Answer 1

Does not take up the stain.

Step-by-step explanation:

Negative staining refers to the process wherein the unstained specimen is visualized under the darkly stained background.

One of the examples is capsule staining wherein the capsulated cells are stained with India ink or nigrosin dyes. The particles of these dyes stain the background blue-black but cannot enter the capsule.

Hence, the light-colored capsulated cells are visualized in the midst of the blue-black background.
