       List -I                         List -II

(A) Polyembryony               (III) Orange 

(B) Parthenocarpy              (IV) Banana

(C) False Fruit                    (I) Apple

(D) Embryo Sac                 (II) Female gametophyte

(A) Polyembryony   (III) Orange
 Occurrence of more than one embryo in a seed is referred to as polyembryony. Example orange .

(B) Parthenocarpy  (IV) Banana

In most of the species, fruits are the results of fertilisation, there are a few species in which fruits develop without fertilisation. Such fruits are called parthenocarpic fruits. Banana is one such example .

(C) False Fruit  (I) Apple

In most plants, by the time the fruit develops from the ovary, other floral parts degenerate and fall off. However, in a few species such as apple, strawberry, cashew, etc., the thalamus also contributes to fruit formation. Such fruits are called false fruits. Most fruits however develop only from the ovary and are called true fruits.

(D) Embryo Sac  (II) Female gametophyte

Enclosed within the integuments is a mass of cells called the nucellus. Cells of the nucellus have abundant reserve food materials. Located in the nucellus is the embryo sac or female gametophyte. An ovule generally has a single embryo sac formed from a megaspore.
