Question

Which of the following is false fruit –
A. Mango
B. Apple
C. Banana
D. Jackfruit

Answer 1

Hint: A fruit is said to be true fruit if it develops solely from the mature and ripened ovary after fertilization. It is also known as eucarp.

Complete answer:
False fruit is also known as accessory fruit, spurious fruit, pseudofruit, or pseudocarp. A false fruit is a fruit in which some of its flesh is derived not from the floral ovary but from some other tissue located exterior to the carpel i.e. some other reproductive part of the flower. Example- apple, pear, pineapple, strawberry, etc. Apple is formed from the thalamus and not from the ovary. So, it is known as false fruit.

Additional Information: Additional information: The seeds of true fruits develop from the ovules inside the ovary. The edible part of the fruit is generally known as pericarp. It is divided into epicarp, mesocarp, and endocarp. True fruits include cherries, plums, peaches, etc. At the time of fruit formation, the other whorls of the flower such as petals, sepals, and stamens degenerate in true fruits but if they persist they lead to the formation of false fruits.
So, the correct answer is ‘Apple’.

Note: Some example of false fruits along with the plant organ from which the accessory tissue is derived are-
-Fruits derived from the hypanthium- They include pomes, for example, apple and pear.
-Fruits derived from the perianth- They include fruits of the Nyctaginaceae family.
-Fruits derived from the receptacle- They include fig, mulberry, pineapple, and strawberry.
-Fruits derived from calyx- They include Gaultheria procumbens and Syzygium jambos.
