Microscope Setup and Cell Observations
Proper microscope setup and focusing technique for cell observation
| Magnification | Field of View | Detail Level | Best For |
|---|---|---|---|
| x40 (4x objective) | Large | Overview | Finding cells, general structure |
| x100 (10x objective) | Medium | Good detail | Cell shape, basic organelles |
| x400 (40x objective) | Small | High detail | Organelles, mitosis stages |
