?
By how many times can a light (optical) microscope magnify an image?
It can magnify by 1500 times, which is enough to be able to see individual Eukaryotic cells and the organelles inside them.

What are the different parts and functions of these parts on a microscope?
1. Eyepiece (Look down.) 2. Coarse adjustment knob (Roughly focus.) 3. Fine adjustment knob (Fine-tune focus the specimen.) 4. High and low power objective lenses (Magnify the specimen.) 5. Stage (To put the slide on.) 6. Light (To see the specimen.)

By how many times can an Electron Microscope magnify an image by, and what benefits does this have for scientists?
An Electron Microscope can magnify an image by 500,000 times (498500 more than a light microscope), which allows for greater details to be seen, such as the structures in the cells organelles.
