Cell types are commonly classified based on their function, morphology, and origin. This classification helps in systematically studying and understanding the diversity and specialization of cells.
Function: Cells can be classified based on their roles, such as nerve cells (neurons) that transmit signals, muscle cells that aid in movement, and secretory cells that produce and release substances. Morphology: The shape and structure of cells also play a critical role in their classification. For example, squamous cells are flat and thin, while cuboidal cells are cube-shaped, and columnar cells are taller than they are wide. Origin: Cells can be traced back to their germ layer of origin during embryonic development—ectoderm, mesoderm, or endoderm.
