Three types of cells are found suspended in the plasma of blood. They are: erythrocytes (RBC), leukocytes (WBC) and thrombocytes (Platelets). Erythrocytes (red blood corpuscles) are spherical or oval cells that are responsible for the oxygen carrying capacity of blood. The RBC a..

The history of the discovery of cells dates back to the 17 t h century and is closely associated with the history of the invention of microscopes. An Italian microscopist Marcello Malpighi studied the structure of some plants and proposed the idea that plants are compo..

Cells vary in shape and size. They may be oval, spherical, rectangular, polygonal, spindle shaped, star shaped, rod-shaped or totally irregular like the nerve cell. The diversity in cells is in accordance with the role or function it has to perform as part of the tissu..
