Cancer cell. Colored scanning electron micrograph (SEM) of a cell of a
cervical carcinoma. Carcinomas are cancers of the lining membranes of
organs. This cell shows an uneven surface and many cytoplasmic projections.
Clumps of cancerous cells form tumors which possess the ability to invade
and destroy surrounding tissues. Tumors can also travel to unrelated parts
of the body and give rise to secondary tumors. Malignant cells proliferate
and grow in a chaotic manner, with defective cell division retained within
each new generation of cells. Cancer of the cervix is one of the most common
cancers affecting women, and is often fatal. Magnification unknown.

Blood cells and platelets. Colored Scanning Electron micrograph (SEM) of
human blood showing red and white cells and platelets. Red blood cells
(erythrocytes) have a characteristic biconcave-disc shape and are numerous.
These large cells contain hemoglobin, a red pigment by which oxygen is
transported around the body. They are more numerous than white blood cells
(yellow). White blood cells (leukocytes) are rounded cells with microvilli
projections from the cell surface. Leucocytes play an important role in the
immune response of the body. Platelets are smaller cells (pink) that play a
major role in blood clotting.
