Questions with solutions
Q1 — The Inflorescence · easy · theory
An inflorescence in which the main axis continues to grow and flowers are borne laterally in acropetal succession is:
A. Cymose
B. Solitary
C. Racemose ✓ Correct
D. Cyathium
Solution: In racemose inflorescence the main axis keeps growing and older flowers are at the base (acropetal).
Q2 — The Inflorescence · easy · theory
In a cymose inflorescence, the main axis:
A. Grows indefinitely
B. Never bears flowers
C. Bears flowers in acropetal order
D. Terminates in a flower and has limited growth ✓ Correct
Solution: In cymose inflorescence the main axis ends in a flower (basipetal order); growth is limited.
Q3 — The Inflorescence · medium · theory
The capitulum (head) inflorescence, as in sunflower/Asteraceae, consists of:
A. A single terminal flower
B. Sessile florets crowded on a flattened receptacle ✓ Correct
C. A branched cyme
D. Flowers on long pedicels
Solution: The capitulum bears numerous sessile florets (ray + disc) on a broad receptacle — a racemose type.
Q4 — The Inflorescence · medium · theory
Acropetal succession of flowers means the:
A. Youngest flowers are at the base
B. All flowers open together
C. Youngest flowers are near the tip and oldest near the base ✓ Correct
D. Flowers open from tip to base
Solution: Acropetal (racemose): oldest at base, youngest at apex — opposite to the basipetal cymose pattern.
Q5 — The Inflorescence · hard · theory
The specialised cyathium inflorescence (Euphorbia) mimics a single flower and contains:
A. A single male flower
B. Many male flowers (each a single stamen) around one female flower ✓ Correct
C. Ray and disc florets
D. Only bisexual flowers
Solution: The cyathium has a cup-shaped involucre enclosing many reduced male flowers and one central female flower.
Q6 — The Inflorescence · hard · theory
Which correctly distinguishes racemose from cymose inflorescence?
A. Cymose — indefinite axis, acropetal
B. Racemose — main axis ends in a flower
C. Both have unlimited growth
D. Racemose — indefinite main axis, acropetal; Cymose — main axis ends in a flower, basipetal ✓ Correct
Solution: The key distinction is the fate of the main axis and the direction of flower opening.
