Plants are multicellular organisms composed of millions of plant cells. Although individual cells may differ greatly from each other in mature structure, all plant cells share the same basic eukaryotic organization. That is, each plant cell possesses a nucleus and cytoplasm with subcellular organelles. In addition to these components, all plant cells possess a cell wall of cellulose. Although plant cells begin their life with a full complement of cellular components, some specialized cell types lose their nuclei and all or part of their cytoplasm as they mature.
