3. Know How do you know something is living? Evidence Page 11 Make 6 sketches below showing characteristics of living things.

4. Characteristics of living things - Organisms that are made up of only one cell - Organisms that are made up of only one cell unicellular Clarifying ?s Information Page 12 multicellular - Organisms that are made up of many cells - Organisms that are made up of many cells Example: amoeba, paramecium Example: We are multicellular. 1. Cellular organization Living vs Non-living

Clarifying ?s Information Page 12 multicellular - Organisms that are made up of many cells - Organisms that are made up of many cells Example: We are multicellular. carbohydrates - Source of energy for living things - Source of energy for living things Proteins + lipids - Building materials for organisms - Building materials for organisms nucleic acids - Genetic material - Genetic material Chemicals for life Living vs Non-living

6. Clarifying ?s Information Page 12 nucleic acids - genetic material - genetic material Summary: Stimulus - surroundings that cause the organism to react - surroundings that cause the organism to react Example: temperature, light, sound, gravity Response - the reaction of the organism to its surroundings - the reaction of the organism to its surroundings Example: movement, growth Spontaneous generation - the idea that living things come from non-living sources - the idea that living things come from non-living sources Example: Flies came from decaying meat. Francesco Redi proved this wrong in the 1600’s Living vs Non-living Reproduction - For life to continue organisms must produce offspring. - For life to continue organisms must produce offspring.
