Column I Column II.
A. Parthenocarpy I. Inactive state
B. Polyembryony II. Meiosis and syngamy are absent
C. Apomixis III. Occurrence of more than one embryo
D. Dormancy IV. Seedless fruit

 

Options:

A – III; B – II; C – I; D – IV

A – IV; B – I; C – II; D – III

A – IV; B – III; C – II; D – I

A – I; B – II; C – III; D – IV

Correct Answer:

A – IV; B – III; C – II; D – I

Explanation:

The correct answer is Option (3)-A – IV; B – III; C – II; D – I

Column I Column II.
A. Parthenocarpy IV. Seedless fruit
B. Polyembryony III. Occurrence of more than one embryo
C. Apomixis II. Meiosis and syngamy are absent
D. Dormancy I. Inactive state

Explanation:

A. Parthenocarpy refers to the development of fruit without fertilization. It leads to the formation of seedless fruits.

B. Polyembryony: In some species each ovule contains many embryos. Occurrence of more than one embryo in a seed is referred to as polyembryony.

C. Apomixis is a mode of reproduction where seeds are produced without the process of meiosis and syngamy. It leads to the development of embryos without fertilization.

D. Dormancy refers to a period of inactivity or suspended growth in seeds. Seeds undergo dormancy to survive adverse conditions and ensure germination occurs under suitable environmental conditions.
