The highest power objective is 40x, with a resolution of 420 nm using a wavelength of 546 nm.
The majority of eukaryotic cells are on the order of 10-100 micrometers in diameter. Bacterial cells are smaller, typically between 1-10 micrometers. The nuclei, chloroplast, and mitochondria or eukaryotic cells are similar in size to bacteria with most mitochondria ~1 micrometer in diameter, the size of a small bacteria. Ribosomes are only about 30 nm. So....
Which of the eukaryotic organelles should be able to see clearly with the hightest power objective of your microscope and why?
