Two dry fruits (A & B) were observed. Both developed from unilocular ovaries of monocarpellary gynoecia. In fruit. A, pericarp and seed coat are free. It liberated the seeds only after the disintegration of the pericarp. Fruit ‘B’ dehisced dorsiventrally librating the seeds. In the following, the former in the pair represents ‘A’ and latter ‘B’. to which types of fruits ‘A’ and ‘B’ respectively belong? |

|
a) |
Achene and legume |
b) |
Nut and follicle |
|
c) |
Cypsella and siliqua |
d) |
Pyxidium and septicidal capsule |

(a) Achene develops from monocarpellary unilocular ovary but the fruit wall (pericarp) is not fused with seed coat, e.g., rose, Mirabilis, Clematis. Legume developed from monocarpellary, unilocular superior ovary with marginal placentation, e.g., family-Leguminosae. |
