(1) All flowering plants have the same type of inflorescence.
(2) Flowers always arise from the apical bud only.
(3) Flowers may arise from the axillary buds or terminal buds.
(4) Flowers may reach at the same level making a cluster.
Which of the above statements about inflorescence are incorrect ?
- (1) and (2)
- (2) and (3)
- (3) and (4)
- (1) and (4)
Answer
(1) and (2)
Reason — Flowering plants have different types of inflorescence. Flowers do not always arise from the apical bud; they can also arise from axillary buds.
Flowers may arise from the axillary buds or terminal buds depending on the plant type. Flowers appear at almost the same height forming a cluster.
