Question

the diagrams below show four different one - celled organisms (shaded) in the field of view of the same microscope using different magnifications. which illustration shows the largest one - celled organism? 1 100x 2 400x 3 100x 4

Explanation:

Step1: Understand microscope magnification

Higher magnification makes the organism appear larger in the field of view. But when comparing at the same magnification, a larger - sized organism in the field of view (for the same magnification) is actually larger.

Step2: Compare magnifications and organism sizes

Illustrations 1 and 3 have a magnification of \(100\times\). Illustrations 2 has a magnification of \(400\times\). At \(100\times\) magnification, if we compare 1 and 3, the organism in 3 is larger in the field of view. Since 1 and 3 are at the same magnification (\(100\times\)), the larger - appearing organism (3) at this magnification is the larger actual organism.
