Stem cells differentiate into specialized cells through gene expression, influenced by internal and external cues. Learn about cell differentiation for your igcse biology exam. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.

The revision note includes a video, diagrams and named examples of differentiated cells. Stem cells are simple, unspecialised cells found in animals and plants that have the ability to divide to form cells of the same type. These structures include the cytoplasm, cell membrane, nucleus and mitochondria.
Specialised cells in animals have shapes, sizes and structures that are.
To develop into a nerve cell the cytoplasm and cell membrane of an undifferentiated cell must elongate to form. Cell differentiation is the process by which an immature cell develops into a specialized cell type with a distinct structure and function. They can also differentiate into a variety of specialised cells. Cells specialise by undergoing a process known as differentiation e.g.
Asymmetric segregation of cellular determinants and inductive signaling guide. The main difference between differentiated and undifferentiated cells is that differentiated cells are specialized to perform a unique function in the body whereas undifferentiated cells are. Stem cells are divided into several categories. Each structure has a specific function.
