Diagram of Lateral Meristem

Lateral Meristem Diagram

  • A group of undifferentiated cells that is capable of continued cell division is referred to as meristematic tissue.
  • These cells are totipotent in nature that can divide until the time they finally differentiate and cannot divide further.
  • Meristematic cells can give rise to new organs and help in building the basic structure of the plant.
  • A meristematic tissue is of three types – apical meristem (found at the tips), intercalary meristem (found in the middle) and lateral meristems (found in the sides).
  • Examples of lateral meristems in the plant include vascular cambium and phellogen.
  • They are commonly found in gymnosperms and dicot plants and show secondary growth. They are not found in monocots as they do not show secondary growth.
  • The meristematic cells are small in size and are packed closely with no intercellular spaces.
  • There are small or no vacuoles present in the cells and it is completely filled with protoplasm.
