Question

Please describe what a monocyte looks like. Please include a description of the nucleus, the chromatin, the cytoplasm, and if there is the presence of granules.

a) Large, kidney-shaped nucleus, fine chromatin, abundant pale blue-gray cytoplasm, no granules
b) Small, round nucleus, coarse chromatin, scant light blue cytoplasm, granules present
c) Multilobed nucleus, fine chromatin, abundant pink cytoplasm, granules present
d) Biconcave nucleus, dense chromatin, scant pink cytoplasm, granules absent

Answer 1

A monocyte is a type of agranular leukocyte with a large, kidney-shaped nucleus, fine chromatin, and abundant pale blue-gray cytoplasm. Monocytes do not have granules in their cytoplasm. They differentiate into macrophages, which have phagocytic properties.

Step-by-step explanation:

A monocyte is a type of agranular leukocyte, which means it does not have visible granules in its cytoplasm. It has a large, kidney-shaped nucleus and fine chromatin. The cytoplasm of a monocyte is abundant and pale blue-gray in color. There are no granules present in the cytoplasm of a monocyte. Monocytes originate from myeloid stem cells and are typically 12-20 µm in size with an indented or horseshoe-shaped nucleus. They differentiate into macrophages, which are responsible for phagocytizing debris, foreign pathogens, and damaged cells.
