ROBERT HOOKE 1st to see cells Cork Cells Cork cells. Are they living? Which cell part are we seeing here? Hookes’ actual sketch of cork Cells done in 1653 CELL THEORY • ALL living things are made of 1 or more cells • CELLS come only from other living cells • A CELL is the basic unit of structure and function in all living things A THEORY • Is NOT an educated Guess. A THEORY • * Explains many observations • * Is Testable • * Could be disproven • * Allows us to make accurate predictions Find: Mitochondria, endoplasmic reticulum, ribosomes CHLOROPLASTS Chloroplasts. Where photosynthesis happens Large central vacuoles in plant cells Golgi Complex Photo: Golgi complex pinching off vesicles full of proteins. Photo of a golgi complex Golgi 3D View Bacteria Cell Cells have an internal skeleton An Onion Cell Nucleus absorbs iodine and stains darker than the cytoplasm Fluorescent stain makes nucleus glow Blue Another color stain. Nuclei are dark red Cancer Cells often have more than 1 nucleus Cancer cell with several nuclei Evidence of cancer ? Is There evidence of cancer?
