(a) Racemose and cymose inflorescence
(b) Fibrous root and adventitious root
(c) Apocarpous and syncarpous ovary
Solution:
The differences are as follows:
(a) Racemose and cymose inflorescence
| Racemose inflorescence | Cymose inflorescence |
| Young flowers are at the tip of the inflorescence, while older flowers are arranged at the base. | Old blooms are at the tip of the inflorescence, while new flowers are arranged towards the base. |
| Laterally, the main axis continues to expand and produce blooms. | The main axis has limited growth which terminates into flower. |
(b) Fibrous root and adventitious root
| Fibrous roots | Adventitious roots |
| In monocotyledons, the primary root is short-lived and is replaced by a vast number of roots. | Various than the radicle, roots grow from other sections of the plant. |
| Example: Wheat | Example: Banyan tree |
(c) Apocarpous and syncarpous ovary
| Apocarpous ovary | Syncarpous ovary |
| In apocarpous ovary, two or more carpels are free | In syncarpous ovary, two or more carpels are fused |
| Example: Lotus | Example : mustard |
