Specialized cells are defined by having specific structures and functions that enable them to perform particular roles within an organism. This specialization arises from the differentiation process during development, where stem cells develop into distinct cell types. For example, a neuron has a unique structure designed for transmitting nerve signals, while a red blood cell is specialized for carrying oxygen. This specialization allows for efficiency and effectiveness in biological processes.

The other options do not accurately represent specialized cells. Cells that can easily change to other types refers to stem cells, which are undifferentiated and can give rise to different cell types, but they are not considered specialized. Identical cells in structure imply a lack of specialization, as one of the hallmarks of specialized cells is their distinct features. Lastly, while some specialized cells are found in embryonic stages, many specialized cells exist in fully developed organisms, making that option too limiting to define all specialized cells.
