Question

The fruit of family umbelliferae is
A. Cremocarp
B. Carcerulus
C. Siliqua
D. Regma

Answer 1

Hint:- Fruit is defined as the mature ovary with or without seeds. In some fruits, other structures derived from other floral parts or receptacles may become the part of the fruit. It may consist of several mature ovaries remaining together as a unit.

Complete step-by-step solution:-Cremocarps- These are a type of schizocarpic or splitting fruit. The fruit breaks from below upwards into two single seeded, indehiscent segments called mericarps. The mericarps are attached to the tip of the central axis or carpophore. These fruits have generally oily seeds that contain large quantities of fatty oils. For example, fruits of coriander, fennel, etc. that belong to the umbelliferae family.
Carcerulus- This is also a type of schizocarpic fruit in which the fruit splits into many single seeded and indehiscent mericarps. For example, Ocimum and Althaea rosea.
Siliqua- It is a fruit that has fused carpels and their length is thrice of their width. The fruits of the cabbage family are silique type and they consist of narrow seed pods that split open when mature.
Regma- It is also a type of schizocarpic fruit in which the mature fruit breaks into one seeded dehiscent parts called cocci. For example, Castor fruit.
Additional information: There are mainly three types of fruits:
Simple fruits- These fruits develop from monocarpellary ovary or multicarpellary syncarpous ovary. These are of two types- fry fruits and succulent fruits.
Aggregate fruits- These fruits develop from the multicarpellary apocarpous ovary.
Composite fruits- These fruits develop from the complete inflorescence.
The correct answer is 1. cremocarp.

Note:-
Fruits develop from the ovary after fertilization in plants and they contain seeds that develop from ovules. The main function of the fruits is to protect the seeds in young and immature conditions.
