Question

The fruit of rice and wheat is called:
A. Achene
B. Siliqua
C. Follicle
D. Caryopsis

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definition of indehiscent fruit. This is a fruit in which the seed coat has merged with the ovary wall. Wheat or rice is a straightforward sort of fruit produced by a single ovary of a single flower. This is an Indehiscent fruit, which does not split along clear lines when mature to release seeds.

Complete step by step solution:
Indehiscent fruit is a type of botanical that does not contain seeds. This includes bananas, papayas, pineapple, oranges, and some types of grapefruit.
Indehiscent fruit is a fruit that does not enter into and release the seed within the fruit itself. This means that they will not mature or ripen, and instead will be eaten fresh as it is.
Rice or wheat is an indehiscent fruit, which is a dry fruit that does not open to shed its seeds when mature and is created from a single carpel. Grain, also known as a caryopsis, is a form of fruit in which one seed is bonded to the pericarp. Caryopsis can be found in the fruit of the Poaceae or Graminaece family.
Therefore, the fruit of rice and wheat is called Caryopsis.
