Cabuhat, LPT, M.Sc. cand. Spontaneous Generation Theory Spontaneous generation theory is an archaic scientific theory which stated that living organisms could arise from nonliving matter. Aristotle proposed that life arose from nonliving Aristotle (384–322 BC) material if the material contained pneuma (“vital heat”) Spontaneous Generation Theory Egyptians as supporters of the Spontaneous Generation Theory SOURCE: https://is.muni.cz/el/1431/podzim2014/JAG01/um/27521142/Scientific_Method_Roundness_of_the_Earth_2013_Ss.pdf Spontaneous Generation Theory Helmont as supporter of the Spontaneous Generation Theory Source: https://insertwisdom.files.wordpress.com/2016/04/mice-reipe.jpg?w=800 Scientific Method Spontaneous Generation Theory Redi disagree with the Spontaneous Generation Theory Francesco Redi Evidence against spontaneous generation theory Source: https://www.dreamstime.com/to-test-hypothesis-francesco-redi-placed-fresh-meat-open-containers-as-expected-rotting-mea t-accracted- flies-image178248315 Spontaneous Generation Theory A battle between Needham & Spallanzani on the Spontaneous Generation Theory With bacterial growth Broth in a flask What are the Without similarities and bacterial differences? growth Broth in a flask Source: https://www.timetoast.com/timelines/history-of-spontaneous-generation-713e3616-1603-4218-bb9d-a5e986726470 Spontaneous Generation Theory Pasteur disproved the spontaneous generation theory Louis Pasteur Spontaneous Generation Theory Among the given scientists, who disproved the Theory of Spontaneous Generation?

Microscope Cell structure 3 MAIN TENETS OF CELL THEORY 02 Cell is the basic and functional unit of all living things. All organisms are made up of one or more cells. Cells arise from other cells through cellular division – Rudolf Virchow. 08 Proponent of the 2nd tenet of cell theory Theodore Schwann All animals are made up of cell.

CRITERIA TO CONSIDER LIVING 11 For any entity to be considered alive, it must satisfy the three criteria: 1 Genetic Material 2 Plasma Membrane 3 Metabolic Machinery CRITERIA TO CONSIDER LIVING 11 Genetic Material The genetic material of all organisms is the double-stranded DNA. DNA - Deoxyribonucleic acid CRITERIA TO CONSIDER LIVING 12 Plasma Membrane Plasma membrane The plasma membrane is fluid- mosaic and is selectively permeable. CRITERIA TO CONSIDER LIVING 13 Metabolic Machinery Viruses use the host cell metabolic machinery to produce the proteins necessary for their replication (Slonczewski & Foster, 2013). 10 ASSIGNMENT Pair, Think, and Share Print and complete the activity that will be posted in Google Classroom.
