Strawberry and apple are classed as accessory fruits because they develop from what?
AFrom the ovary wall alone after fertilisation
BFrom a part of the flower other than the ovary
CFrom several carpels within one single flower
DFrom a cluster of flowers fused into one mass
Answer & Solution
Correct answer: B. From a part of the flower other than the ovary
1. Fruits that develop from the ovary are true fruits.
2. Accessory fruits, sometimes called false fruits, are not derived from the ovary but from another part of the flower.
3. In the strawberry that part is the receptacle, and in apples and pears it is the hypanthium.
4. Development from several carpels in one flower describes an aggregate fruit such as the raspberry.
5. Development from a cluster of flowers describes a multiple fruit such as the pineapple.
