During magnification 40x, you can faintly see some organelles. Onion with Dye During magnification 4x, the iodine didn't make any difference in seeing the cells. During magnification 10x, you could almost see the organalles. During magnification 40x, you could see the tiny organalles and the nucleus,too. Light microscopes help you to see specimens up close.
Light microscopes use light to pass through the specimen to see it.
The magnifications 4x, 10x, and 40x help you to see the details of the specimen. The larger the magnification the better the detail. For example, I couldn't see much organelles in the onion with the iodine at 4x, but when the magnification became larger you could actually see them.
