Updated On: Jul 18, 2026
- Hyphanthodium of ficus has irregularly arranged flowers
- Head inflorescence of sunflower has centrifugally arranged flowers
- Racemose inflorescence of Crotalaria has its flowers arranged in acropetal order
- Cymose of Jasmin has basipetally arranged flowers
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding inflorescence patterns.
Inflorescence refers to the arrangement of flowers on a plant axis. Different types show specific patterns like racemose (acropetal), cymose (basipetal), and special types like hypanthodium. Correct identification of these patterns is essential to evaluate statements.
Step 2: Understanding Ficus (Hypanthodium).
In Ficus, the inflorescence is called hypanthodium, where flowers are enclosed within a hollow receptacle. The flowers are not randomly arranged but are systematically placed on the inner wall, making the statement about irregular arrangement incorrect in strict botanical terms.
Step 3: Understanding sunflower inflorescence.
Sunflower has a capitulum (head inflorescence). In this, the floral arrangement follows a centripetal pattern, meaning older flowers are present at the periphery and younger ones towards the center. Therefore, it is not centrifugally arranged, making this statement incorrect.
Step 4: Understanding Crotalaria and Jasmine.
Crotalaria shows racemose inflorescence with acropetal succession, where younger flowers are at the top and older ones at the base. Jasmine shows cymose inflorescence with basipetal succession, where younger flowers are at the base. Both statements are correct biologically.
Step 5: Comparative elimination.
By comparing all statements, options (3) and (4) are correct descriptions of inflorescence patterns, while option (2) contradicts the known centripetal pattern of sunflower head inflorescence. Hence it is the most clearly incorrect statement.
Step 6: Final conclusion.
Thus, the incorrect statement is option (2).
