11.4 Cell Cycle Control during Development

In contrast to animals, plants can continue to form new organs and tissues throughout their life span. They can do this because they have regions of localized cell division known as meristems, which are origins of tissues and organs and also replenish the stock of dividing cells. Cells in meristems are sometimes called ‘stem cells’, terminology that has been imported from a highly active area of current biomedical research. The term refers to the ability of these cells to go through numerous cycles of mitosis and remain undifferentiated while still retaining the potential to differentiate into a specialized cell type. Because of the scope for confusion over the precise meaning of ‘stem cells’ in the context of plant development, we will not use the term in this book.
