Cell Theory

Cells are the basic structural and functional units of all known living organisms and arise from pre-existing cells.

Simplest Living System

Cells represent the simplest level of organization capable of independent life.

Leukocytes

Leukocytes are white blood cells, which are divided into granulocytes and agranulocytes based on the presence of granules in their cytoplasm.
