All cells and many subcellular structures are surrounded by a membrane. Assuming a typical membrane to be about 8 nm wide, how many such membranes would have to be aligned side by side before the structure could be seen with the light microscope

25 membranes

Explanation:

A light microscope makes it possible for the scientist to view and visualize structures with a minimum of 200 nm in diameter. So, if a typical membrane is about 8 nm wide, then we can divide the minimum diameter with the given width of the typical membrane to determine the number of membranes.

SO;

= 25 membranes

So, in a light microscope, there are about 25 membranes that will align side by side to view the structure.
