Where is Primary Growth Occurring in an Old Tree

Question

Where is primary growth occurring in an old tree?
A) closest to ground level at the base of the tree
B) where the vascular cambium and cork cambium are
C) in young branches where leaves are forming
D) nowhere; trees have only secondary growth

Accepted Answer

Primary growth in plants, including trees, occurs at the tips of roots and shoots, leading to an increase in length. This growth is facilitated by the apical meristems, which are found in areas such as young branches where leaves are forming.
