Question

Why are Apples and Cashews not called true fruits?

Answer 1

Hint: Fruits are the means through which angiosperms (flowering plants) disseminate their seeds. Edible fruits, in particular, have long been propagated by humans and animals in a symbiotic relationship that serves as a means of seed dispersal for one group and nutrition for the other; in fact, humans and many animals have become reliant on fruits as a food source.

Complete answer:
Fruits are only produced by flowering plants or angiosperms, as we all know.
A series of processes, including pollination, fertilization, the formation of the zygote, and the ovary's development into a fruit, is used to produce fruits from a flower. Fruits are divided into two categories.
True fruits: The true fruit is defined as the fruit that develops from the flower's fertilized ovary.
Examples: True fruits include watermelon, lemon, cherry, and blueberries.
False fruits: False fruits are fruits that are formed from the ripened ovary and other parts of the flower, such as the base or receptacle, the perianth, and so on.
False fruits include apples, bananas, cashews, and strawberries, to name a few.
This is why apples and cashews are referred to as false fruits rather than true fruits. Because of the way these fictitious fruits are created, ovary along with other accessory floral parts

Note:
Parthenocarpy is a condition in which fruits develop without seeds forming. In the year 1902, this method of fruit production was introduced. This is primarily due to the lack of fertilization, pollination, and embryo development in plants. Parthenocarpic fruit is a botanical term that means "virgin fruit". The majority of these fruits are seedless.
