Q. The increase in the length of stems and roots in plants is due to
A meristem is a tissue in plants made of dividing cells. They are in parts of the plant where growth can take place. Plant cells which are differentiated generally cannot divide or produce cells of a different type. Therefore, cell division in the meristem is necessary to get new cells. This allows for the growth of tissues and new organs needed by the plant.
- lateral meristem
- intercalary meristem
- apical meristem
- secondary growth
Answer: Apical Meristem
Due to the cell division in the shoot apical meristem, the increase in the length of stems and roots in plants happen.
The increase in length of the shoot and the root is referred to as primary growth, and is the result of cell division in the shoot apical meristem. Secondary growth is characterized by an increase in thickness or girth of the plant, and is caused by cell division in the lateral meristem.
The roots are anything below the ground and the shoots are anything above the ground. On a more technical level, the root system includes the roots (of course), tubers, and rhizomes. The shoot system includes leaves, buds, flowers, stems and fruits, if applicable.

The apical meristem, or growing tip, is found in the buds and growing tips of roots in plants. Apical meristems are very small, compared to the cylinder-shaped lateral meristems.
