B. phagocytic material.

C. fatty acids.

D. hormones.

E. lysosomes.

5. Which cells produce antibodies to fight off infections in the organism?

A. Lymphoblasts

B. Plasma cells

C. Eosinophils

D. Basophils

E. Pluropotential cells of bone marrow

ANSWERS

1. Correct answer: C. The pyknotic nucleus is extruded. In order to increase
the area of the cytoplasm for gas-carrying capacity, the developing
erythrocytes extrude their nuclei and enter the circulation.

2. Correct answer: A. Accumulation of specific granules in their cytoplasm.

The accumulation of different granules in the cytoplasm of the myelocytes
allows identification of differentiating myelocytes.

3. Correct answer: B. Eosinophils. These cells have affinity for and
phagocytize the antigen–antibody complexes.

4. Correct answer: E. Lysosomes. With electron microscopic examination,
the cytoplasm of neutrophils contains granules that have been shown to

contain lysosomes.

5. Correct answer: B. Plasma cells. B lymphocytes differentiate into plasma
cells when exposed to antigens, after which they produce antibodies to
counteract invading or infectious organisms.
