“The meristem is a group of undifferentiated cells at one of the top growing points of the plant that have not yet developed a vascular connection to the rest of the plant,” Schneider said. Meristem culture: Can be used repeatedly to eliminate viral and other infections.

The miniature pot plant has a pair of meristems: one at the top that will become the first growing tip ('shoot apical meristem') and one at the tip of the root ('root apical meristem') which will become the taproot. Meristem cells can divide to make more meristem cells, resulting in plant growth.
