All plant cells are characterized by several common features, such as chloroplasts, a cell wall, and a large vacuole. These features also differentiate plant cells from animal cells. In addition, there is a number of specialized types of plant cells that are found only in vascular plants.ll plant cells are characterized by several common features, such as chloroplasts, a cell wall, and a large vacuole.
