 Biology is the study of _____________.  Also examines the relationships among living things  Scientists use the __________________ to study this life. living things Scientific Method

BIOLOGY Bacteri a Image from:

1. Ask a question (based on observation) 2. Form a hypothesis (inference or prediction) 3. Set up a controlled experiment 4. Record and analyze results 5. Draw a conclusion The Scientific Method

No… Rocks are considered non-living matter. Alive?

YES!!! Lithrops: “rock like” plant from South Africa Alive? staff.jccc.net

YES!!! Here the living “Rock” is sitting on some non-living rock. Alive?

1. Made of _________ 2. _____________ 3. Based on a _____________________ 4. _______ and ____________ 5. ______ & ___ ____________& _______ 6. ________ to their ____________ 7. ______________________________ 8. As a group, __________________

The _____ is the basic unit of life. 1. All Living Things Are Made of Cells Multicellular Organisms Unicellular Organisms

All living organisms make other organisms like themselves reproducing in two ways:  Asexual reproduction-  Sexual reproduction- 2. All Living Things Reproduce

 Single celled organisms reproduce this way.  The cell divides creating an exact replica of itself.  Asexual reproduction produces traits the same as the parents.

 Two separate organisms unite to produce an offspring.  Sexual reproduction produces traits different from the parents  This is an advantage as it creates a genetic diversity to assure survival of the species.

 DNA  Inherit traits from the parents  A segment of material with instructions for one trait is called a ________. 3. All Living Things Are Based on a Universal Genetic Code gene

 Grow larger  Differentiation of cell types 4. All Living Things Grow and Develop

 To grow and develop  Metabolism - chemical reaction in which an organism breaks down material 5. All Living Things Obtain & Use Materials & Energy i.ehow.com/images/GlobalPhoto/ Articles/

 ______________ use energy from sunlight or chemicals to make their own food. (green plants use photosynthesis)  ______________ get their energy by consuming other organisms. (animals and most bacteria) 5. All Living Things Obtain & Use Materials & Energy ___________________ AUTOTROPHS HETEROTROPHS image/sun_in_tree.png

 Respond to stimuli 6. All Living Things Respond to Their Environment

 Must be ok on the inside  Homeostasis- process by which an organism keeps its internal conditions stable 7. All Living Things Maintain a Stable Internal Environment

If body temp drops too low, “shivering” produces heat to warm you up. If temp is too hot, “sweating” cools you down. FEEDBACK HOMEOSTASIS involves internal __________ mechanisms

 Living things evolve 8. All Living Things Change Over Time
