Growth regions
- Typical growth regions in plants are the apices of shoots and root
- Such growing regions are known as apical meristems, primary meristems or regions of primary growth
- These apical meristems are responsible for the increase in length, differentiation of various appendages and formation of plant tissues
Â
Types of Growth
- The growth may be of two types:
a. Limited growth: The organs like leaves , flowers, and fruits have limited growth. These do not possess meristem
b. Unlimited growth: The organs like stem and roots have unlimited growth. These possess meristem
