Primary Growth in Plants
- The region at the plant’s apex is known as the apical meristem. It aids in the plant’s ability to grow taller.
- Lateral meristem: Because of the lateral meristem, the stem and roots’ diameters grow. It can be found on both the stem and the roots.
- Some plants have an intercalary meristem, which is situated close to the nodes. It promotes the expansion of internodes and leaves.
- The apical meristem extends the length of stems and roots by being present at their developing terminals.
Summary:
Primary growth in plants occurs by (a) Vertical meristem (b) Lateral meristem (c) Intercalary meristem (d) Apical meristem
Intercalary meristem and Apical meristem helps in Primary growth in plants. Intercalary meristem can be found in the leaves and nodes. Their main objective is to enlarge and grow the parts of the plants.
