Comparative biology: visual walkthrough of support systems

Section role: supports the 'Mapping the Systems of Support' section while the teacher explains endoskeletons, exoskeletons, and vascular stems. Slides: (1) Title — 'Skeletons Inside and Out'; (2) Endoskeleton — bullets: definition of internal bones, human and dog examples, growth alongside the organism; (3) Exoskeleton — bullets: external armor made of chitin, crab and beetle examples, protection vs growth limits; (4) Plant Stems — image of a vascular stem cross-section, bullets: bundle of straws analogy, water pressure and rigid cell walls; (5) Side-by-Side Comparison — crab vs dog visual comparing where the structure is located; (6) Debunking the Myth — plants do not have bones, but they do have support structures. Closing slide: 'Which type of support structure would be hardest to live with, and why?' — hands control back to the teacher for discussion.
