2. WHICH THINGS ARE ALIVE?

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. MNEMONIC Certain random messy houses have really good apples.

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

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

7. Reproduction is the process of producing new organisms of the same type Asexual Reproduction A single parent organism reproducing by itself A single parent organism reproducing by itself

8. Sexual Reproduction Two different parent organisms contribute genetic information Two different parent organisms contribute genetic information Involves the combination of male and female sex cells Involves the combination of male and female sex cells

9. Living organisms need energy to grow, develop, repair damage, and reproduce

10. A stable state of conditions in the body that are necessary for life Body temperature Body temperature Blood volume Blood volume pH balance pH balance Water balance Water balance Blood Sugar Blood Sugar

11. 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

12. 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

13. Growth means to get bigger in size

14. Development involves a change in the physical form or physiological make-up of an organism… to become more complex

15. Adaptation A process that enables organisms to become better suited to their environment A process that enables organisms to become better suited to their environment Species obtain adaptations through evolution over great periods of time Species obtain adaptations through evolution over great periods of time

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

17. WHAT DO LIVING THINGS NEED? Energy  Needed to carry out life processes, like reproducing and growing  Derived from food  Some organisms make their own food (Producers)  Some organisms eat their food (Consumers)

18. WHAT DO LIVING THINGS NEED? Water  Location of many chemical reactions in living things Gases  Most animals need oxygen  Most plants need Carbon dioxide  Some bacteria use sulfur dioxide

19. WHAT DO LIVING THINGS NEED? Temperature  Organisms that are warm blooded must live in habitats within certain temperature range, and their bodies maintain a constant temperature  Organisms that are cold blooded must be able to change their temperature to match their surroundings Living Space  Need a minimum amount of space to meet the needs above
