2. What is Biology? BIOLOGY is the study of life. Living things are called ORGANISMS. o Include animals, plants, fungi, protist, and bacteria.

3. All living things share some basic properties. Cellular Organization Cellular Organization Reproduction Reproduction Metabolism (Obtain and Use Energy) Metabolism (Obtain and Use Energy) Homeostasis Homeostasis Heredity Heredity Responsiveness Responsiveness Growth and Development Growth and Development Adapt Through Evolution Adapt Through Evolution

4. Unicellular Organisms Entire organism is made up of one single cell Entire organism is made up of one single cell Example:Bacteria and protists Example:Bacteria and protists Smallest unit capable of all life functions

5. Multicellular Organisms The organism is made up of many cells The organism is made up of many cells Cells have special functions within the organism Cells have special functions within the organism

6. Reproduction is the process of producing new organisms of the same type Asexual Reproduction When a new organism is formed from one parent When a new organism is formed from one parent

8. Sexual Reproduction When a new organism is formed form two parents When a new organism is formed form two parents Involves the combination of male and female genetic information Involves the combination of male and female genetic information

10. Living organisms need energy (nutrition=food) to grow, develop, repair damage, and reproduce Autotrophic- organisms can make their own food Heterotrophic- organisms cannot make their own food

12. SYNTHESIS The process of building up complex substances from simpler substances Building up cells and cellular components Photosynthesis

13. Digestion The process of breaking down complex substances into simpler substances to release energy

14. Metabolism The total of all chemical activities in an organism *Metabolic processes use chemical reactants and result in chemical products and wastes.

15. An organism’s stable internal environment Examples: Body temperature Body temperature Blood volume Blood volume pH balance pH balance Water balance Water balance Video

16. Transport *Process by which substances are absorbed and released *Materials are circulated within an organism

17. Organisms react to stimuli: Light Light Temperature Temperature Odor Odor Sound Sound Gravity Gravity Heat Heat Water Water Pressure Pressure An example is a plant’s leaves and stems growing toward light

19. Genes carry hereditary information Genes are composed of DNA Heredity is the reason children resemble their parents Mutations change DNA code and can be passed from generation to generation

20. Growth means to get bigger in size

21. Development involves a change in the physical form or physiological make-up of an organism

22. Adaptation When an organism makes a change that will increase its chances of survival in its natural habitat When an organism makes a change that will increase its chances of survival in its natural habitat Species obtain adaptations through evolution over great periods of time Species obtain adaptations through evolution over great periods of time

24. An Example of Adaptation Desert plants have succulent waxy leaves and stems to store water and reduce water loss
