Hello, I figured your question was missing its answers so I went online to find them. Here they are:
No visible cytoplasmic granules are present in ________.
A) basophils
B) monocytes
C) eosinophils
D) neutrophils
Answer:
The correct answer is: B) monocytes.
Explanation:
<u>White blood cells can be divided into granular and agranular.</u> Granular leukocytes (WBC) have granules that contain enzymes in their cytoplasm (the enzymes are used in the immune and inflammatory responses). <u>Agranular leukocytes</u><u> do not have cytoplasmic granules</u>.
<u>The granular leukocytes are 3: basophils, eosinophils, and neutrophils</u>.
<u>The</u><u> agranular</u><u> leukocytes are: </u><u>monocytes</u><u> and lymphocytes</u>.
Monocytes are very large cells with the important function of phagocytosis: this makes them capable of eating pathogens and old blood cells. When arriving at a tissue outside of the blood, they differentiate to macrophages with special features to perform in that tissue. They make up <u>2 to 8 percent of all leukocytes</u>. Monocytes and macrophages are also antigen-presenting cells (APCs): when needed, they can present antigens to other white blood cells in order to mediate the immune response.
