Concept: This question tests your understanding of different types of inflorescence, specifically focusing on the characteristics of cymose inflorescence.

Why (D) is correct:

• In cymose inflorescence, the main axis terminates in a flower, which stops its further growth.
• Subsequent flowers develop laterally below the terminal flower. This results in flowers being borne in a basipetal order, meaning the older flowers are at the top (center) and younger flowers are towards the base (periphery).
• Therefore, both statements (A) and (B) accurately describe cymose inflorescence.

Why other options are wrong:

• (A) flowers are borne in a basipetal order: This is correct for cymose, but not the complete description.
• (B) the main axis terminates in a flower: This is correct for cymose, but not the complete description.
• (C) flowers are born laterally in an acropetal succession: This describes racemose inflorescence, where the main axis continues to grow, and younger flowers are at the apex (acropetal succession).

NEET Tip: Remember the key difference: Cymose = Closes (main axis terminates), Basipetal. Racemose = Remains open (main axis continues to grow), Acropetal.

Correct Answer: (D)
