while Gram-negative bacteria retain a dye that is _________ in color.
Purple, pink
Match each of the following terms with the correct description
Neutrophils
Lymphocytes
Monocytes
Eosinophils
Macrophages and dendritic cells are differentiated versions of this immune cell.
Characterized by grainy, multi-lobed nuclei.
Fight parasitic infections by releasing damaging enzymes.
Include NK cells, B cells, and T cells.
Neutrophils: Characterized by grainy, multi-lobed nuclei.
Lymphocytes: Include NK cells, B cells, and T cells.
Monocytes: Macrophages and dendritic cells are differentiated versions of this
immune cell.
Eosinophils: Fight parasitic infections by releasing damaging enzymes.

,Neutrophils
The most abundant type of phagocytic cell. Play a major role in the process of
inflammation. Have a characteristic grainy, multi-lobes (2-5) nuceli under a microscope.
Lymphocytes
Play roles in both innate and adaptive immune defenses and include natural killer cells
(NK cells), B cells, and T cells.
Monocytes
Naive, undifferentiated cells that will become Macrophages and dendritic cells, these are
the differentiated versions of this immune cell.
Macrophages
Phagocytic cells that may travel through the bloodstream patrolling or may permanently
be located in tissues throughout the body.
Dendritic Cells
Are similar to macrophages but exhibit higher specificity for pathogens and are classified
as both innate and adaptive cells. Reside in tissues to engulf pathogens.
Eosinophils
Are found in low concentration within the blood and in high concentration in
epithelial tissue. Fight parasitic infections by releasing damaging enzymes onto the
parasite. They also play a role in allergic and inflammatory responses.
Barrier defenses fall under the adaptive arm of the immune system
False: Barrier defenses fall under the innate arm of the immune system.

A) DNA is housed in a membrane-bound nucleus
B) They are always single celled
C) Bacteria are examples
D) All of the above statements are true
List the THREE common bacterial shapes
Cocci: Spherical-shaped, like a ball.
Bacilli: Rod-shaped.
Spiral: Spiral-shaped, ranging from comma-like to corkscrew-like.
Spherical-shaped cells arranged in chains can be best described by which of the following terms?
A. staphylococci
B. streptobacilli
C. streptococci
C. streptococci
staphylococci is clusters
List the two MAIN branches of immunity and compare them by response time.
Innate Immunity: rapid response
Adaptive Immunity: slower response
