2. What are the 6 steps of the Scientific Method
What are the 6 steps of the Scientific Method? Identify problem, Research, Hypothesis, Test / Experiment, Record & Analyze, Conclusion
What is the information gathered from making observations? data
6 Common Characteristics: cells, DNA, use Energy, respond to change, reproduce, grow & develop.

3. Response – reaction to a change in environment Stimulus – a change in environment
Homeostasis – ability to maintain stable internal conditions.
Growth: getting larger Develop: become more complex

4. Smallest unit of life: Cell
Scientist 1st discovered cells: Robert Hooke
Scientist discovered “animalcules”: Anton von Leeuwenhoek
Are all bacteria harmful? No

5. 11. Cell Theory: All organisms are made of cells
11. Cell Theory: All organisms are made of cells. The cell is the basic unit of life. All cells come from other cells. 12. Spontaneous Generation: When cells form from non-living things. Not true. 13. Prokaryotic cell: no nucleus, all unicellular Eukaryotic cell: has a nucleus, mostly multicellular. Both: have DNA, cell membrane

6. Bacteria P; Plants E; Animals E; Fungi E; Protists E
15. Unicellular: one-celled
Multicellular: many cells
16. Only 2 Prokaryotes: bacteria and archaea
a. Cell Wall: shape & support for plant cells
b. Cell membrane: boundary of all cells; controls what goes in & out of cell.

7. Ribsomes: makes protein
Nucleus: controls cell activities; contains DNA
ER: transports material
Mitochondria: releases energy from food
Chloroplast: uses sun’s energy to make food for plants
Vesicles: moves material in & out of cell
Golgi bodies: processes & packages material
Lysosomes: breaks down waste, old cell parts
Vacuoles: stores water, food, waste
Cytoplasm: jelly-like fluid in cells

8. Organelles in plants only: cell wall, chloroplasts
Multicellular benefits: longer life, larger size, specialization
Specialization: different types of cells do different jobs for the organism
levels of organization: cell, tissue, organ, organ system, (organism)
