This type of experiment showed that most marked cells divide just a few times and make a small contribution to growth of the plant, while a few cells within the meristems divide many times and ...

Plants form new leaves, flowers and roots at the tips of shoots and roots, in specific growth regions known as meristems. These meristems contain stem cells that divide as needed and form new ...

Plants are made up of organs (root, stem, leaf, and flower); organs consist of tissues (meristems, conducting, photosynthetic, structural); and tissues are made up of cells. Plant cells contain ...

Plants have stem cells too. They're found at the meristems, the growing tips of the roots and the shoots. The big difference is that the stem cells in adult plants can still make every type of ...
