What is the difference between simple stains and differential stains
Simple make bacteria stand out from background. Differential distinguish different types of bacteria
Acidic
Chromophore has a negative charge
Basic
Chromophore has a positive charge
Positive stain
Cells are stained
Negative stain
Background is stained, cells appear clear
Simple stain uses how many dyes
Only one dye
Differential stain uses how many dyes
Multiple dyes can be used to differentiate organisms
Purpose of a gram stain
Differentiate between bacteria with different types of cell walls
Purpose of an acid fast stain
Differentiate between two types of gram positive cells. Those with waxy mycolic acids and those that do not
Purpose of capsule stains
Used to distinguish cells with capsules vs those without
Purpose of a flagella stain
Used to view and study flagella in bacteria that have them
Purpose of an endospore stain
To distinguish organisms with endospores from those without

First to use term “cells” in 1965
Contributions of Schwann
Cells are the fundamental components of plants and animals
Contributions of Schleiden
Cells formed through crystallization rather than division
Contributions of Remak
Cells are derived from other cells as a result of cell division
Contributions of Virchow
