life provides a basis for understanding the living world.

7. The Diversity of Life The study of biology reveals the great diversity of species on Earth and the way each species fits into the dynamic pattern of life on our planet. But how are all living things connected? Click HERE to explore a multitude of diverse organisms.HERE

They are as follows:

Plan for 8/26-8/30 M: Internet Scavenger Hunt DUE TUES Reading: p. 17-19 DUE FRI T: COL Station Lab; maybe notes… BLOCK : Finish COL Stations TURN IN ; COL Poster DUE FRI F: Reading quiz 1 : p. 17-19 (Every week you will have a reading quiz, and will be allowed to use anything you wrote yourself)

11. Notes on 1.3…

12. #1 Cellular 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. 8/26/13

14. #2 Homeostasis  Regulate internal conditions. #3 METABOLISM  Obtain (get) and use energy Click HERE to see a demonstration of hypothermia.

15. #4 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

16. Reproduction Asexual - One cell splits into two new cells. simple organisms usually undergo asexual reproduction Ex. Paramecium, sponges, strawberry runner, bacteria

17. Reproduction Sexual Reproduction - two different cells join to form one new individual.  New individual is genetically different from either parent.

18. #5 Have Genetic code (DNA)

19. #6 Growth and Development  Two Basic Kinds of Growth: Increasing the number of cells. Increasing the size of the cells.  Development: Chemical and physical changes living things go through as they grow. (ie. Puberty, aging)

20. #7 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

21. #8 Can Evolve (as a group)
