In cymose type of inflorescence:
(1) Main axis continues to grow and the flowers are borne in acropetal succession.
(2) Main axis continues to grow and the flowers are borne in basipetal succession.
(3) Growth is limited and the flowers are borne in basipetal succession.
(4) Growth is limited and the flowers are borne in acropetal succession.
In racemose type of branching:
1. Branches continue to grow indefinitely and give off further branches laterally in a basipetal order
2. Branches continue to grow indefinitely and give off further branches laterally in an acropetal order
3. Branches stop growing after some time and give off further branches laterally in a basipetal order
4. Branches stop growing after some time and give off further branches laterally in an acropetal order

Which one of the following option is not correctly matched?
(1) cymose (2) Hypanthodium (3) Cyanthium (4) Verticillaster |
Acacia Banyan Euphorbia Calotropis |
Cymose inflorescence is identified by:
1. Basipetal arrangement of flowers on the main axis (peduncle)
2. The limited growth of the main axis as main axis terminates in a flower
3. Both (1) and (2)
4. Presence of sessile flower
Flower is
(1) Modified leaf
(2) Modified shoot
(3) Modified petiole
(4) Modified pedicel
Which of the following is a characteristic of flower?
(1) Internodes do not elongate
(2) Axis gets condensed
(3) Shoot apical meristem changes to floral meristem
(4) All of these
In Floral meristem
(1) Apex produces different kind of floral appendages
(2) These appendages are anterior
(3) Successive nodes have no leaves
(4) When a shoot tip transforms into a flower, it is always solitary
Find the odd one.
Inflorescence is
(1) Arrangement of leaves over stem
(2) Arrangement of flower over floral axis
(3) Arrangement of flower over pedicel
(4) Arrangement of leaves over nodes
