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.

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

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

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

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.

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

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 21. 4 levels of organization: cell, tissue, organ, organ system, (organism)
