You have been asked to do a strucutural study to understand how increasing cell surface area affects cell size, cell shape and functions. What cell type would help you most efficiently observe the effects of increasing surface area?  Choices:  A. Monocytes from the blood serum. Monocytes are largely roughly spherical cells.  B. Red Blood cells from the bone marrow. The shape of Red blood cells is a biconcave disk and looks like a donut. C. Stem cells from skin. In this case assume a skin stem cell is flat and plate like.  D. Microvilli covered cells from the intestines. Microvilli are tiny hair like protrusions in the plasma membrane of intestinal cells that increase the absorption of nutrients in the intestines.

Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.
