Can you observe a large no. of cells under the 45X or 10X objective lens of a compound microscope? Explain?

Answer 1

You need to take in account that the eye-piece adds another 10X magnification. So , if you use the 10X objective, then, you are looking at something 100X its normal size. 450X if you use the 45X objective. So, If you use the 10X objective you will see more cells than the 45X because the magnification isn't as great. Use 10X to scan the slide, you see more cells this way. Then use 45X to focus in once you find what you are looking for. Anyways, well, the answer to your question; yes, you can look at a large number of cells using the 10X.

Answer 2

I think you're asking which objective lens will let you see a LARGER number of cells.

You see a larger number of cells under lower magnification, 10x (times the eyepiece lens) in your question. The field of view includes more cells than 45x, and the cells all appear smaller.

Answer 3

You can observe a large number of cells with no microscope at all. Just look at any nearby human being. It's a lump of trillions of cells.

The trick is observing a SMALL number of cells. That's much harder. A typical cell might be 5 micrometers (5 * 10^-6 meters) across. If you magnified this 45 times, it would appear to be about 0.2 millimeters across. This might be barely visible, but you probably wouldn't see any detail. A microscope capable of 300x magnification would be better suited to the task.

Answer 4

sure. I'm assuming you mean animal and plant cells.
I do it all the time.
