All of the cells mentioned in the options possess a relatively high level of mitotic activity. Stem cells in various adult tissues and at the base of numerous epithelia undergo frequent mitosis to replace the damaged or dead cells. Hematopoietic stem cells in the bone marrow give rise to red and white blood cells, which have relatively short lifespans, thereby necessitating a high level of mitotic activity. The relatively unspecialized cells found near the tips of plant roots and stems are called meristematic cells, which divide frequently to support plant growth and development.
