A tissue component that takes up a cationic dye is said to be which of the following?

Explanation:
Basophilic describes tissue components that take up basic (cationic) dyes. These dyes, like hematoxylin, carry a positive charge and are attracted to negatively charged structures such as DNA and RNA in the nucleus (and ribosomes). Because of this attraction, basophilic elements stain blue-purple in typical stains. In contrast, eosinophilic (acidic) dyes bind to positively charged components like cytoplasmic proteins and stain pink/red. The term neutral isn’t used to describe uptake of cationic dyes.
