1. What is the Difference between an Hypothesis and a Theory? Hypothesis –Statement based on extemporaneous information and testable data. Invitro – done or executed outside of the living organism Invivo – occurs inside of the living organism Scientific Theory –an hypothesis that is supported by a large body of evidence and is the best explanation that scientists agree upon

2. What is the Cell Theory? Cell Theory: All living organisms are composed of cells, and the products of cells Cells are the smallest units of life Cells only come from pre-existing cells

3. Evidence of Cell Theory: All life is either unicellular or multicellular Cells → Tissues → Organs → Organ Systems → Organism → Community Phagocytosis of Mitochondria 1. Mitochondria were once small prokaryotic cell 2. Mitochondria was phagocytized by larger prokaryotic cell 3. Larger prokaryotic cell replicated, producing new cells with mitochondria in cytoplasm

4. Endocytosis: Phagocytosis – Cell Eating Pinocytosis – Cell Drinking Vesicle Invagination

5. Prokaryotes vs. Eukaryotes
