Question

josey wants to look at the cells of an onion under a light microscope. she peels off a thin, transparent layer of onion and places it on a microscope slide. josey places the sample on the microscope stage, looks through the eyepiece, and adjusts the stage to focus the image. however, she is unable to see any details of the cells. which of the following possible solutions could possibly help josey to see the onion cells in detail? a. josey should use a thicker piece of onion for her sample. b. josey should place her onion sample in a vacuum. c. josey should place a drop of water on her sample.

Explanation:

A thicker sample may block light and not help with visibility. Placing in a vacuum is unnecessary for light - microscopy of onion cells. Placing a drop of water on the sample can help flatten the cells, reduce air - gaps, and improve light transmission for better visibility under the light microscope.

Answer:

C. Josey should place a drop of water on her sample.
