NEETBotanyPlant - Growth and Development
Choose the correct statement regarding the phenomenon described in the diagram.
Options
- AIn most higher plants, the growing axillary bud inhibits the growth of the apical bud.
- BDecapitation of shoot tips is done to inhibit this phenomenon.
- CInhibition of this phenomenon results in growth of apical buds
- DThis phenomenon is mostly seen in lower plants.
Correct answer
B. Decapitation of shoot tips is done to inhibit this phenomenon.
Step-by-step solution
In most higher plants, the growing apical bud inhibits the growth of the lateral (axillary) buds, a phenomenon called apical dominance. Removal of shoot tips (decapitation) usually results in the growth of lateral buds. In [A] it's written the growing axillary buds whereas growing apical buds inhibit growth of axillary bud. In[C] inhibition of apical dominance results in growth of lateral buds not apical buds. In [D] This phenomenon is mostly seen in higher plants not lower plants.
