Most cells share features such as having a nucleus, a cell membrane, cytoplasm and mitochondria. STEM CELL. Cell differentiation is an important process through which a single cell gradually evolves allowing for development that not only results in various organs and tissues being formed, but also a fully functional animal. This means they are modified by size, shape, or function according to their purpose. Notice that in figure A the guard cells are turgid, or swollen, and the stomatal opening is large. Functions of Organelles: Cytoplasm: It helps keep all of the things inside of the cell together.
