Question

In ________ type of inflorescence, main axis terminates in a flower, hence is limited in growth and flowers are born in _________ succession.

• A. racemose, acropetal
• B. racemose, basipetal
• C. cymose, acropetal
• D. cymose, basipetal

Answer 1

The correct option is D cymose, basipetal

• Depending on whether the apex gets developed into a flower or continues to grow, two major types of inflorescences are defined – racemose and cymose.
• Acropetal and basipetal are two terms used to describe different arrangements of florets in the inflorescence. The older parts are at the bottom in the acropetal arrangement while the older parts are on the top in the basipetal arrangement.

In cymose type of inflorescence the main axis terminates in a flower, hence is limited in growth. The flowers are borne in a basipetal order.
In racemose type of inflorescences the main axis continues to grow, the flowers are borne laterally in an acropetal succession.
