11. Section 1.1 Summary – pages 3-10 All living things: have an orderly structure produce offspring grow and develop adjust to changes in the environment Characteristics of Living Things

12. ORGANIZED All organisms are made of one or more cells. Cells are organized into tissues, organs, and organ systems. All organisms reproduce and pass on traits from one generation to the next. REPRODUCE GROW AND DEVELOP ADJUST TO CHANGES IN ENVIRONMENT All organisms get larger (grow) and have a life cycle (develop). All organisms respond to stimulus, use energy and release waste to maintain homeostasis, and adapt and evolve

13. Characteristics of Life CHARACTERISTICS OF LIVING THINGS O. R. G. A ORGANIZED (made of cells) REPRODUCE GROW AND DEVELOP ADJUST/ADAPT

14. The Eight Characteristics of Life 1.1 Introduction to Biology Chapter 1 1. Made of one or more cells 2. Displays organization 3. Grows and develops 4. Reproduces 5. Responds to stimuli 6. Requires energy 7. Maintains homeostasis 8. Adaptations evolve over time

21. Yeast Demo: Day 3

22. If Yeast is Living, what should be true about it? Should be organized Should be able to reproduce Should be able to grow and develop Should be able to adjust Check for cells See if it can make offspring See if you can make it grow See if it uses energy, releases waste, adapts, and responds to stimuli

23. In Your Notebooks… Is Yeast living? How will we test? Make your hypothesis Write down what we will do to find out if yeast is living

24. Observe what happens when we mix yeast, warm water, and sugar.

25. In Your Notebooks… Do you think Yeast is living now? Why or why not? Answer the question

26. What else will do what yeast does?

27. In Your Notebooks… Is baking soda living? Why or why not? Answer the question

28. What is Yeast Used For?

29. HOMEWORK What other test can we do to find out for sure if yeast is living or not? **HINT: How can we test for the other characteristics of life.
