NEETBotanySexual Reproduction in Flowering Plants
According to the morphological concept that a flower is a modified shoot, the shoot apical meristem changes to a floral meristem upon floral induction. What is the inevitable morphological consequence when the main shoot tip itself transforms into a flower?
Options
- AIt results in the formation of a racemose inflorescence.
- BThe resulting flower is always solitary.
- CThe floral axis continues to elongate indefinitely after flower formation.
- DIt leads to the exclusive production of axillary flowers.
Correct answer
B. The resulting flower is always solitary.
Step-by-step solution
A flower is a modified shoot wherein the shoot apical meristem changes to a floral meristem. When the main shoot tip itself transforms into a flower, the apical meristem is consumed in the formation of the floral parts. This terminates the growth of that specific axis (determinate growth). As explicitly stated in NCERT, when a shoot tip transforms into a flower, it is always solitary. It cannot form a racemose inflorescence because the main axis does not continue to grow indefinitely. It also does not refer to axil
