Question
Chapter 5, Problem 2.2A
Summary Introduction
To analyze:
The advantages of staining cells.
Introduction:
Staining is the technique in biology, which increases the visibility at the microscopic level. Dyes and stains are commonly used by the biologist for certain observations. The dye is used for the general-purpose, whereas the stain is used for biological purposes.
