Where in a plant can new growth occur?

New growth in plants primarily occurs in regions called meristems, which are clusters of undifferentiated cells that have the potential to divide and differentiate into various types of plant tissues. The apical meristem, located at the tips of roots and stems, is responsible for the elongation and growth of these regions. This upward growth contributes to the increase in height of stems and the depth of roots. Additionally, lateral buds, which are found at the axils of leaves, can also produce new growth as they develop into new shoots or branches when conditions are favorable.

This understanding emphasizes the importance of the apical meristem and lateral buds in generating new growth. Other parts of the plant have different functions and roles in plant development, but they do not contribute directly to new growth in the same way as the meristematic regions do.
