Cell Theory and Structure: historical walk and formal definition

Section role: supports the formalization of cell theory and structure in Section 3 while the teacher transitions from student microscope sketches to definitions. Slides: (1) Title — 'Unveiling Cell Theory and Structure'; (2) Historical Pioneers — bullets: Robert Hooke naming 'cells' from cork, Anton van Leeuwenhoek seeing 'animalcules'; (3) The Three Tenets — bullets: all organisms are made of cells, cells are the basic unit of life, all cells come from pre-existing cells; (4) Prokaryote vs. Eukaryote — bullets: defining the nucleus as a storage room for DNA, comparing bacteria to plant and animal cells; (5) Plant vs. Animal Cells — bullets: recalling the onion skin and cheek cells from the explore phase, introducing the cell wall and chloroplasts; (6) The Virus Exception — bullets: discussing why viruses possess genetic material but lack cellular structure; (7) Summary Mind Map — visual link connecting cell types and theory. Closing slide: 'How does knowing that all cells come from pre-existing cells help us understand growth and healing?' — sets up the transition to biological hierarchy in Section 4.
