Wavelengths of light - Study guides, Class notes & Summaries

all organisms are made of cells and come from cells Cell theory When the cell size (INCREASES or DECREASES), the membrane gets smaller compared to cell volume. increases the study of cells Cytology "how can cork float" Took sections, looked under microscope and found that they had tiny chambers (aka cells) Robert Hooke Part of electromagnetic spectrum via sun, delivering energy that can be recorded as wavelengths (convert into color - ROY G BIV: red, orange, yellow, green, blue, indig...
