- ACollenchyma
- BEndodermis
- CCortex
- DApical meristem
Explanation
The apical meristems — located at the tips of roots (root apical meristem) and shoots (shoot apical meristem) — are the regions of active cell division responsible for primary growth in length of roots and shoots. Collenchyma, endodermis and cortex are differentiated tissues, not growth regions. Hence the apical meristem is responsible.
